The American Society for Biochemistry and Molecular Biology (ASBMB) - publishers of the Journal of Biological Chemistry (JBC), Molecular and Cellular Proteomics (MCP) and the Journal of Lipid Research (JLR) have announced that they will make all their content freely available through the PMC and UKPMC repositories, with a 12-month embargo. [Previously ASBMB were only depositing NIH and "Author Choice" papers to PMC/UKPMC.]
Researchers funded by any of UKPMC Funders should continue to make use of the ASBMB "Author Choice" option. On selecting this option, papers are made available at PMC/UKPMC at the time of publication (no embargo), and are licenced using the Creative Commons, Attribution, Non-Commercial licence (CC-BY-NC). This licence allows uses to copy, distribute and transmit and adapt the work, subject to attribution and that it is undertaken for non-commercial purposes.
Author Choice papers are also included in the PMC OAI set, which allows users to download and harvest the content in XML format (e.g. see a recent JBC article in html and XML).
