Search fields/accesses Affiliation [AD]: Harvard Medical School[ad] Author [AU]: Leon DA[au] Issue [IP]:The number of the journal issue in which the article was published. Journal Title [TA]: J Biol Chem[ta], Journal of Biological Chemistry[ta] Language [LA]: eng[la] MeSH Major Topic [MAJR] MeSH Terms [MH]
Search fields/accesses Pagination [PG] Publication Date [DP]:The date that the article was published. Format: YYYY/MM/DD [dp], “ last X days ” [dp], “ last X months ” [dp] o r “ last X year ” [dp] Publication Type [PT] : review[pt] Title [TI] Title/Abstract [TIAB] Volume [VI] : The number of the journal volume in which an article is published. EC/RN Number [RN] Number assigned by the Enzyme Commission (EC) to designate a particular enzyme or by the Chemical Abstracts Service (CAS) for Registry Numbers, e.g., 1-5-20-4[rn] A RN – a substance name An ISSN – a journal name
For some names, it is necessary to distinguish which name is the last name by using a comma following the last name. In this example, we are searching for James Ryan, rather than Ryan James. See the following result:
For a simple way to find author names in PubMed, use the Advanced Search page.
Boolean operators The logical relationships among search terms, AND, OR, NOT, must be entered in UPPERCASE letters. AND Used to retrieve a set in which each citation contains all search terms Example: boat AND sail AND is the default operator used in PubMed. If you don’t include operators in your search, PubMed will automatically use AND between terms The retrieval is only the overlap of the results for each term – those record in which both terms appear. boat sail
Boolean operators NOT Retrieves a set from which citations to articles containing specified search terms following the NOT operator are eliminated. Example: boat NOT sail The retrieval is a portion of the total retrieval for boat, - that portion not including the term sail. boat sail boat sail OR Used to retrieve a set in which each citation contains at least one of the search terms Example: boat OR sail Use OR when you want to pull together articles on similar topics
Limits function in Advanced Search Page Limits allow you to set commonly used parameters for your query, which may result in more relevant retrieval.
