I think it’s a great idea for authors to share “free access” — often limited to a certain number of downloads — with blog readers. As a glance at the map in the righthand sidebar reveals, people access this blog from all over the world, and many of them do not have institutional access to the journals in which we publish.
To keep things manageable, though, I suggest the following process. If the article for which you would like to provide free access is published in one of the journals whose Table of Contents I regularly post (see here), then please add a comment to the relevant ToC post, giving the information about downloading a free copy. If I have missed posting the ToC in question, then please remind me!
If your article is not in one of those journals, then when you tell me about the article (for the weekly digest), please also tell me about the free access information; or else, add it in a comment to the relevant weekly digest.
