I finally found an eBook reader that does everything I want it to on my netbook! FBReader is a completely free eBook reader that will handle all the formats that I need it to. It runs very nicely under the cut-down version of Linux that’s installed on my netbook. It allows the “paper” to be changed to any colour that suits you (I like sepia!) and even permits screen rotation. The control keys are fully configurable, so that you can, for example, set up keys to move through the book in pages or scroll a line at a time. The only problem I have is passing a “command line argument” from Jutoh, so I can’t (yet) launch the current book automatically.
The FBReader web site includes a very useful list of eBook sources, if you want to increase the size of your library!
FBReader is available for Android devices, Windows, Linux and a host of other systems, though some are older versions of the software.
