Before the boom: 13 percent of cancer literature is free

March 31st, 2008 by dwentworth

Heather Morrison, who’s been tracking the growth of open access to medical literature, has posted baseline figures for the percentage of literature on cancer that’s freely available online in full text format, pre-NIH mandate:

13% of the literature in PubMed on cancer links to Free Fulltext.
By publication date range:
7% – within last 30 days
10% – within the last year
17% – within the last two years
21% – within the last 10 years

Opening access is the foundation for making the medical literature useful in the digital era, facilitating machine-assisted research using Semantic Web technologies — something that will become even more critical once the mandate goes into effect and the percentage of open literature starts rising.
