My Comparisons allows you to view comparisons for your library, go to the Benchmarking and Unique/Shared Titles pages, and export the Comparison Title List.
From the My Comparisons tab, hover over the information icon () beside a Comparison Name to view the following summary information:
The date when the comparison was last updated
The date when the comparison is set to expire
The institutions that are included in the comparison
Benchmark comparisons provide insight into the strengths and gaps within your collection against the collections of the selected comparisons. A benchmark comparison indicates the titles that are unique to your collection, the titles you share with other collections in the comparison, and titles that the comparison group owns but are not part of your collection.
When you export a comparison title list, the system generates a spreadsheet containing the title-level collection data from the most recent version of the comparison you have built. It lists all of the titles that are in your library and the comparison institutions. You can download this spreadsheet and keep it for your records.
Unique/shared title lists are used for weeding and retention activities. When you create a unique/shared title list, you are creating filters that refine the results of your comparison. The unique/shared title list can reflect the titles that are unique to your collection, only titles that are shared with the comparison group, or both.
You can refine a WorldCat comparison for weeding and retention activities. When you refine a WorldCat comparison, you are applying filters that refine the results of your comparison. This refined comparison reflects the titles that are unique to your collection and the titles that are shared with WorldCat.
