From: Anali Perry <[log in to unmask]> Date: Tue, 28 Mar 2017 01:03:34 +0000 Hi Ann, I'm sorry I wasn't more clear in my earlier response. Unpaywall only searches institutional repositories and publisher sites, so it's about as legal as one can get - assuming all articles on publisher's sites are legal, as well as whatever posted on a repository being vetted by repository management. Regarding which version, if it is on a publisher's site, it will be the final published version. If it is on a repository, the default assumption is likely author's final manuscript, but most repositories have some indicator about which version was archived - there are some cases where final published version is allowed, for example, and the repository description would probably reflect that.

"OA version" isn't exactly an answer, or at least not what I was wondering. Assuming that what is pointed to is definitely legal, what I meant is, how does one know if this is a final final published version, an e-print version, an author's manuscript version, etc. Cheers, Ann Okerson On Wed, Mar 22, 2017 at 4:52 AM, LIBLICENSE <[log in to unmask]> wrote: > From: Anali Perry <[log in to unmask]> > Date: Tue, 21 Mar 2017 15:41:08 +0000 > Subject: RE: ImpactStory releases new Chrome Extension: Unpaywall Hi > Brian, > > Google Scholar does not reliably index all institutional repositories > (there have been a few studies documenting this - there are issues on > both the repository & Google sides).
