Integrated Library Systems (ILS)

Brief description: Integrated library systems usually consist of a database, software to act on the database, and two graphical user interfaces (one for librarians and one for patrons). An ILS controls what the public sees in the OPAC and provides many functions for librarians both to add information to the OPAC and controls for handling library materials and functions.

How is it used in a library? An ILS includes the capability to checkout and discharge materials while simultaneously updating the public OPAC. An ILS also allows librarians to track materials from the time they are ordered to their eventual withdrawal. Cost information can be stored along with circulation statistics. An ILS also enables librarians to keep patrons on record, which is necessary for assessing fines and notifying patrons of holds or overdue material. An ILS also enables patrons to conduct web-based activities related to their library account, such as renewing materials and placing holds.

Expected Social Impact: An Integrated Library System allows for the shortest delay between the transfer of knowledge between library staff and library users. An ILS allows materials to be added to the OPAC as soon as they are catalogued. Items which are checked out or returned are updated in the OPAC as soon as the transaction is processed. Integrated Library Systems become part of the disintermediation of the library because the ILS acts in place of the librarian. Instead of talking to a librarian, a patron is able to find the information they need at a computer terminal. They usually do not realize that the information is there because the librarian put it there in the first place.
