I ordered a used copy of Brewchem 101 on Amazon. Got it dirt-cheap; shipping cost more than the book. May be a good text to have during the course. I think A'zon has several more. But, be careful: On the one-click order button, if you get carried away, and click twice, you get 2 books.
If a-mazon means 'without breast', and 'ma' means breast, why is there a breast in a-ma-zon?
