Pub Med Central Update Jennifer Jentsch Medical Library

Pub. Med Central Update Jennifer Jentsch Medical Library Association Conference May 2006

What is Pub. Med Central? • • • Pub. Med 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 – Pub. Med, 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’s Archives Recent & new electronic content • Represents roughly 40% of PMC content • Keep PDF, full-text XML, original images, supplementary material • XML preferred for archiving: - technology-independent and portable - allows for richer linking and automated text analysis Back issues (print only) • Now approximately 60% of PMC content • Print journals scanned cover to cover – from volume 1 • Create and archive high quality PDF with true reproduction of figures / images • OCR text used to do full-text searching and build list of linked reference citations

Open Access Journals in PMC • Open Access Journals in PMC: – Bio. Med Central Journals – Amphibian and Reptile Conservation – Biological Procedures Online – Journal of Biomedicine and Biotechnology – Journal of Insect Science – Nucleic Acids Research – PLo. S Biology and Medicine – Preventing Chronic Disease • In October 2003, PMC began accepting individual open access articles from journals that do not participate in PMC on a routine basis. – Science – Biological Chemistry

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 Pub. Med Central (PMC). • To facilitate the submission process to PMC, NIH has developed the NIH Manuscript Submission (NIHMS) system (http: //www. nihms. nih. gov/), a passwordprotected, Web-based system. • Currently 2500 NIH Manuscripts in PMC

PMC Content Sources Regular PMC Participation (since 2000) • Formal agreement between NLM and publisher • Journal may delay free access up to a year or more • Copyright is retained by publisher or author • Deposits are permanent • Journal may stop depositing new material but may not withdraw material already deposited NIH Public Access Policy (May 2005) • Requests NIH grantees and intramural researchers to deposit final manuscript of paper accepted for publication • Author specifies PMC release date – up to 12 months after publication – subject to publisher’s copyright policy

Manuscript in PMC • Distinctive banner with NIHPAspecific links • Citation for MS and for published article • Link to published article at journal site • Otherwise, looks like other PMC articles

PMC – Recent Developments • Springer ‘Open Choice’ and Blackwell ‘Online Open’ articles now coming in to PMC • Also working with OUP ‘Oxford Open’ • Detailed tagging guidelines released for NLM Journal Publishing DTD • Library of Congress and British Library are adopting NLM Journal DTD as a standard for tagging journal articles

PMC in the Future • PMC International – PMC-in-a-box for quick setup of a reliable mirror – Tested by UK (Wellcome Trust), Italy (Italian National Research Council) and S. Africa (National Bioinformatics Network) – Also working with British Library, China and Japan • PMC Help as book on NCBI Bookshelf
