I'm slowly replacing my pbooks but the problem is that most require scanning by me and that takes a great deal of time. Fiction I have no problem with replacing, most of it is one time use. But I have shelves full of needlecraft books and magazines (knitting, crocheting, cross stitch, needlepoint, quilting, sewing, etc.) that I would like to greatly reduce and that's what I'm concentrating on with my scanning efforts.
I have dust and mold allergies so old books can make me literally sick.
