The Wall has a powerful search engine that will go all the way back to 2002. Use "quotation marks" around multiple-word searches. RIGHT-CLICK on the results and choose Open Link In New Window so you'll be able to get back to your results. Happy searching!
In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I'd like to suggest another source of old books. Try "addall.com". It searches lots of other used book search engines; sort of one stop shopping. You'll find books by Frederick Dye and John Tyndall; great teachers of plumbing and physics. Their work is nearly as good as that of Dan H!
