I realize that Bookpedia can import epub format, but what about other formats, such as .lit and .html? Right now, it ignores them. And, as someone posted in a thread, the ability to track multiple formats for the same title would help, too.
Do please email us some samples .lit format files so that we can look at integrating that more closely. In the meantime you should be able to link any type of file into the links section of Bookpedia an use an external editor to view and work with these format.
