Unlike Internet search engines, Medline search tools search over 4600 biomedical journals and will display your results in a chronological order with the most recently indexed article appearing first. Although this method for arranging results may make it more challenging to find a relevant article, it allows you to scan the recent publications in your area of interest by running your search at regular intervals. Most of the Medline search engines will allow you to narrow your search to particular journals, age groups and article type among other things.
My favorite free Medline search tool is PubMed (http://www.ncbi.nlm.nih.gov/PubMed/). PubMed allows you to save your search strategies as “favorites” or “bookmarks” in your browser allowing you to check for recent articles with a single click of a mouse. Instructions explaining how to do this are available on-line. Another method is to use the “Cubby” feature. I have not used it but I understand it is an easy method for saving and retrieving searches.
Once again though there are multiple tools that can be used to search Medline, it is best to become familiar with one of them so that you may refine your search techniques which will increase your efficiency.
