This is a book that can contain and then produce any number of books. Placing a book beside or on top of this book (touching) and saying the magic word ("exemplum illud") will copy the book into this tome. Whenever the character wants to reference that book they just need to hold the Tome and think of which book they wish to read and the pages have been transferred when they open the book. This will not hold magic spells or spell books (anything that would require special magical inks or components or a cost to scribe) but could contain reference information on magic. It takes 1 second for each page side to copy into the Tome.
