the search box. • Enter the citation

elements you have – author, title words,

journal, volume, year, etc.

– example: dixon pharmacotherapy 2016

• Use the Advanced Search to search by journal name.


25

Searching for Author Author Search:• Multiple authors may publish

under the same name• Best practice: start with last

name and initials– For example: dixon dl

(Dave L. Dixon) – No need to tag, capitalize

or punctuate• Avoid searching using full

author names• Not all PubMed records include

full author names• Using full first names may miss

articles where only initials were provided
