Hot on the heels of [my
announcement](http://opencitations.wordpress.com/2012/06/11/nature-to-open-its-reference-list-data/)
on Monday that [Nature Publishing
Group](http://www.nature.com/npg_/index_npg.html) has agreed to open its
articles' reference lists, I am delighted to announce that *[Science
Magazine](http://www.sciencemag.org/)*, the [American Association for
the Advancement of Science](http://www.aaas.org/)'s premier global
science weekly, together with the other AAAS journals *[Science
Signalling](http://stke.sciencemag.org/)* and *[Science Translational
Medicine](http://stm.sciencemag.org/)*, will also open their articles'
reference lists, and contribute the bibliographic citations contained
within these lists as open linked data to an expanded [Open Citations
Corpus](http://opencitations.net), where they will be freely available
for everyone to use in whatever manner they choose.

Preparations to expand the corpus in this manner, by integration with
the reference processing pipeline of the [CrossRef Cited-By Linking
service](http://www.crossref.org/citedby/index.html), will be undertaken
over the last six months of this year, and incorporation of the
references from the AAAS journals into the expanded Open Citations
Corpus is planned to commence in the first half of 2013.

Now that the world's two most presigeous scientific journals have
declared their hands, it is time for other subscription-access
publishers to step up and join them, for the reasons given in [my
earlier
post](http://opencitations.wordpress.com/2012/06/11/why-publishers-should-open-their-references/). 
I am presently in discussion with a small number of other major STM
publishers, and hope to be able to make further announcements in the
near future.  However, there are many other publishers with whom I have
not yet been able to make personal contact.  Those who would also like
to become 'early adopters' of the Open Citations publishing model should
contact me at \<<david.shotton@zoo.ox.ac.uk>\>.
