BASIC engineering and scientific programs for the IBM PC Book

This was a good book for a non-fiction historical book. Sometimes those books are tedious for me, but this was well-written and easy to ready. It took me awhile to finish, but it was not the book's fault. The book is about William Henry Jackson, one of the first well-known photographers in America. He traveled west and photographed the uncivilized west, and his photos were used to convince Congress to begin setting aside tracts of land for national parks.
