Lib4RI aka libraries of the four research institutes of the ETH-Domain announced some days ago that they have made a list of all Open Access journals included in Science Citation Index Expanded 2013 (SCIE). Nice work! Matching is done against the Directory of Open Access Journals (DOAJ).
I added this information to the altmetrics web application of our publications since 2007. OA items are now indicated by a golden stroke around the circle.
There are few items among the PLOS articles published in the print version of PLOS Computational Biology, PLOS Medicine and PLOS Biology, respectively. Unlike in the Lib4RI data, their ISSN differs from that of the E-ISSN. Here are the correct ones: 1553-734X, 1549-1277, 1544-9173. I noticed these small typos thanks to the visualization.
