## What is PubMed Central?

- PubMed Central (PMC) is the U.S. National Library of Medicine's digital archive of peer-reviewed, primary research articles from life science journals
- Launched Feb 2000
- In six years has grown to 230 journals, 596,000 articles
- Unique IP addresses: 2 million / month
- Articles retrieved / month – HTML full text, PDF, or scanned article summary: 7.65 million
- Total page views / month, incl. searches: 11.45 million

## PMC Philosophy & Function

- A logical extension of NLM’s general mandate
- Digitize journal back issues to create a full electronic record of a journal
- Provide free and unrestricted access to PMC, which ensures durability and utility of the archive as technology changes over time
- Follow in the footsteps of other major NCBI resources
- Integrate the literature with other valuable information resources in the database family – PubMed, Nucleotide, etc.

## What’s in PMC?

- Electronic content representing current journal issues
- Small subset is Open Access
- Digitized Print content for older material (Back Issue Digitization Project)
- NIH Manuscripts (NIH Public Access Policy)
- Wellcome Trust Manuscripts

## PMC and Public Access

- The Public Access Policy requests that investigators funded by the National Institutes of Health (NIH) submit an electronic version of their final, peer-reviewed manuscripts upon acceptance for publication to the NIH National Library of Medicine's PubMed Central (PMC).
- To facilitate the submission process to PMC, NIH has developed the NIH Manuscript Submission (NIHMS) system (_[http://www.nihms.nih.gov/](http://www.nihms.nih.gov/)_), a password-protected, Web-based system.
- Currently 2500 NIH Manuscripts in PMC
