ABSTRACT
The National Guideline Clearinghouse (NGC) is a resource created to provide access to and summaries of evidence-based clinical practice guidelines from around the world. It is freely available online at <http://www.guideline.gov>. Currently maintained jointly by the U.S. Department of Health and Human Services and the Agency for Healthcare Research and Quality (AHRQ), the database has grown significantly since it was last reviewed in the Journal of Electronic Resources in Medical Libraries in 2007. This column will discuss the website in its current iteration and highlight features that have been updated as well as new features not previously available.
