Principles for Searching PubMed

PubMed - www.pubmed.gov - is an "Index" to about 4800 biomedical journals published worldwide. This Index is compiled in the National Library of Medicine, USA. When you search PubMed you get a list of "References" (also called a Bibliography) of what is published in these journals. Each reference or bibliographic record will mention the following
  • Author/s of the article
  • Title of the article
  • The journal in which the article is published
  • The year in which it was published
  • The volume number, issue number and page number of the article
  • Most articles will also have an abstract, but not all do
It is important to note that 
  • PubMed does not provide the full text of the article, 
  • PubMed will link a reference to the journal website right to the article 
    • If the article is available online and 
    • If the publisher has arranged for the link
So - you should never say that you found an article IN PubMed, but you found it THROUGH PubMed

PubMed is a huge database (approximately 20 million references). Most people tend to search it the way they search Google - using plain text. While free text search does work in many cases, learning a structured approach to searching PubMed will help save huge amounts of time. 

This Section provides Four Fundamental Principles that form the foundation for searching any bibliographic database. If you understand these, you will find these principles useful for majority of databases We also show you one feature that uses these principles
