NLM Gateway Transitioning to New Pilot Project Site

[Editor's note: The transition of the NLM Gateway at http://gateway.nlm.nih.gov was completed on December 7, 2011.]

On December 1, 2011, the NLM® Gateway will transition to a new pilot project from the Lister Hill National Center for Biomedical Communications (LHNCBC). The current version of the NLM Gateway provides search access across multiple databases; however, all but one of these databases is available from other NLM sources, and most users of those databases search them directly and do not use the NLM Gateway. Only one database, Meeting Abstracts, is uniquely located on the Gateway system. Although NLM has invested in and supported the NLM Gateway for eleven years, based on current budget limitations and the results of evaluations of the use of NLM Gateway, the Library has recently decided to discontinue this service, as currently configured, and transition to a new pilot project site.

The new site will focus on two databases: Meeting Abstracts and Health Services Research Projects in Progress (HSRProj). A forthcoming NLM Technical Bulletin will provide more information on this new service from the LHNCBC. Once the new pilot system is available in December, the current Gateway URL will redirect any visitors to the new Web site. The Meeting Abstracts database will still be unique to this site, while HSRProj will continue to be accessible from its home site.

The Meeting Abstracts database contains selected abstracts from meetings and conferences in the subject areas of AIDS, Health Services Research, and Space Life Sciences. The last update to the Meeting Abstracts Database is anticipated to be the addition of the 2010 18th International AIDS Conference, which is expected to be loaded in the fall of 2011. After this addition, the Meeting Abstracts database will still be accessible, but no new data will be loaded.

All of the other resources currently accessed through the NLM Gateway will be available through their individual sites (see Table 1). The home sites for these systems are listed on the NLM Databases & Electronic Resources page. This directory of resources is easily located by clicking on the "All NLM Databases" link in the Databases column on the NLM homepage.

If you are accustomed to the NLM Gateway cross file searching function you may want to try using the cross database features provided by TOXNET® and by the NCBI Entrez system.

The search box on the TOXNET homepage offers a cross database search function for the databases in the Toxicology Data Network (see Figures 1 and 2).

The NCBI global query feature on the NCBI homepage provides a cross database search feature for all of the Entrez databases (see Figures 3 and 4). Selecting "All Databases" in the search box will return a summary search page identifying possible results across all of the NCBI Entrez databases, including PubMed, PubMed Central, BookShelf, NLM Catalog, and the genetic and protein databases such as Gene, OMIM, BLAST, dbGaP, and others.

You can simply bookmark the Web page http://www.ncbi.nlm.nih.gov/gquery to access the global query search feature. However, going to the NCBI homepage may be the easier way to access this function; the NCBI logo on the top left corner of any Entrez-based system links to the NCBI homepage.
