PubMed can be accessed from the Dykes Library site at http://library.kumc.edu/. Look for PubMed in the left panel. Always start by going to the Library website and clicking on the PubMed link from the main page.
Once you are in PubMed you will see a search box at the top of the page. For a basic keyword search, type the word(s) you are searching for in the box, and click Search. PubMed will return results, which can be further filtered by utilizing the Filters on the left side of the page.
