“Ah, but a man’s reach should exceed his grasp, Or what’s a [library] for?” (with semi-sincere apology to Robert browning)
I have been “buying” anywhere between seven and 30-something books a week for years (larger numbers once ebooks became necessary when I ran out of space no matter how diligently I purged my personal library). I only read about seven books a week (down from the 20-something I used to read when I was a lad), but I do find I discard more ebooks after partial reading than I have ever discarded hardcopy. Writing and editing standards have slipped terribly.
Still, having all my hardcopy classic collection backed up in multiple formats, media, and locations (and adding to it) is a Good Thing, IMO. Sadly, my non-fiction Kindle is out of storage space, now.
