Re:What's the deal? (Score 1)

After getting laid off from a dot bomb in 2002, I taught math at the local community colleges for over three years. Although I taught many of the classes multiple times we NEVER used the same text book for more than a year. The usual trick was to go with a new edition, the sections and problems were subtly rearranged so it made it difficult to use an older edition. The students got shafted two ways, in the Fall it was hard to find used books and in the Spring the bookstore wouldn't buy them back because they wouldn't be using them again.
