FYI. Anyone, interested in collecting physical, real books, should consider the Goodwill, Salvation Army, Thrift Stores, ETC... Most of their books range from $1 - $3, (price of a Sunday newspaper,) I have picked up high quality, glossy paper, autographed books, by Olympic Champions & Professional Athletes', books. I love old High School & College yearbooks. Many are Leatherbound, with 100-year-old student comments. One book had a $279, MSRP, printed on the dust cover. Most of these books were probably, treasured by original the owners, only to be discarded or donated, by Parent's Children. Book collecting can be a rewarding and inexpensive hobby. And preserving the past, remembering how our Parents and Ancestors lived, and more...
