Announcing the world's first open-source, standards-based annotation capability for EPUBs, the fastest growing publication format.
Today we are announcing a partnership to bring open, collaborative, cross-platform annotation to eBooks. Together with NYU Libraries, NYU Press, Evident Point, the Readium Foundation and the EPUBjs project, Hypothesis will be working to bring annotation to EPUB, the standard format for digital books. Digital books represent an enormous class of content which at present cannot be collaboratively annotated with others. Combined with the recent work that the W3C has done to standardize annotation, this represents an essential next step in bringing a high quality open annotation implementation to books everywhere.
