While geographic search filters exist, few of them are validated and there are currently none that focus on Germany. We aimed to develop and validate a highly sensitive geographic search filter for MEDLINE (PubMed) that identifies studies about Germany. First, using the relative recall method, we created a gold standard set of studies about…

This paper explores possibilities for marrying data visualization to online archival finding aids, which have continually suffered from usability issues in their long history. This paper describes a project in which two different data visualization models were built to replace sections of an archival finding aid. Users were then shown the models,…

Discovery layers provide a simplified interface for searching library resources. Libraries with limited finances make decisions about retaining indexing and abstracting databases when similar information is available in discovery layers. These decisions should be informed by student success at finding quality information as well as satisfaction…

An unprecedented amount of information encompassing almost every facet of human activities across the world is generated daily in the form of zeros and ones, and that is often the only form in which such information is recorded. A good fraction of this information needs to be preserved for periods of time ranging from a few years to centuries.…

Discusses various categories of software that can be applied to the development of in-house databases on microcomputers, and describes the use of a general purpose package with a procedural language to design a small indexing system called Revelation. The description covers data storage and maintenance, database design, file searching, and system…

Describes a scalable, parallel, relational database-drive information retrieval engine. To support portability across a wide range of execution environments, all algorithms adhere to the SQL-92 standard. By incorporating relevance feedback algorithms, accuracy is enhanced over prior database-driven information retrieval efforts. Presents…

A project at Brown University has developed a set of application and system software that provides access to a database of Classical Greek literature which is stored on a CD-ROM. Information on the origins of the project is provided and the technical development of the system is described in detail, including the creation of Classical Greek fonts,…

Describes the design and functions of a technical library database maintained on a mainframe computer and supported by the SPIRES database management system. The topics covered include record structures, vocabulary control, input procedures, searching features, time considerations, and cost effectiveness. (three references) (CLB)
