Summary
The National Library of Medicine (NLM) launched the NLM Gateway, a metasearch engine for accessing multiple NLM databases simultaneously. This tool provides a unified search experience across diverse information categories for users.
Area of Science:
- Biomedical Informatics
- Health Information Science
Background:
- The U.S. National Library of Medicine (NLM) is a major source of biomedical information.
- Accessing diverse NLM resources often required searching multiple individual databases.
Purpose of the Study:
- To introduce the NLM Gateway, a novel metasearch engine.
- To provide a consolidated search interface for NLM's retrieval systems.
Main Methods:
- Developed a metasearch engine accessible via gateway.nlm.nih.gov.
- Integrated multiple NLM retrieval engines into a single search platform.
Main Results:
- Users can perform a single search across various NLM databases.
- Results are categorized into journal citations, books, audiovisuals, consumer health, meeting abstracts, and other collections.
Conclusions:
- The NLM Gateway simplifies and enhances access to the NLM's comprehensive information resources.
- This tool streamlines the process of discovering biomedical and health-related information.
