NLM® Gateway Searches the NLM Catalog

NLM® Gateway Searches the NLM Catalog. NLM Technical Bulletin. 2004 Sep–Oct;(340):e1.

September 16, 2004 [posted]

In mid-September 2004, NLM Gateway introduced access to the NLM Catalog for searching bibliographic data for books, journals, audiovisuals, and other materials.

Changing the access to NLM's bibliographic data from LocatorPlus to the NLM Catalog enhances Gateway's searching and retrieval. Enhancements include author searching, automated term mapping, MeSH explosion, searching MeSH terms that are major topics, searching MeSH heading/subheading combinations, searching date ranges, and no limit on the number of items retrieved.

In addition, there are changes in the data fields available to the user through the Gateway. Many new fields have been added (e.g., Indexing History), some fields have been merged (e.g. Absorbed, Absorbed in Part, Continues, and Continues in Part are all labeled "Continues"), and two fields have been eliminated (Journal Title Code and Publisher Address).

Search results are displayed in the Books/Serials/AVs category in reverse publication date order, latest to earliest. There are two exceptions: the most recent week's additions will appear at the top and records that do not contain a date of publication sort at the bottom.

For general information on how to search the NLM Gateway, please see Gateway Help and the Gateway FAQ.
