6. Custom Holdings

The “custom holdings” feature on OCLC allows libraries to program the computer to randomly select their lender string from pre-determined libraries. Library symbols are arranged in “custom holdings groups” and the groups are arranged in “paths”. The paths tell the computer to select from the first group in the path, and if necessary to go to the second group, then the third group and so on. This saves time by greatly reducing the need to check lending policies. If set up carefully, it can also facilitate a more even distribution of lending among libraries.

Custom Holdings
Groups

A custom holdings group can contain an infinite number of libraries. The libraries in any given group should have the same geographic relationship to the borrowing library. For example, one group may contain the symbols of the libraries lying within the same metropolitan area. Another group might consist of libraries within a 200-mile radius. Libraries that loan genealogy materials at no charge, or libraries that charge for genealogy loans may another type of group to create.

Custom Holdings
Paths

A different holdings path can be set up for each type of request. For
Paths example, a path can be created for loans patrons are not willing to pay for. Another one for patrons willing to pay for loans would include the free loan groups followed by groups of libraries that charge for loans. Paths can also be created for free copies, charged copies, genealogy loans, genealogy copies, and audio-visual loans.
Any number of custom holdings groups can be placed in a custom holdings path.
