New Search Interface for the NLM IndexCat Database

DuQuette LA, Smith CN. New Search Interface for the NLM IndexCat. NLM Tech Bull. 2014 Mar-Apr;(397):e1.

2014 March 25 [posted]

NLM is pleased to announce the launch of a new user interface for the IndexCat database. Utilizing the IBM® InfoSphere Data Explorer (DE) software, the new interface offers a faster response time to searches; full record displays in search results; and also record sorting and refinements. NLM also uses DE as the search engine for our main Web site, as well as MedlinePlus, MedlinePlus en Español, the Directory of the History of Medicine Collections search engine, and the History of Medicine Finding Aids Consortium. The DuraSpace Fedora platform will be used for storage of the data.

IndexCat simultaneously searches the digitized version of the printed Index-Catalogue of the Library of the Surgeon General's Office; eTK for medieval Latin texts; and eVK2 for medieval English texts; and LocatorPlus. You can link directly to LocatorPlus and, if onsite, can request materials to research in the library.

A post in the NLM Circulating Now blog offers additional information on IndexCat.
