On my way to pretty much fully digital as well. Just got back from my 90 degree storage, spending 3 hours getting about 10 boxes of books ready to give to one of our Pastors, to give to someone looking into ministry he knows. Was going to give him all of the books I have, then decided to keep my Dictionaries, Lexicons, and Encyclopedias, etc. Reference works. Just in case something ever does happen to Logos, I can still potentially dig into the text. There is so much theology online, that even if Logos were to go down, I couldnt read it in a life time. But some of those Lexicons are expensive, and harder to come by. The TDOT alone cost me $500 used, and that was almost 10 years ago.
