For selected analyses, results may be displayed according to the number of libraries that hold a given title.
For WorldCat Comparisons, this dimension shows how widely your library's items are held within WorldCat, that is, whether an item is held uniquely by your library or held by you and one, two, three (and so on) other libraries.
For ILL Analyses, this dimension shows the total number of items requested (Borrower) or shipped (Lender). You can view data by annual or quarterly totals.

The Data to Analyze screen lists all of the analyses available to your library.
The Analysis Results screen presents the results of an analysis in a spreadsheet-style table. Information viewed on this screen includes:
My Library. This analysis presents your library’s holdings – and only your library’s holdings – according to your selected analysis dimensions..
WorldCat Comparison. This analysis compares your library’s holdings to all of WorldCat, according to your selected analysis dimensions. It shows how many of your holdings are unique to your collection and how many are held by other libraries as well.
My Library as Borrower. This analysis presents all WorldCat Resource Sharing requests submitted by your library, via the staff Workform or the Direct Request Workform.
My Library as Lender. This analysis presents all requested items that are physically or electronically shipped from your library.
Circulation Analysis. This analysis shows how your library’s collection is used within your local community. Data from your library must be sent to OCLC to activate this analysis.
