Collection Analysis CD.

CD-ROM Review

Collection Analysis CD

The OCLC/Amigos package Collection Analysis CD provides an easy-to-use method of performing indepth analysis of an academic library's collection, using similar collections as a basis of comparison. Results of the analysis can be used to identify strengths and weaknesses of the collection, to formulate a collection development policy, and to track the effect of that policy on the collection.

The standard Collection Analysis CD package comes with 1.6 million OCLC records on a CD-ROM disc. These records consist of non-serial printed materials that were published within a recent 10-year period.

Collection Comparison

The collection analysis offered by the package is based on selection of comparison collection(s), called a peer group, against which the collection at the user's library is to be compared.

The Collection Analysis CD comes with the citations for the user's collection on floppy disks. These disks are copied from OCLC records, so the user's library must be a member of OCLC.

The package also comes with 14 peer groups to choose from. Each peer group includes libraries (Association of Research Libraries and academic libraries) with certain common characteristics, such as collection size or degree program. As an added cost option, any of 99 individual OCLC academic libraries can be used as a peer group.

Peer groups, and discs containing the user's current collection, can be updated annually at a cost of $1,000 for each update.

Subject Categories

Collection analysis comparisons are made on subject categories. Available categories include 32 Library of Congress (LC) and the National Shelf List 500 (NSL) categories.

Once the peer group is selected, the package can produce a Collection Counts report. This report displays the number of titles, in each LC classification division, held by one or more of the peer group libraries, alongside the number of titles held by the user's collection. Comparative holdings numbers are displayed, and the number of unique titles (held by only one member of the peer group) are also shown.

A Collection Overlap report displays the percent of peer group titles and holdings which appear in the user's collection for each LC subject division.

National Shelf List 500 for Finer Analysis

For a more detailed subject analysis, a SubCollection Counts report displays titles and holdings broken down into National Shelf List 500 (NSL) subject divisions. Again, the number of titles in each division held by one or more of the peer group libraries is listed alongside the number of titles held by the user's collection. Comparative holdings numbers are displayed, and the number of unique titles is also shown.

A SubCollection Proportions report compares the number of titles held by the user's library, in each NSL division, to the holdings of an average library in the peer group. This report also displays the percent of the peer and user's collections taken up by titles in each NSL category.

Gap titles (those held by one or more peer group libraries, but missing from the user's collection) are analyzed in separate reports, for each LC and NSL division.

The statistical reports can help to identify gaps in the holdings at the user's library. The analysis can also be used to analyze the extent of overlap and uniqueness of one collection compared to another.

Individual Titles Display

For further analysis and action, lists of author names with short titles and publication year can be displayed for each LC division. Complete lists of the user's collection, and of the peer group collections can be displayed. Lists of titles in the user's collection which are the same as those in the peer group, and gap titles (not in the user's collection) can also be displayed. Finally, titles unique to the user's collection, and titles held by only one peer group library, can be displayed.

When one of these titles lists is on the screen, the user can highlight any title and get a display that includes the OCLC and ISBN numbers for that title.

To aid in subsequent collection development activities, titles on the CD-ROM disc can be exported to an ASCII file, which can then be manipulated with a word processor, or exported to another computer system.
