Information will be selected from the source by following the principles and guidelines specified in AACR2. 2. Information will be entered into the computer system following the principles and guidelines of MARC21 with an eye toward future manipulation of the data Slide4: 3. Information must be entered accurately with regard to punctuation, spelling, and form with principles of authority control applied. 4. Information should be selected and entered so that it can be easily retrieved by the user for whom the item is targeted to and is able to grow and adapt to the changing needs of the user. 5. The process must be economically viable. ACCESS POINTS: ACCESS POINTS Access points are the places where a user can look for an item in a system. The traditional access points are: à Author à Title à Series à Subject à Added entriesIt is important to remember that these were designed for access in a paper, or card catalog. Computer-based systems give us the opportunity to access information in different ways, most notably with Boolean operators and via keywords. : It is important to remember that these were designed for access in a paper, or card catalog. Computer-based systems give us the opportunity to access information in different ways, most notably with Boolean operators and via keywords. RECORD CONSTRUCTION : RECORD CONSTRUCTION The method we use to store information in a computer is the MARC format, also known as MARC21. It is a method of organizing and storing information in a computer so that library automation system can retrieve it. The component parts of a MARC record are Fields, Tags, Subfields, and Indicators Fields: Fields A field is the part of the MARC record that contains broad quantities of information. For example, there is a field for the title, a field for publication information, fields for subjects, and so on. Tags: Tags A tag is a three-digit number that indicates what type of information is recorded in a specific area. It is important to note that tags must be three digits long, must be numerical, but do not have to be in numerical order in a MARC record, although they may be. Examples: 020 245 650 : Examples: 020 245 650 Subfields: Subfields Subfields are used to break down information in a tag into smaller units. When it contains large quantities of information, a tag becomes cumbersome to use and access. A subfield let’s us break down the information into small component units. Examples:245 $aHow green was my valley :$ba study in valley topography /$cRay Garden. Subfields are usually denoted by a lower case letter, although sometimes numbers are used. The subfields are different for each tag. : Examples: 245 $aHow green was my valley :$ba study in valley topography /$cRay Garden. Subfields are usually denoted by a lower case letter, although sometimes numbers are used. The subfields are different for each tag. Indicators: Indicators Indicators are used in conjunction with tags to instruct the computer how to file and organize the data. Each tag can have two indicators. Some tags will use the first indicator only, some the second only, some both, and some none at all. Which indicators are used, and what they mean is different from position to position and from tag to tag. It is critical that you understand what each position means and how your system uses it. If you discover that records are not accessible in your system, particularly subjects and titles, check the indicator values. Examples: 245 10 505 0 650 0: Examples: 245 10 505 0 650 0PUNCTUATION: PUNCTUATION Punctuation is perhaps the most overlooked part of the MARC record. Marks of punctuation serve as “signposts” for the system, telling it where specific pieces of information end, as well as telling it what to expect next. Example: $aThe pit and the pendulum / Edgar Allen Poe – The open boat / Stephen Crane – The bride comes to Yellow Sky / Bret Harte. : Example: $aThe pit and the pendulum / Edgar Allen Poe – The open boat / Stephen Crane – The bride comes to Yellow Sky / Bret Harte. In the above example, the system could, in the future, be programmed to look for specific titles in the above Contents string. The importance of correct punctuation cannot be over-emphasized. ORDER OF INFORMATION: ORDER OF INFORMATION The idea of the order of information goes back to those days in school when they told you that “spelling counted.” While you should always endeavor to spell information correctly, it is even more important to do so for those items at the beginning of a tag. Transposing a letter at the beginning of an indexed phrase can render that piece of information irretrievable. Examples:: Examples: 245 Zoos of North America 245 Zoos of North Ameriac 245 Ozos of North America It is obvious from the above examples that, while the last two each have a typo in them, the middle title would be retrievable if a user entered the search term Zoos of North America while the third title would be completely lost to anyone doing a title search. TAG MNEMONICS: TAG MNEMONICS 0XX Used for information that is particularly relevant to the computer’s use. Patrons will not use this information, librarians only rarely. 1XX Main entries, or author information 2XX Title and publication information (including variant forms of the title) 3XX Physical description and collation 4XX Series informationTAG MNEMONICS cont.: TAG MNEMONICS cont. 5XX Notes and miscellaneous information 6XX Subjects 7XX Added entries, like joint authors, editors, and analytical title information (e.g. episodes from a videorecording or individual parts of an anthology.) 8XX Series added information 9XX Locally defined (system) informationPARALLEL CONSTRUCTION: PARALLEL CONSTRUCTION There are some areas of the MARC record that are under authority control. These tags follow a consistent structure from one to another. These tags are the 1XX, 4XX, 6XX, and 7XX. They are constructed in the same manner, based on the values entered in the last two numeric positions. Slide22: X00 Personal names X10 Corporate names X11 Conference or meeting names X30 Uniform title X40 Title proper information (not in all areas) X50 Topical information X51 Geographic information Slide23: Note that sometimes the information in two different numerical tags can be identical, even though each is being used differently. For example: 100 Rand, Ayn This would be the entry for a book by Ayn Rand. 600 Rand, Ayn This would be the entry for a book about Ayn Rand. COMMON CATALOGING ERRORS: COMMON CATALOGING ERRORS 1. Incorrect indicator values Use of the wrong indicator value can cause a system to mis-index a term. Particularly prevalent in title and subject areas. 2. Failure to accurately code the fixed field (008) area Not coding information properly here results in failed detailed searches, particularly when searching by year of publication, genre, or target audience. 3. Typographical errorsMisspelling a word, especially if at the beginning of an indexed tag, results in failed searches. Misspelled words also result in failed keyword searches. 4. “Fixing” title entries in the 245 tagThere is a strong tendency to “fix” entries in searched tags so that the “right” results are achieved. This can actually result in failed searches by users who use the “correct” terms.: 3.

This can actually result in failed searches by users who use the “correct” terms. 5. Use of non-standard subject headingsResist the urge to create local subject headings, particularly if they deviate from the controlled vocabulary you use (Sears, LCSH, etc.) This causes problems with records imported from vendors, from users who access your catalog via the Internet, or from patrons confused by local use that deviates from what they encounter at other libraries. It’s also more work for you. : 5.

Adjusting cataloging so that it “works” in your automation systemThe temptation to modify cataloging information so that it is accessed “logically” by the system is a dangerous path. While it may “work” today, if the software is modified or if you migrate to another system, your records may not work properly or may be inaccessible, forcing you to redo the records. : 7.

Its also confusing to patrons looking for a particular item. : 8. Not practicing good authority control More on this later.

AUTHORITY CONTROL : AUTHORITY CONTROL Authority control is the process that makes certain that the same information is entered the same way each time it is used. EXAMPLE Clemens, Samuel becomes Twain, Mark : EXAMPLE Clemens, Samuel becomes Twain, Mark Authority records can also be used to generate cross-references in the author and subject databases. The importance of authority control cannot be stressed enough. Databases are not immune to the same laws of entropy that afflict all things on the face of the earth. Authority control helps us to lessen the impact of entropy and to reverse its effects. Librarians should never, ever compromise authority control, no matter how trivial it seems. What is a “minor” change today can have far-reaching consequences. : Authority records can also be used to generate cross-references in the author and subject databases.

First: It is used to define terms that are acceptable for use in a controlled vocabulary. These can be names, phrases, titles, or topics. Second: It is used to define the process of applying those terms to specific area(s) of the MARC record. : AUTHORITY CONTROL DEFINITION Authority control is a term used to define two separate but related operations. First: It is used to define terms that are acceptable for use in a controlled vocabulary. These can be names, phrases, titles, or topics. Second: It is used to define the process of applying those terms to specific area(s) of the MARC record. The result of this is that we create a system which defines which terms are acceptable in a controlled environment, then applies those terms to the appropriate area, referencing incorrect terms to those acceptable terms or headings. Authority control is a pre-coordinate system. It creates acceptable search and indexing terms before a bibliographic record is entered into an online catalog. : The result of this is that we create a system which defines which terms are acceptable in a controlled environment, then applies those terms to the appropriate area, referencing incorrect terms to those acceptable terms or headings. Authority control is a pre-coordinate system. It creates acceptable search and indexing terms before a bibliographic record is entered into an online catalog. Authority control is related to, but not equivalent to bibliographic records. Bibliographic records depend on authority records to validate the information in them, but authority records do not have to have a complimentary bibliographic record (although this situation is not normally considered desirable.) Authority records can be used to generate cross-references, but is not primarily a cross-reference system. : Authority control is related to, but not equivalent to bibliographic records.

PRE-COORDIANTE vs. POST-COORDINATE : PRE-COORDIANTE vs. POST-COORDINATE PRE-COORDINATEIn a pre-coordinate system, the cataloger determines which names, words, or phrases the patron will use to find the item, and then verify if those terms are valid according to the controlled vocabulary. Generally, these terms are defined in some type of thesaurus or list which is accepted for use by the users of the system. Using these terms users will recover fewer items during a search, but most of those items will be relevant to their needs. This type of search is said to have low recall but high precision. : PRE-COORDINATE In a pre-coordinate system, the cataloger determines which names, words, or phrases the patron will use to find the item, and then verify if those terms are valid according to the controlled vocabulary.

Using these terms users will recover fewer items during a search, but most of those items will be relevant to their needs. This type of search is said to have low recall but high precision. POST-COORDINATEIn a post-coordinate system, index and search terms are constructed without regard to the validity of those terms in the larger context.

While some Internet browsers have “subject” areas, they utilize uncontrolled terms. This means that search interfaces, such as Yahoo and Alta Vista would be considered post-coordinate indexes. In fact, many web designers choose the words used in the meta-tags carefully so that a given search will “hit” their particular web page. The use of XML is a step in the direction of bringing more control to the Internet. : While some Internet browsers have “subject” areas, they utilize uncontrolled terms.

Rather, they are searching indexes based on the specific tags in those records. For example, the Author index may contain information from the 100, 110, 111, 700, 710, 711 tags of the bibliographic record. When the user “selects” a particular entry, index pointers then “collect” the rest of the record for screen display. These indexes are not limited to information from our bibliographic records. They can also contain information from our authority records as well. This means that the Author index in a system may contain the following: : INDEXES When users search a library’s collection, they are not actually searching the bibliographic records.

When considering records from outside sources, remember the following axioms: 1. No matter the source, records will usually require some type of editing.2. You get what you pay for.3. Time searching can often exceed time cataloging.4. Make certain the record matches the item in hand.5. Don’t forget to download matching authority records.

Information will be selected from the source by following the principles and guidelines specified in AACR2. 2. Information will be entered into the computer system following the principles and guidelines of MARC21 with an eye toward future manipulation of the data Slide4: 3. Information must be entered accurately with regard to punctuation, spelling, and form with principles of authority control applied. 4. Information should be selected and entered so that it can be easily retrieved by the user for whom the item is targeted to and is able to grow and adapt to the changing needs of the user. 5. The process must be economically viable. ACCESS POINTS: ACCESS POINTS Access points are the places where a user can look for an item in a system. The traditional access points are: à Author à Title à Series à Subject à Added entriesIt is important to remember that these were designed for access in a paper, or card catalog. Computer-based systems give us the opportunity to access information in different ways, most notably with Boolean operators and via keywords. : It is important to remember that these were designed for access in a paper, or card catalog. Computer-based systems give us the opportunity to access information in different ways, most notably with Boolean operators and via keywords. RECORD CONSTRUCTION : RECORD CONSTRUCTION The method we use to store information in a computer is the MARC format, also known as MARC21. It is a method of organizing and storing information in a computer so that library automation system can retrieve it. The component parts of a MARC record are Fields, Tags, Subfields, and Indicators Fields: Fields A field is the part of the MARC record that contains broad quantities of information. For example, there is a field for the title, a field for publication information, fields for subjects, and so on. Tags: Tags A tag is a three-digit number that indicates what type of information is recorded in a specific area. It is important to note that tags must be three digits long, must be numerical, but do not have to be in numerical order in a MARC record, although they may be. Examples: 020 245 650 : Examples: 020 245 650 Subfields: Subfields Subfields are used to break down information in a tag into smaller units. When it contains large quantities of information, a tag becomes cumbersome to use and access. A subfield let’s us break down the information into small component units. Examples:245 $aHow green was my valley :$ba study in valley topography /$cRay Garden. Subfields are usually denoted by a lower case letter, although sometimes numbers are used. The subfields are different for each tag. : Examples: 245 $aHow green was my valley :$ba study in valley topography /$cRay Garden. Subfields are usually denoted by a lower case letter, although sometimes numbers are used. The subfields are different for each tag. Indicators: Indicators Indicators are used in conjunction with tags to instruct the computer how to file and organize the data. Each tag can have two indicators. Some tags will use the first indicator only, some the second only, some both, and some none at all. Which indicators are used, and what they mean is different from position to position and from tag to tag. It is critical that you understand what each position means and how your system uses it. If you discover that records are not accessible in your system, particularly subjects and titles, check the indicator values. Examples: 245 10 505 0 650 0: Examples: 245 10 505 0 650 0PUNCTUATION: PUNCTUATION Punctuation is perhaps the most overlooked part of the MARC record. Marks of punctuation serve as “signposts” for the system, telling it where specific pieces of information end, as well as telling it what to expect next. Example: $aThe pit and the pendulum / Edgar Allen Poe – The open boat / Stephen Crane – The bride comes to Yellow Sky / Bret Harte. : Example: $aThe pit and the pendulum / Edgar Allen Poe – The open boat / Stephen Crane – The bride comes to Yellow Sky / Bret Harte. In the above example, the system could, in the future, be programmed to look for specific titles in the above Contents string. The importance of correct punctuation cannot be over-emphasized. ORDER OF INFORMATION: ORDER OF INFORMATION The idea of the order of information goes back to those days in school when they told you that “spelling counted.” While you should always endeavor to spell information correctly, it is even more important to do so for those items at the beginning of a tag. Transposing a letter at the beginning of an indexed phrase can render that piece of information irretrievable. Examples:: Examples: 245 Zoos of North America 245 Zoos of North Ameriac 245 Ozos of North America It is obvious from the above examples that, while the last two each have a typo in them, the middle title would be retrievable if a user entered the search term Zoos of North America while the third title would be completely lost to anyone doing a title search. TAG MNEMONICS: TAG MNEMONICS 0XX Used for information that is particularly relevant to the computer’s use. Patrons will not use this information, librarians only rarely. 1XX Main entries, or author information 2XX Title and publication information (including variant forms of the title) 3XX Physical description and collation 4XX Series informationTAG MNEMONICS cont.: TAG MNEMONICS cont. 5XX Notes and miscellaneous information 6XX Subjects 7XX Added entries, like joint authors, editors, and analytical title information (e.g. episodes from a videorecording or individual parts of an anthology.) 8XX Series added information 9XX Locally defined (system) informationPARALLEL CONSTRUCTION: PARALLEL CONSTRUCTION There are some areas of the MARC record that are under authority control. These tags follow a consistent structure from one to another. These tags are the 1XX, 4XX, 6XX, and 7XX. They are constructed in the same manner, based on the values entered in the last two numeric positions. Slide22: X00 Personal names X10 Corporate names X11 Conference or meeting names X30 Uniform title X40 Title proper information (not in all areas) X50 Topical information X51 Geographic information Slide23: Note that sometimes the information in two different numerical tags can be identical, even though each is being used differently. For example: 100 Rand, Ayn This would be the entry for a book by Ayn Rand. 600 Rand, Ayn This would be the entry for a book about Ayn Rand. COMMON CATALOGING ERRORS: COMMON CATALOGING ERRORS 1. Incorrect indicator values Use of the wrong indicator value can cause a system to mis-index a term. Particularly prevalent in title and subject areas. 2. Failure to accurately code the fixed field (008) area Not coding information properly here results in failed detailed searches, particularly when searching by year of publication, genre, or target audience. 3. Typographical errorsMisspelling a word, especially if at the beginning of an indexed tag, results in failed searches. Misspelled words also result in failed keyword searches. 4. “Fixing” title entries in the 245 tagThere is a strong tendency to “fix” entries in searched tags so that the “right” results are achieved. This can actually result in failed searches by users who use the “correct” terms.: 3.

This can actually result in failed searches by users who use the “correct” terms. 5. Use of non-standard subject headingsResist the urge to create local subject headings, particularly if they deviate from the controlled vocabulary you use (Sears, LCSH, etc.) This causes problems with records imported from vendors, from users who access your catalog via the Internet, or from patrons confused by local use that deviates from what they encounter at other libraries. It’s also more work for you. : 5.

You need to know what tags are indexed and what searches retrieve that information. This leads us to our next common error: : 6.

Adjusting cataloging so that it “works” in your automation systemThe temptation to modify cataloging information so that it is accessed “logically” by the system is a dangerous path. While it may “work” today, if the software is modified or if you migrate to another system, your records may not work properly or may be inaccessible, forcing you to redo the records. : 7.

AUTHORITY CONTROL : AUTHORITY CONTROL Authority control is the process that makes certain that the same information is entered the same way each time it is used. EXAMPLE Clemens, Samuel becomes Twain, Mark : EXAMPLE Clemens, Samuel becomes Twain, Mark Authority records can also be used to generate cross-references in the author and subject databases. The importance of authority control cannot be stressed enough. Databases are not immune to the same laws of entropy that afflict all things on the face of the earth. Authority control helps us to lessen the impact of entropy and to reverse its effects. Librarians should never, ever compromise authority control, no matter how trivial it seems. What is a “minor” change today can have far-reaching consequences. : Authority records can also be used to generate cross-references in the author and subject databases.

First: It is used to define terms that are acceptable for use in a controlled vocabulary. These can be names, phrases, titles, or topics. Second: It is used to define the process of applying those terms to specific area(s) of the MARC record. : AUTHORITY CONTROL DEFINITION Authority control is a term used to define two separate but related operations. First: It is used to define terms that are acceptable for use in a controlled vocabulary. These can be names, phrases, titles, or topics. Second: It is used to define the process of applying those terms to specific area(s) of the MARC record. The result of this is that we create a system which defines which terms are acceptable in a controlled environment, then applies those terms to the appropriate area, referencing incorrect terms to those acceptable terms or headings. Authority control is a pre-coordinate system. It creates acceptable search and indexing terms before a bibliographic record is entered into an online catalog. : The result of this is that we create a system which defines which terms are acceptable in a controlled environment, then applies those terms to the appropriate area, referencing incorrect terms to those acceptable terms or headings.

Authority control is related to, but not equivalent to bibliographic records. Bibliographic records depend on authority records to validate the information in them, but authority records do not have to have a complimentary bibliographic record (although this situation is not normally considered desirable.) Authority records can be used to generate cross-references, but is not primarily a cross-reference system. : Authority control is related to, but not equivalent to bibliographic records.

PRE-COORDIANTE vs. POST-COORDINATE : PRE-COORDIANTE vs. POST-COORDINATE PRE-COORDINATEIn a pre-coordinate system, the cataloger determines which names, words, or phrases the patron will use to find the item, and then verify if those terms are valid according to the controlled vocabulary. Generally, these terms are defined in some type of thesaurus or list which is accepted for use by the users of the system. Using these terms users will recover fewer items during a search, but most of those items will be relevant to their needs. This type of search is said to have low recall but high precision. : PRE-COORDINATE In a pre-coordinate system, the cataloger determines which names, words, or phrases the patron will use to find the item, and then verify if those terms are valid according to the controlled vocabulary.

Using these terms users will recover fewer items during a search, but most of those items will be relevant to their needs. This type of search is said to have low recall but high precision. POST-COORDINATEIn a post-coordinate system, index and search terms are constructed without regard to the validity of those terms in the larger context. As a general rule, the use of these terms by a patron recovers more items, but fewer items which are relevant. This is said to have high recall but low precision. : POST-COORDINATE In a post-coordinate system, index and search terms are constructed without regard to the validity of those terms in the larger context. As a general rule, the use of these terms by a patron recovers more items, but fewer items which are relevant. This is said to have high recall but low precision. While some Internet browsers have “subject” areas, they utilize uncontrolled terms. This means that search interfaces, such as Yahoo and Alta Vista would be considered post-coordinate indexes. In fact, many web designers choose the words used in the meta-tags carefully so that a given search will “hit” their particular web page. The use of XML is a step in the direction of bringing more control to the Internet. : While some Internet browsers have “subject” areas, they utilize uncontrolled terms.

Again, this aids in the computerized matching of them. : TAG CONSTRUCTION Tags in authority records are constructed exactly like their counterparts in bibliographic records.

If anything, their structure is much more logical. Each authority record must have a 1XX tag, and only a single 1XX tag. This is the valid heading that can be used in the system. The most commonly used 1XX tags are: 100 Heading – Personal Name110 Heading - Corporate Name111 Heading - Meeting Name130 Heading - Uniform Title150 Heading - Topical Term151 Heading - Geographic Name : AUTHORITY RECORD CONSTRUCTION Authority record construction is similar but not identical to bibliographic records.

Somehow, they must point to the cataloger, and possibly the library patron, to the correct term. These tags in the authority records are called the See tags. If a user of the system enters a search term that “hits” one of these, they should be directed to the correct term. These terms in the authority record are in the 4XX tags: 400 See From Tracing - Personal Name410 See From Tracing - Corporate Name411 See From Tracing - Meeting Name430 See From Tracing - Uniform Title450 See From Tracing - Topical Term451 See From Tracing - Geographic Name : Having these terms alone is not enough, and they cannot stand alone in the authority record.

Rather, they are searching indexes based on the specific tags in those records. For example, the Author index may contain information from the 100, 110, 111, 700, 710, 711 tags of the bibliographic record. When the user “selects” a particular entry, index pointers then “collect” the rest of the record for screen display. These indexes are not limited to information from our bibliographic records. They can also contain information from our authority records as well. This means that the Author index in a system may contain the following: : INDEXES When users search a library’s collection, they are not actually searching the bibliographic records.

First of all, export all the records and send them to a reputable vendor for authority checking and validation.Second, load the corrected bibliographic records into the database, overlaying the old records.Third, validate the appropriate tags in new bibliographic records added to the system. This can either be done on a record-by-record basis, or it can be accomplished by exporting the records on a regular basis and having them checked by an authority vendor.Finally, add/update headings as necessary for your specific library. : WHERE TO GO FROM HERE If a library never has had any authority control work performed on its database, it should do so before progressing any further down the authority control path.

When considering records from outside sources, remember the following axioms: 1. No matter the source, records will usually require some type of editing.2. You get what you pay for.3. Time searching can often exceed time cataloging.4. Make certain the record matches the item in hand.5. Don’t forget to download matching authority records.
