I just added a new matrix to the
Formats page of the MobileRead Wiki. The cross reference grid shows eink ebook readers along the top and formats down the left side. The types are divided into "eBooks", "Music", "Graphics", and "Compressed" with the formats under each. In each cell of the matrix is either "Yes" or "No".
The order of the device listing and the first few rows were lifted from the
Eink Comparison Matrix page of the Wiki.
There may be errors, please correct if you find any. There may be missing formats as the firmware for each reader improves. Also since some of the reader's specifications referenced for this project were based on prerelease data, this may change.
The big hole in the matrix is the omission of older ebook readers such as the eBookwise. If someone with that reader could add the supported formats we would all be better for it.
