Networked Computer Science Technical Reference Library
Edward Fox, Jim French, Paul Jones, Kurt Maly, Michael Nelson, and Mohammad Zubair are leading an effort to work toward moving the Networked Computer Science Technical Reference Library (NCSTRL) into a sustainable, Open Archives Initiative (http://www.openarchives.org/) conformant framework.
Virginia's Internet Technology Innovation Center (http://www.internettic.org/) has provided $30K of support that will go largely to shifting NCSTRL into the OAI sphere, through efforts at Old Dominion University, University of Virginia, and Virginia Tech. Paul Jones and the team of ibiblio.org (see http://www.ibiblio.org/) at the University of North Carolina, Chapel Hill, will run the EPrints software (see http://www.eprints.org/) to help in this process. At Old Dominion University, the ARC (see http://dlib.cs.odu.edu and Kepler software (see http://www.dlib.org/dlib/april01/maly/04maly.html) will be used.
The initial work in this process should lead to an OAI-based operation of NCSTRL by October 2001, with four NCSTRL collections in Virginia demonstrating the feasibility of both saving the historical NCSTRL collection and pointing the way for a new paradigm of disseminating Computer Science technical reports. Our aim is to demonstrate that our approach can be linked with related projects -- e.g., the National Science Foundation's National Science Digital Library (see http://www.nsdl.org) and the Networked Digital Library of Theses and Dissertations (see other articles in this issue of D-Lib Magazine) -- and can be expanded to other disciplines as well. For the purpose of fully moving NCSTRL into the OAI world, we will seek further funding.
There should be little impact initially on the operations at most NCSTRL sites, and the service at the NCSTRL web site should provide similar capabilities to what resulted from previous NCSTRL support. Those involved in NCSTRL or otherwise interested in this effort are encouraged to read the proposal about the OAI based Technical Reference library.

Electronic Journals Library - Max Planck Society
The Elektronische Zeitschriftenbibliothek EZB (Electronic Journals Library) offers an effective use of both scientific and academic journals publishing full text articles in the internet.
This service has been developed at the Universitätsbibliothek Regensburg (University Library of Regensburg) in cooperation with the Universitätsbibliothek der Technischen Universität München (University Library of the Technical University of Munich).
All the time, the EZB is being further enlarged .
Meanwhile, 312 libraries and research institutions make use of this service in their daily work.
They collect the titles cooperatively and update the bibliographic data jointly in a central database. For each participating institution, we generate a range of electronic journals adapted to the respective library's requirements. Each member can administer for itself the locally licensed journals and integrate individual user instructions by means of a decentralized specific license administration. Online journals on subscription can therefore be offered within the same system as free e-journals.

This aggregation of metadata and reference images make this repository a valuable tool for searching across many University of Minnesota image collections. IMAGES was developed with the support of funding from the Institute of Museum and Library Services.

Open Video Project
Anticipating a future withwidespread access to large digital libraries of video, a great deal of research is currently focused on many areas related to digital video. Research in these areas requires that each investigator acquire and digitize video for their studies since the multimedia information retrieval community does not yet have a standard collection of video to be used for research purposes.
The purpose of the Open Video Project is to collect and make available a repository of digitized video content for the digital video, multimedia retrieval, digital library, and other research communities. Researchers can use the video to study a wide range of problems, such as tests of algorithms for automatic segmentation, summarization, and creation of surrogates that describe video content; the development of face recognition algorithms; or creating and evaluating interfaces that display result sets from multimedia queries. Because researchers attempting to solve similar problems will have access to the same video content, the repository is also intended to be used as a test collection that will enable systems to be compared, similar to the way the TREC conferences are used for text retrieval.
This repository is hosted as one of the first channels of the Internet 2 Distributed Storage Infrastructure Initiative, a project that supports distributed repository hosting for research and education in the Internet 2 community.

Public Knowledge Project Open Archives Harvester - PKP
