See how GreenGlass supports your library's strategic initiatives
Responsibly draw down your print monographs and serials to transform valuable library space
Informed deselection ensures that you establish appropriate criteria for your library’s weeding or shared print project. GreenGlass enables libraries to carefully manage the drawdown of low-use print titles while supporting shared print archiving efforts. GreenGlass combines local circulation and item data with WorldCat holdings, HathiTrust Digital Library holdings, and authoritative title lists. The result: cost-effective, evidence-based decisions that allow libraries and groups to reclaim valuable physical space while protecting the scholarly record.

Our process for supporting your deselection project


Accelerate your shared print management efforts
Academic and research libraries around the world are implementing programs to share the responsibility and costs of maintaining print collections. Several factors are driving this change, including:
- A growing shift in scholarly attention from print to electronic formats means that low-use retrospective print collections are perceived to deliver less value.
- Competing demands for library space favor teaching, learning, and collaboration versus "a warehouse of books".
- The number of institutions with both the mandate and the capacity to support long-term print preservation is shrinking.
- As the return on investment in local print collections diminishes, libraries seek to externalize print operations to shared repositories.
We support shared print initiatives of all sizes, whether conducted individually or across a group of libraries.

Components of a group project
Our role in group projects can vary, but our key priorities include:
Examples of shared print projects for groups
Collaborate using Group Functionality
GreenGlass Group Functionality employs visualizations and modeling tools that allow groups of libraries to:
- Understand their collective collection with respect to overlap, subject dispersion and usage
- Experiment with various retention scenarios, and estimate the impact on each participant library
- Commit to specific retention agreements, with confidence in and comprehension of the outcome
GreenGlass Group Functionality employs query tools and item lists that allow individual libraries to:
- Protect the right books – and thereby share responsibility for the collective collection
- Downsize print collections, knowing that long-term access to the content has been secured
