Total recorded uses: Shows number of collection items and how many times they’ve been circulated. Colored overlays illustrate various breakdowns such as presence in HathiTrust that can help determine weeding candidates.

Year published: Depicts number of collection items by publication date. Color coding indicates number of circulations. The left-most column serves as a catch-all for items published before 1920.

Subject distribution: This shows the distribution of a library’s collection by high-level subject categories (US Library of Congress classes), data that is rarely seen in this graphed format.

GreenGlass for Serials: The top graph illustrates the entire publication run of a serial title in WorldCat holdings; the second presents the library’s local holdings for that title.

Holdings in the US: This chart presents a library’s holdings relative to how commonly held they are by other US libraries. The bar graph progresses from least-held on the left to most often held on the right.

Group overlap: Library groups here can compare collections, with each bar representing a group member with a shared print program. Length of the bar indicates size of the collection, while color coding shows which materials are held uniquely or more commonly.

HathiTrust: This graph shows each library in a group or consortium, and what percentage of their materials are in HathiTrust, both in copyright and in public domain.

Decision support for serials

Serials analysis and management can be time-consuming and complex as it often requires evaluation of a much wider range of information than monographs. GreenGlass is a data-driven decision support tool that empowers your library to take local action on its print serials by leveraging collection data from many libraries. It works with all major ILSs and helps make decisions for your entire system or specific departments.

For serials projects, GreenGlass:

Includes data on publication status, date ranges, rarity, out-of-date status, and more
Helps define goals for retention, deselection, and other collection management priorities

Identifies duplicate holdings in archives like JSTOR and HathiTrust, as well as holdings archived by shared print programs

Improves both the efficiency and value of serials collection activities
Recognizes serials data clean-up opportunities
