EPUBTest.org is home to both the BISG EPUB 3 Support Grid, a summary of e-book app, device, and reading system performance evaluations for features supported by the IDPF EPUB 3.0 e-book file format, and the EPUB Testsuite, a freely available collection of material created specifically for this purpose. These files were used to generate the results in the BISG EPUB 3 Support Grid.
