Monograph holdings

Monograph holdings

Name:  Monograph holdings

Can apply to:  Books

Metric definition:  The number of libraries that own (or hold) a book.

Metric calculation: Holdings counts are derived from national or international union library catalogues, such as OCLC WorldCat.  The holdings count is calculated as the number of unique libraries that own a copy of a book.

Data sources:  Library book holdings as represented in union catalogs.

Appropriate use cases:  Books may produce benefits and impacts that aren’t well captured by conventional bibliometrics, such as citation counts.  Monograph holdings can be used to demonstrate a book’s perceived potential to meet user, teaching, and research needs.

Limitations:  Monograph holdings counts and contextual data, such as the type of libraries that own a book, do not reveal how, if and how often, and by whom a book is used.  Research shows that the use of academic library collections is driven by a small percentage of content.  Moreover, monograph holdings provide an incomplete understanding of historical impacts on such areas such as teaching as research, because less current materials are often weeded from library collections.

Inappropriate use cases:  Monograph holdings are not a direct measure of usage, research quality, or impact.

Available metric sources:  Possible sources include WorldCat, Copac, World Bank and IMF collections, PlumX, and various national and regional union catalogs.

Transparency:   In all of the sources in which monographs holdings data are available, one can trace the details of each library’s ownership information.

Website:  N/A

Timeframe:  Monograph holdings data reflect current library book collections, though books of any age will be reflected.
