As of August 2016, PMC is home to four million articles! To make this wealth of
full-text content easier to navigate, PMC has rolled out a few updates:
1) Search Result Filters
On all search results pages, you will now see filters
(similar to PubMed’s filters) on the left-hand side that allow you to filter your results by
article attributes, publication date, research funder, and search fields. These filters
replace the Limits page and allow you to more readily:
- find open access articles (PMC has more than 1.35 million open access articles that can
be reused according to their license statements),
- explore PMC’s rich historical content from NLM’s back issue
- browse research supported by PMC-participating funding
organizations (click “Customize” to view additional funder options),
- and much more.
You can now also quickly add articles that are under a 12-month or less embargo in PMC to
your search results by selecting the “Include embargoed articles” filter option under Text
Availability. See the PMC User Guide for
more information on these filters.
2) Reference List Display
Using related article data available in PMC,
articles that cite papers that have been either retracted or named in a Findings of Research
Misconduct issued by the HHS Office of Research Integrity and not yet retracted will now
include a red hyperlink to the relevant notice directly from the article’s reference list.
