This site (tagline: “Catalog Your Books Online”) is a utilitarian alternative to Goodreads. There are fewer frills and the look isn’t as slick as Goodreads, but there’s also no advertising staring you in the face. The basics are all there: reviews, collections, groups, and discussions.
Billed as “part kids’ social network, part parent’s guide, part teacher’s tool,’ BiblioNasium is geared toward the education market, and it’s very kid friendly. Teachers can join, generate class accounts, and create a reading network with their students, who can respond to books and post their own reviews.
