With GreenGlass, you can:
GreenGlass offers collection visualization tools with optional data overlays to give you new insights. It also provides:
- A multi-faceted query builder for developing preservation and withdrawal scenarios
- Online lists of items that match the parameters of any query with GreenGlass deselection metadata
- Actionable lists that can be exported to Microsoft Excel
- Enhanced searching on subjects and call numbers to allow subject specialists more control over list building and collection analysis
- Collection segmentation through the ability to search on multi‑edition titles, possible duplicates, and multi‑volume sets
Your GreenGlass database contains:
- Your library’s bibliographic and item-level data with live links to your OPAC
- Your library’s usage data, including circulation, re-shelving counts, and reading room loans
- WorldCat holdings data for your peer libraries, your state, your country, and the world
- HathiTrust Digital Library holdings, including both public domain and in-copyright material
- CHOICE Review and CHOICE Outstanding Academic Title flags
- Customized title protection rules
Adapting old stacks to new spaces for study or collaboration can actually extend your reach to users and rejuvenate your community. Intelligent deselection ensures that you establish appropriate criteria for your library's weeding or shared print projects.
Our process for supporting your deselection project
Step 1: Hold a planning session to set goals for your project.
Step 2: Upload your catalog data to our data center. You can send us a catalog extract via FTP.
Step 3: Cleanse and normalize your catalog data. During this step, we will:
- Identify and fix anomalies
- Look up OCLC numbers as needed
- Map data to OCLC database fields
- Identify and report data remediation opportunities
Step 4: Match catalog records to external data sets. Data sets include:
- Other library data sets (in group projects)
- HathiTrust Digital Library
- Authoritative title lists
Step 5: Load data into the GreenGlass web application.
Step 6: Analyze the collection and model scenarios with GreenGlass. OCLC staff can perform custom analysis as needed.
Step 7: Produce withdrawal and preservation candidate lists.
Step 8: Review lists and edit criteria. As you adjust criteria—for example, by subject area or location—you'll become more comfortable with criteria you choose.
Step 9: Modify or approve withdrawal and preservation lists.
Step 10: Transfer books and update catalog records. Common resolutions include:
- Transfer books to storage facility or archive
- Recycle, donate, or discard books
- Update catalog records in batch
- Update your OCLC holdings through batch processing
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.
- 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 vs. "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
Shared print projects involve working with data from multiple libraries. The size of a group project can vary from as few as two or three libraries up to several dozen. The complexity of a project will vary depending on its size, on the participants’ previous history of collaboration, on the consistency of participants' respective data management practices, on the scope of the project, and other factors.
Group projects likely involve the following components:
- Planning meeting(s): At the outset of a project, it is essential to bring together key players from each library to develop a project scope, strategy, and timeline. This can be done in person or via conference call, and it typically involves project leaders, systems librarians, representatives from collections, and people who knows the data well (often catalogers).
- Data delivery: Each participant library will provide bibliographic, item, and circulation data for all of its in-scope monographs. OCLC then filters, cleanses, and normalizes this data.
- Group data set: We then compile all of the normalized data from participant libraries into a single database and compute various group-level tallies and matches. At that point, the group-wide data set is loaded into GreenGlass Group Functionality.
- Scenario development: In GreenGlass Group Functionality, you can model and discuss an unlimited number of group-wide retention scenarios. GreenGlass constructs retention scenarios from a wide array of parameters, including archiving thresholds (number of copies to retain), publication years, usage levels, and overlap tallies. Many combinations are possible, and developing scenarios that balance risk and yield appropriately is perhaps the most important task in any shared print project. These modeling exercises will help inform your shared retention agreements and will improve each library’s understanding of what can be safely deselected and what must be retained.
- Allocation of retention commitments: Once criteria are finalized and the group has achieved consensus on the retention scenario that will be adopted, we allocate retention commitments to each of the member libraries. In group projects, deselection benefits and responsibilities must be shared equitably, or at least in some manner agreed by the group. Deciding which libraries may withdraw and which must retain certain titles depends on a number of variables, including how many copies the group seeks to retain, which library holds which titles, the size of the collections, space needs, and other factors.
- Retention commitments loading to GreenGlass: In preparation for participants to take local action, each library’s GreenGlass account is updated to reflect the group’s retention agreement. Libraries can then generate lists of items that they are responsible for retaining and corresponding lists of items that are safe to weed.
- Ongoing data management: Although new titles are acquired each year, circulation continues to occur, and other libraries adjust their collections. Most groups find that their final data set can serve for up to two years without modification.
Our role in group projects can vary, but our key priorities include:
- Managing the data: We validate, normalize, augment, and compile the group data to make it as comprehensive and reliable as it can be.
- Providing tools to enable the group to interact with its data: We have created GreenGlass Group Functionality specifically for shared print programs to assist with visualization, modeling, communication, and prediction.
- Ensuring project success: We convene and facilitate meetings, make presentations in person and via webinar, help communicate with stakeholders, support project managers, run custom queries and reports, and do whatever else is needed to achieve your group’s objectives.
GreenGlass Group Functionality
GreenGlass Group Functionality employs visualizations and modeling tools that allow groups of libraries to:
- Understand their shared 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 monograph collections knowing that long-term access to the content has been assured
