I have almost all of our manuals in digital form. For most of them, I found PDF copies on line that I downloaded. As a matter of fact I just downloaded one of the last ones today. For a few, I did not find them on line, so I scanned each page, then put them into a word document and printed it out to a PDF file.
I do still have most of the paper copies, but I do like having the digital copies. I put a set on my Nook e-reader, one set on my windows tablet and one set on a hard drive & DVD data disk, just in case.
