I was wondering if it was possible/legal to simplify and add interest to a series of nonfiction books written in the 1870s. The info in them is great and its by a prominent author, but the books are no longer in print and very dense to read. I was thinking about rewriting them in modern language and adding a little spice to add interest, while keeping the integrity of the historical information and authors views. I would of course make it clear that it is a "re-write". I'm interested to hear thoughts on this possibility. Thanks!
