MedLine Indexing
Subject experts at NLM read incoming articles for inclusion into the database.Identification of the topicsConsult the MeSH to select appropriate terminology to match the topics.The MeSH terms are added to the entry into MedLine along with other information on the article.Using the MeSH terms allows one to be more comprehensive in searching.
MeSH (Medical Subject Headings)
Selected from 19,000 Thesaurus terms
Major headings are indicated as * in MedLine DB
Subheadings-used as qualifiers-assist in narrowing a search.
MeSH (Medical Subject Headings continued)
Advantages of MeSH Structured vocabulary Find relevant articles that may not contain keywords mentioned in title or abstract Eliminates irrelevant records
Disadvantages of MeSH Scientific jargon not covered Human indexers at NLM may not be consistent Not every concept in article can get thesaurus term Lag time between indexing and initial placement in the MedLine database can be long.
OMIM-Online Mendelian Inheritance in Man
A catalog of human genes linked to diseasesBegan by Victor A. McKusick at Johns Hopkins UniversityA good place to start when you want to research a certain disease or biological moleculeThis database is cross-referenced to PubMed and other NCBI-based databases
How to keep a running tab on your favorite subject?
Set up Cubby. An automatic retrieval system that searches PubMed and deposits the literature citations in your own account (there is no charge). Requires a login. Demonstration
