NLM Gateway Transition to Pilot Project Site

The NLM® Gateway transitioned to a pilot project from the Lister Hill National Center for Biomedical Communications (LHNCBC) in 2011. The previous version of the NLM Gateway provided 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 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 decided to discontinue this service and transition to a pilot project site.

The pilot NLM Gateway focused on two databases: Meeting Abstracts and Health Services Research Projects in Progress (HSRProj). 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 was the addition of the 2010 18th International AIDS Conference. The Meeting Abstracts database is still accessible, but no new data has been loaded.

In May 2014, Health Services Research Projects in Progress (HSRProj) was retired from the NLM Gateway. HSRProj is accessible through the portal site HSR Information Central ( and directly at

All of the other resources previously accessed through the NLM Gateway are 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 & APIs" link in the Databases column on the NLM homepage.
