EPUB Canonical Fragment Identifiers (epubcfi) allow for a powerful and standardized way to reference locations in an ePub. They are core to the rendering and navigation features in Epub.js and have been significant updated in v0.3.

Epub.js, a JavaScript library for rendering ebooks (using the ePub format) in the browser and on mobile devices, is used by a growing community in projects ranging from library catalogues to self published novels. Recently there has been a return to the our roots with several projects adopting it for academic research. The first request from these projects is always: how can we allow annotation in our reader?
