Baker & Taylor (B&T) is one of the oldest print book distributors, but it only recently entered the ebook market with its own fully fledged digital media platform, Axis 360. Since its launch in June 2011, the platform has gained some traction, with 107 libraries having signed contracts as of March 5 (38 sites are live).
This article is very encouraging. I'm interested to see how it shakes out. I really would like my library to offer ebooks from someone other than Overdrive. I think the fact that Axis 360 doesn't yet offer epub is a real detriment so until they offer more common formats, I think they are going to have a struggle.
