As you may have noticed, PubMed changed the way users limit search results. The link for “limits” has been replaced by a “filters” sidebar. This sidebar will function similarly to the way the limits page worked. For example, once filters/limits have been set, they will remain in place for all subsequent searches unless the user turns them off.
One difference users might notice is that filters will not show if they are unavailable or not applicable for a search. For example, if you run a search on a topic where there hasn’t been a meta-analysis done, the option to limit your search to meta-analyses will not be available.
A feature that should be used with caution is the “Text Availability” filter located prominently at the top of the filters bar. Remember that these filters are for people that do not have access to a health sciences library. Students, faculty, staff, residents and fellows of the University of Iowa should avoid these filters and use our InfoLink button instead (which is seen when you access the abstract view). This will ensure that high quality articles are not missed. Remember that University of Iowa affiliates can also take advantage of our free interlibrary loan service. http://www.lib.uiowa.edu/hardin/illa.html
