### CC-BY with the ACS Author Choice: CDK and Blue Obelisk papers liberated

Already a while ago, the American Chemical Society (ACS) decided to allow the Creative Commons Attribution license (version 4.0) to be used on their papers, via their Author Choice program. ACS members pay $1500, which is low for a traditional publisher. While I even rather seem them move to a gold Open Access journal, it is a very welcome option! For the ACS business model it means a guaranteed sell of some 40 copies of this paper (at about$35 dollar each), because it will not immediately affect the sale of the full journal (much). Some papers may sell more than that had the paper remained closed access, but many for papers that sounds like a smart move money wise. Of course, they also buy themselves some goodwill and green Open Access is just around the corner anyway.

Better, perhaps, is that you can also use this option to make a past paper Open Access under a CC-BY license! And that is exactly what Christoph Steinbeck did with five of his papers, including two on which I am co-author. And these are not the least papers either. The first is the first CDK paper from 2003 (doi:10.1021/ci025584y), which featured a screenshot of JChemPaint shown above. Note that in those days, the print journal was still the target, so the screenshot is in gray scale :) BTW, given that this paper is cited 329 times (according to ImpactStory), maybe the ACS could have sold more than 40 copies. But for me, it means that finally people can read this paper about Open Science in chemistry, even after so many years. BTW, there is little chance the second CDK paper will be freed in a similar way.

The second paper that was liberated this way, is the first Blue Obelisk paper (doi:10.1021/ci050400b), which was cited 276 times (see ImpactStory):

This screenshot nicely shows how readers can see the CC-BY license for this paper. Note that it also lists that the copyright is with the ACS, which is correct, because in those days you commonly gave away your copyright to the publisher (I have stopped doing this, bar some unfortunate recent exceptions).

So, head over to your email client and email support@services.acs.org and let them know you also want your JCICS/JCIM paper available under a CC-BY license! No excuse anymore to make your seminal work in cheminformatics not available as gold Open Access!

Of course, submitting your new work to the Journal of Cheminformatics is cheaper and has the advantage that all papers are Open Access!
