The code necessary to load and use various datasets is provided with this repository. Below is a list of the datasets currently supported.
The Book-Crossing dataset is a collection of user ratings of books. It comes with both explicit ratings (1-10 stars) and implicit ratings (user interacted with the book). The data was compiled by Cai-Nicolas Ziegler of IIF and can be found here.
More information about the data is available in Ziegler et al.:

The last.fm HetRec 2011 dataset includes the play counts of a set of artists by a set of users. Also included are tags applied by the users to the artists and a social network graph of the users friends. The dataset comes from last.fm and was compiled by Ignacio Fernández-Tobías, Iván Cantador, and Alejandro Bellogín and is available here.
