Searching the MEDLARS file on NLM and BRS a comparative study

Area of Science:

• Medical Informatics
• Library Science
• Health Sciences Information Management

Background:

• The MEDLARS database is a critical resource for health sciences information.
• Access to MEDLARS is available through multiple platforms, including the National Library of Medicine (NLM) and Bibliographic Retrieval Services (BRS).
• Understanding the differences between these access points is crucial for efficient information retrieval.

Purpose of the Study:

• To compare the MEDLARS database as accessed via the National Library of Medicine and Bibliographic Retrieval Services (BRS).
• To identify and highlight major capability differences between the NLM and BRS systems for accessing MEDLARS.
• To provide information supporting decisions regarding the dual availability of the MEDLARS database in health sciences libraries.

Main Methods:

• A comparative analysis of the MEDLARS database on two distinct platforms.
• Presentation of findings in a chart format for clear comparison.
• Identification of key functional and capability distinctions between the systems.

Main Results:

• Significant differences in capabilities exist between the National Library of Medicine's MEDLARS system and the Bibliographic Retrieval Services (BRS) version.
• The comparative analysis provides a clear overview of these distinctions.
• The study details specific functional variations relevant to users and administrators.

Conclusions:

• The distinct capabilities of the NLM and BRS systems justify their dual availability for health sciences libraries.
• Information professionals and administrators can use this comparison to optimize database access and acquisition strategies.
• Choosing between or utilizing both systems depends on specific user needs and institutional requirements.
