Pragmatics of Library Software Modules : Cataloguing Maintenance Titles-in-Process, Update Holdings, Call Nos., Subject Updates, Keywords, etc.. Transfer of Data to OPAC & Circulation Classification Codes UDC, DDC, CC etc.. User Services & Products CAS SDI Bibliographies Printing Catalog cards etc..

Cataloguing Standards: 

Cataloguing Standards ISBD MARC Common Communication Format ISO 9702 Z39.50

CCF: 

CCF Conform to ISO 2709 Core record consists of Mandatory Data essential to bibliographic description Core Record augmented with optional data elements Techniques would be devised for accommodating levels, relationships and links between bibliographic entities

CCF: 

CCF INFORMATION SYSTEM DATA BASE INPUT FORMAT STORAGE FORMAT RETRIEVAL FORMAT DISPLAY FORMAT RECORDS

Z.3950: 

Z.3950 OSI Model Database source systems Client-server communication state-of-art microcomputer workstations Linked System Protocol (OSI) Lower Level Interaction physical, Data, Network &Transport Upper Level Layers Session, Presentation &Application

Z.3950: 

Z.3950 Integrate Text & Graphics Support Multimedia Support complex documents Multitasking operations Large, fast Mass Storage devices Electronic mail Support Data Acquisition Address Substantial amount of Memory User Customize permission Enough speed to permit intensive processing

Z.3950: 

Z.3950 Functions Initialization Security Validation Searching Present Record Accounting Facility Delete Facility Termination Facility

Pragmatics of Library Software Modules : Information Storage & Retrieval: 

Pragmatics of Library Software Modules : Information Storage & Retrieval Searching Sequentially Slow Index Computer-generated Index Single word, Compound terms & whole (sub) fields Indexing of Stored Information Max. No. of Characters indexed per term Max. no. of different indexes per file Different Ways of Indexing single, compound and Whole Fields

Pragmatics of Library Software Modules: 

Pragmatics of Library Software Modules Choice of each file to be indexed Indexing of tagged words only Availability of Stopword list user defined & maximum no stopwrods Indexing of New Records/batch indexing speed of indexing Size of indexed data Building / Removing of Indexes or Changing the type of Index Use of controlled index terms Thesaurus

Pragmatics of Library Software Modules: 

Pragmatics of Library Software Modules Retrieval of Stored Information Searching through an Index or Sequential Non-indexed through Sequential search Indexes can displayed/printed; relations through Thesaurus Availability of Index list on the screen as search terms Default search fields Indication of a field or tag is required Boolean searching with AND, OR and NOT operators More operators with parenthesis Search terms and/or previous search terms can be combined directly in Boolean searches

Pragmatics of Library Software Modules: 

Pragmatics of Library Software Modules Presence of KEEP command offers full boolean possibilities Proximity searching Searching on Truncated terms left, right and internal masking Range searching From, to, greater than, lessthan Saving the search strategy Output of Data Standard formats Display, Printing &Writing of data

Pragmatics of Library Software Modules: 

Pragmatics of Library Software Modules User defined output formats Sorting of data in varies fields (multiple) Including field tags or names Search terms can be highlighted Formats for direct data exchange Reference lists according to Journal styles

Pragmatics of Library Software Modules : Circulation: 

Pragmatics of Library Software Modules : Circulation Issues Returns Reserves Membership Records Registration, Category, Institute member, Define subjects for SDI Collection Updates Display Titles, Copy missing, Damaged, Withdrawn, Binding etc.. Inter Library Loan

Pragmatics of Library Software Modules : Circulation: 

Pragmatics of Library Software Modules : Circulation Enquiries Status, Transactions Log, Charges, Missing, Withdrawn etc.. User Communication Reserves, Overdues, etc.. Reports \ Printing System Setup No. of Days issues, Category wise issues, Reference,Serials issue etc..

Pragmatics of Library Software Modules : Serials Control: 

Pragmatics of Library Software Modules : Serials Control New Subscription New Titles, Approval procedures, Order, Subscription Details, Invoicing, Payment, Correspondence, etc.. Renewals Issues Received (Kardex) Claims Monitoring Periodical Reminders, Binding Enquiries Circulation of Back issues

Classical Retrieval systems : CDS/ISIS: 

Classical Retrieval systems : CDS/ISIS UNESCO Information Storage & Retrieval Menu Driven Choosing the Existing Database Changing language Changing or Adding Data Searching the Database Sorting & Printing; writing on file Creating or Updating the indexes Creating or changing database definition

Classical Retrieval systems : CDS/ISIS: 

Classical Retrieval systems : CDS/ISIS reorganizing, exporting in ISO-format creating a back-up of a database Utility programs Programming additional modules in Pascal according to ISO-format Very Comprehensive & well-organized manual Field Definition Table Simple Field Structure Subfield within field Comprehensive Search Facility a.ANY file for synonyms and narrower terms

Classical Retrieval systems : CDS/ISIS: 

Classical Retrieval systems : CDS/ISIS Format Tables for output data Retrieved data can be exported ISO format Very powerful & Versatile program It is fast on relatively old & slow PC’s CDS/ISIS Ver 3.0 Network use & Unix Version

Classical Retrieval systems : CDS/ISIS: 

Classical Retrieval systems : CDS/ISIS Limitations User Manual is essential very Comprehensive Extensive menu driven, confusing No integration FDT cannot be created automatically FDT cannot be duplicated (only through MS-DOS) Not easy to change existing data entry sheet Worksheet composed of several pages (screens) Quantity of information on content is more Indexing process long time, lengthy process, lot of space etc..

Classical Retrieval systems : CDS/ISIS: 

Classical Retrieval systems : CDS/ISIS Format Tables are complicated to create No high lighting or special colors for retrieved data Restrictions on Display of databases, Six Characters of Database name, user print formats Screen presentations are character oriented

Integrated Library Software : Libsys: 

Integrated Library Software : Libsys Generalized & Comprehensive Library Software Package Integrated with Multi-user Capability Menu Driven Modularized Approach Supporting Utilities Security through Modules and Operations Parametrically Defined

Integrated Library Software : Libsys: 

Integrated Library Software : Libsys LibSys Acquisition Cataloguing Circulation Serials Control OPAC

Integrated Library Software : Libsys: 

Integrated Library Software : Libsys Limitations Cost Documentation Manuals On-line Help Serials Control Backup Not incremental Customization Slow Customer Support

Conclusion: 

Conclusion No software package can meet all the requirements of a given library system. Inevitably, some compromises will be needed in work flows, input, output and report formats. Customization takes lot of time, by doing that other problems could arise. Therefore while evaluating the Library Software it is important to prioritize the requirements and make sure that the chosen software meets most, if not all the high priority requirements
