I mainly use Calibre to manage my epubs/mobi/pdf's. It is quite nice to be able to "create" a library of all my ebooks. I also use Calibre to manage my Kobo e-Reader. I am even able to "read" an ebook directly from Calibre.
I was wondering: wouldn't it be great if Logos could, almost like Calibre, contain an epub/mobi/pdf reader and the ability to incorporate these resources into the Library (almost like PBB's). If Logos could incorporate epubs/mobis into myLogos Library and allow me to do simple searches in these ebooks, then it would be a dream come true. I have quite a selection of theological/Biblical ebooks in other formats, and it would be excellent if I could do all my research from a single program. Of course, there will be great limitations, but I do not see any problems with copyright issues since there are numerous epub/mobi readers on the market.
Just an idea.
