I post things to Boots that I find interesting at the time.
My catalog comes from listing the free books I want to read or have read, normally classic books. I started to read free (classic) books a few years before my first eReader, and let me tell you that electronic books are the way to go. Today I just use an 8 inch Windows tablet to do my reading. I decided this was the smartest thing for me because 1. I no longer just wanted the eReader maker's selection, and 2. I can organize a library on my computer using custom folder and file names.
