Related Articles: PubMed

The related articles link in PubMed retrieves a pre-calculated set of citations that are similar to or related to the original citation.

Some of the advantages of related articles are that it's a rapid, easy way to identify like citations. You can also pick up citations that other strategies might miss. All in all, a good way to quickly find relevant citations.

Some disadvantages are that it is not comprehensive. Any limits you applied to your original search will be not be applied to the pre-calculated related articles. By using History you can reapply limits (e.g., english) but this removes the ranked order and may remove citations that are most relevant. You will also notice that relevancy can drop off quickly. And, in order to use this feature, you need to start with a relevant citation.

The bottom line is that you should definitely add 'related articles' to your arsenal of strategies as you search for information.
