OCLC Research is a busy place and from time to time we retire our projects and activities. This page lists activities that are no longer so active, just in case you want to dig into the past a little bit.
Python scripts that demonstrate how short compliant Open Archives Initiative-Protocol for Metadata Harvesting can be. Includes a harvester, a repository, and a readme file.
Data mining of the one million MARC records for archival materials in WorldCat will provide a systemwide overview of descriptive practice and enable recommendations for more effective description and discovery.
Collect query logs, Web logs, and various web analytics; evaluate their usefulness for research about how researchers use archival cross-searching networks and other tools that archives use to publish their finding aids.
A document-sharing site that provides a single, secure location where lending libraries can place requested PDF and TIFF articles and library users can retrieve articles or book chapters obtained for them via interlibrary loan. Article Exchange adds convenience, security and enhanced copyright compliance to online article sharing through interlibrary loan.
This research project explored using library holdings data in WorldCat to calculate audience-level indicators for books represented in the WorldCat database, based on the types of libraries that hold the titles.
Identification of barriers to implementing Encoded Archival Description (EAD) and practical suggestions for getting around those obstacles.
Got a book title from an online bookseller? Check whether your local library has it.
This data mining project sought patterns in the worldwide book publishing industry, as reflective of different cultures’ literary heritage. It stemmed from UNESCO interest in statistical traces of cultural diversity.
This work sought to establish best practice for the disposition of print journals available in electronic form – i.e. when it is most appropriate to retain print back files on campus, when to store offsite, and when to deaccession entirely.
This activity looked at existing archival collections assessment activities across institutions, put them into context, and described the range of deliverables from these activities.
The DeweyBrowser was a prototype system for searching and browsing millions of WorldCat® records classified by the Dewey Decimal Classification® (DDC®) system.
This activity conducted research to provide evidence to inform more efficient and effective MARC metadata practices.
Develop use case scenarios for academic libraries and scholars, archivists and archival users, and institutional repositories describing their needs to uniquely identify and distinguish persons and organizations, then define the characteristics, functions, and data attributes of a cooperative "Identities Hub."
Facilitate refinement, publication and dissemination of EAC.
This project attempts to mitigate the risk aversion that is related to rights management and special collections, often interfering with our mission of providing access to those collections.
An investigation into the incentives and strategies for deep and transformative collaboration among libraries, archives and museums (or LAMs).
In order to centralize information about stolen and missing rare books and special collections, this working group developed a procedure to “tag” records in WorldCat.org. The tagged records are then automatically fed to a blog, missingmaterials.org. Simultaneously, holdings are set in WorldCat, in order to alert prospective buyers and sellers.
This project created tools supporting standards-based data sharing in the museum community, and provided insights into the characteristics of large aggregations of museum descriptions.
The NDLTD Union Catalog project focused on thesis metadata via the Open Archives Initiative's Protocol for Metadata Harvesting (OAI-PMH). This was a lightweight protocol for moving or sharing metadata that allowed synchronization of loosely coupled databases and mandates XML Dublin Core as the default metadata format.
OAIHarvester was an early attempt to write an OAI-PMH client application. It was replaced by the OAIHarvester2 project.
The OAIHarvester2 Open Source Software (OSS) project is a Java application that provides an OAI-PMH harvester framework.
OOMRef-J is a Java implementation of ANSI/NISO Z39.88 – The OpenURL Framework for Context-Sensitive Services.
The ANSI/NISO Z39.88-2004 (OpenURL) Registry identifies and defines the set of approved components for use in the OpenURL Framework.
The PREMIS Maintenance Activity was set up by the Library of Congress to serve as a permanent Web home for the Data Dictionary, its associated XML schemas, and other resources. The PREMIS Data Dictionary is the international de facto standard for preservation metadata.
An experimental service to provide authority control for publisher names in bibliographic catalogs.
An investigation into the digital capture methods of those who are making progress digitizing special formats at scale.
This project involves issuing a provocative call to action, urging academic libraries to take a more significant role in their institution's mission to support research.
OCLC Research conducted a small scale experiment to explore the effectiveness of tools and techniques for bringing offline descriptions to the open Web.
A project to create guidelines for the implementation of single search for local aggregations of LAM collections.
This working group addressed workflow and policy issues arising from digitizing (and copying) materials from special collections.
A study of the role of research libraries in the higher education research assessment regimes in five countries.
Create, print and save custom Tag Clouds for Web pages or other textual data.
This project provided Web-based services for controlled vocabularies.
VIAF explores virtually combining the name authority files of national level authority files into a single name authority service.
A cloud-based Library System for small libraries that includes Circulation, Cataloging, Online Patron Access Catalog (OPAC), and the Library Web Site.
This activity produced a data visualization prototype that presented a graphical and interactive interface to three OCLC Research projects: OCLC WorldMap, OCLC Audience Level, and the Publisher Name Authority File.
View data relating to libraries and collections in a map-based visual interface.
