: Exemplar - It's a keeper for reading again. Rush out and buy copies for friends.
: Good - read it again and loan it out or give to friends when shelves full.
: Decent - share with readerholics but don't promote, and sell or swap when shelves full.
: Disappointing - fine if nothing better to read but sell or swap ASAP.
: Terrible - just sell or swap and wipe from memory
