Comment on Elsevier Editors' Update by Henk Moed: "Does Open Access publishing increase citation rates? Studies conducted in this area have not yet adequately controlled for various kinds of sampling bias." http://editorsupdate.elsevier.com/2012/03/the-effect-of-open-access-upon-citation-impact/
No study based on samples and statistical significance-testing has the force of an unassailable mathematical proof. But how many studies showing that OA articles are downloaded and cited more have to be published before the ad hoc critiques (many funded and promoted by an industry that has something of an interest in the outcome!) and the hopeful special pleading tire of the chase? There are a lot more studies to try to explain away here: http://opcit.eprints.org/oacitation-biblio.html Most of them just keep finding the same thing... (By the way, on another stubborn truth that keeps coming back despite untiring efforts to say it isn't so: Not only is OA research downloaded and cited more -- as common sense would expect, as a result of making it accessible free for all, rather than just for those whose institutions can afford a subscription -- but requiring (mandating) OA self-archiving increases OA self-archiving. Where on earth did Henk get the idea that some institutions' self-archiving "did not increase when their OA regime was transformed from non-mandatory into mandatory"? Or is Henk just referring to the "mandates" that state that "you are required to self-archive only if and when your publisher says you may self-archive, and not if they say you may only self-archive if you are not required to"...? Incredulous? See here -- http://openaccess.eprints.org/index.php?/archives/822-.html -- and weep for the credulous [or chuckle for the sensible]...)
