I have added the Spivak and Jacobs books to my wishlist to keep track of for future reference. smile

This whole subject is why I still have my old textbooks, and why I buy old textbooks at yard sales and library sales -- I figure they're only getting worse, so we can always go back and refer to the old ones if the new ones are incomprehensible. And, indeed, we do refer to the Algebra and Geometry ones when DS's e-school materials leave us scratching our heads.
