Picture/Coffee table books
Sometimes, you buy books for their pictures, not their
content -- and I found both of these books on the
remaindered pile at Borders, they were a cheap addition
to the growing pile of books next to my couch.
When the Pyramids Were Built
Egypt: World of the Pharaohs
There are dozens more, of course. And, if you aren't
as dedicated a collector as I am, the library has
shelves full of the things to browse through.
You might, of course, be more interested in the actual
history and reference books.
