OSTI creates and deploys web-based information products to accomplish its mission. One way to measure the success of this approach is to use web metrics to gauge and analyze the usage of the information we disseminate via our web- based products.
An "information transaction" is the largest and most broadly defined web metric we track at OSTI. We define an information transaction as a discrete information exchange between an information patron and OSTI's suite of web-based information services. An information transaction occurs when our web servers deliver information to satisfy a user's request. Requests can take a variety of forms. Sometimes a user's request might be a search of a product such as Science Accelerator that brings back a hit list. Following up on this information transaction, a user might click on an item in the hit list to call up a single bibliographic citation delivered via a component database of Science Accelerator such as the Information Bridge or Energy Citations Database. Next, the user might call up the full text of a technical report. Another type of information transaction would occur when a user requests tens, hundreds, or thousands of bibliographic citations via our OAI or MARC xml services.
In 1994, OSTI launched and hosted the first DOE web home page. From this small web presence, OSTI served 300,000 information transactions. In FY 2008, OSTI served over 84,000,000 information transactions, a 28,000% increase.
While information transactions are of great use and give us a great metric relative to information dissemination, it is useful to more...Read more...
OSTI now offers librarians and others, free of charge, the opportunity to download records of DOE research and development (R&D) information in MARC (MAchine-Readable Cataloging) format. Records are available for the full-text reports contained in the Information Bridge. By using OSTI's MARC records download librarians can easily expand access to a variety of scientific research straight from their online library catalogs.
OSTI MARC Records are derived from existing Information Bridge records. There are currently over 170,000 records in the Information Bridge. Options for downloading records include subject category, year and OSTI ID number.
Information Bridge provides free public access to full-text documents and bibliographic citations of DOE research report literature. Documents are primarily from 1991 forward and were produced by DOE, the DOE contractor community, and/or DOE grantees. Legacy documents - including U.S. Atomic Energy Commission (AEC) documents dating back to the 1940s - and their MARC...Read more...
