What to do with excess unbound calculator books and manuals

[Duane Hess]

Hi:

I would be interested in the specific items:
Engineering Statistics with a Programmable Calculator, 1982 (William Volk)
Scientific Analysis on the Pocket Calculator, Edition 2, 1977 (Jon Smith)
Calculator Programs for Chemical Engineers Vol. 2, 1984 (David J. Deutsch)
Mathematical Astronomy with a Pocket Calculator, 1978 (Aubrey Jones)
How to Program Your Programmable Calculator, 1979 (Stephen L. Snover, Mark A. Spikell)

I live in Nebraska, sounds like media mail is a good choice; although untrackable. If binding is somewhere $3-$5 per item, that works for me.

Please let me know if they are still available.

thanks
