Thanks!

The following projects have been extremely helpful to us:

The original epub.js which was a great proof of concept.

PDF.js has been extremely helpful in providing inspiration as well as ideas for how to handle certain challenges!

The IDPF! They make the EPUB standard!

Readium.js has been a useful sister project. It's wonderful to see how they've implemented things differently. It has given us perspective and new ideas, and we hope that we can be similarly useful to them.
