An integrated library system (ILS) is a suite of software modules that help automate core library functions like circulation, acquisitions, cataloging, and serials control. The key elements of an ILS include a central processing unit, barcode wand, keyboard, printer, and storage device for circulation functions. Acquisitions modules maintain item records, vendor information, and accounting data. Cataloging modules handle MARC and authority records and link to bibliographic utilities. Serial control is complex due to the periodic nature of serials. OPAC interfaces have evolved from character-based to web-based. Integration with other resources is important. Selection of an ILS requires consideration of rapid vendor changes and their impact on staff and patrons.
26. Acquisitions Transmit data to vendors (via printed forms or, increasingly, electronically) Integrate into the OPAC (e.g. display "on order" records to the public) Must:
28. Cataloging Must be able to handle standard formats such as MARC and MARC Holdings as well as integrate non-MARC formats in certain situations (e.g. archival records)...
38. Serials Often the most complex automation task due to the periodic nature of serials and the labor intensive efforts for retrospective conversion of manual serial files.
61. Selection Rapid Change - the average lifespan of an ILS is 3-5 years; vendors are consolidating and merging ...
62. Selection This rapid rate of change will have an impact on staff training, patron training, budgets, workflow -- in essence, all elements of your library work.
63. Selection With proper planning, the disruptions of incurred with implementing a new system can be minimized (but never eliminated!).
