Options Considered
Alma Analytics offers the following options. ARL instructions for title counts say :
Report the total number of titles managed and maintained by the library that are cataloged and made ready for use.
Deduplicate titles by counting multiple copies of the same manifestation as one title.
Identical content in different formats should not be deduplicated, and each format should be counted as a different title. For example, a serial title available in print, microform and online would be counted as three titles.
Count different editions and versions of the same work as separate titles since they denote depth in the collection.
Counting the 245 field when the library provides stewardship for those resources may be sufficient.
OptionsAlma Options | Notes | Option 1 - |
|---|---|---|
Title Normalized, separated by format | This undercounts unique titles because works with different authors and editions are not distinguished. | |
Option 2 - Title Author Combined and Normalized, separated by format | This undercounts unique titles because works in different editions are not distinguished | |
Option 3 MMS ID | This overcounts unique titles. |
