I am 100% sold on the advantages of the electronic format (specifically Logos) over printed books. I've invested a lot in my Logos library and have ceased adding to my printed library. In some upcoming seminary courses some of the required textbooks are available in Logos as well as in print, and I do have a bit of uneasiness about going electronic here. When I have to know and be tested on a 400 page book cover to cover, I'm just wondering if mentally I can retain the material as well as with a book where each line always falls on the left or right side, at the same spot on the page, every time I open it. I'd love to hear any thoughts, suggestions, and experiences from others.
