The American Chemical Society announced recently that it would begin making select articles from its archives freely available on its website:
One new peer-reviewed research article from any ACS journal will be selected to be freely available every day; the selection of these articles is based on recommendations by the scientific editors of ACS journals from around the world. As a service to the ACS global community of researchers, the articles listed below will remain open for all to access and read.
The program is called Editor's Choice, and the selected articles will be promoted and available from the ACS Publications Home Page, as well as via Facebook and other social media.
ACS Editors’ Choice Home Page: http://pubs.acs.org/editorschoice/
