Tim Berners-Lee's note on Linked Data gives a succinct description of the Linked Data principles. The Semantic Web community also maintains a list of books on a W3C Wiki page. Some of those books are introductory in nature while others are conference proceedings or textbook that address more advanced topics. Details of recent and upcoming Semantic Web related talks, given by the W3C Staff, the staff of the W3C Offices, and members of the W3C Working Groups are available separately; the slides are usually publicly available. The W3C also maintains a collection of Semantic Web Case Studies and Use Cases that show how Semantic Web technologies, including Linked Data, are used in practice.
