1DollarScan

Scans books for one dollar and sends you the PDF. service offered in USA. Offshoot of popular Japan based service BookScan.

Caveat, they will cut the spine of the book before scanning. So, I will not be sending my 1922 edition of Wren and Martin.

This is a good way to convert old books that we no longer want to keep around but may need the material for reference.
