PubMed has moved its Limits feature to the results page to make them more visible and accessible. You may now select limits for your search on the Filters Sidebar on the left of your results page. Searches can be limited by publication date, species, article type, and language. Other popular limits such as sex and age are available by clicking the Choose additional filters link at the top or bottom of the list. Remember to click Clear all under the Results number or near the bottom when you are done or your limits will remain in effect for your future searches. Several examples of ways to use these limits are available.
