With the price of books these days, unless I'm sure I'll want to keep the book after reading it, I usually borrow it from a local library. Plus, having read so many sci fi books over the years, I'm finding I no longer enjoy them when they repeat a timeworn theme or plot device. I'm sure that twenty years ago I would have been fine with the same book. So most sci fi books I borrow from the library now. Plus, most non-fiction is in expensive hardcover form so some of those come from the library too.
Anyone else out there borrow from libraries? If so, why?
