Fact Sheet
The NLM Gateway


NLM® Gateway:

Gateway is "One-stop shopping" for an increasing number of the information resources of the National Library of Medicine (NLM).  It’s targeted to the Internet user who comes to NLM not knowing exactly what is here, or how best to search for it.  A single interface that searches in multiple retrieval systems, Gateway provides a single address, look, and feel.

Gateway Characteristics

The user enters one query that is sent automatically to multiple retrieval systems having different characteristics but potentially useful results. Results from the target systems are presented in broad categories (bibliographic resources, consumer health resources, other information resources) rather than by database.

We expect that users will come to Gateway for an overview scan of NLM's resources. Some will find what they need immediately. Others may find that one resource, such as PubMed® or MedlinePlus®, has information they would like to know more about. They may then choose to go straight to that resource for a more focused search.


Gateway now Accesses:

The basic Gateway search interface is simple. It takes advantage of the capabilities of the retrieval systems it links to, for example, the advanced query parser and the Related Articles and LinkOut functions in MEDLINE/PubMed. Users can set preferences to adapt the interface to their needs, such as specifying which elements of a record they wish to see in the display of results. A "locker" is used to store selected results the user wishes to keep across sessions. The user can download, print, or email results.

The design builds on the strength of the intelligent gateway concept: the ability to offer value-added capabilities the user did not know to ask for. In future versions, links within and across databases will be exploited. Searches in clusters of NLM databases (or in all databases) will be offered.

Current Status

The NLM Gateway was released to the public on October 16, 2000. A comprehensively redesigned version was released on April 4, 2005. New versions are released periodically.
