I was at my local Barnes and Noble today looking at the MySQL titles and found Sams’ choices amusing. They have 3 books which had damn near the same content, just slightly different titles: Sams Teach Yourself MySQL in 24 Hours, Sams Teach Yourself MySQL in 21 Days, and Sams Teach Yourself: SQL: In 10 Minutes.
How do they sell an author on these subjects? I can’t imagine what they say, “Hey guy, we’ve got a learn in 21 Days, but we think our readers would rather learn in 24 Hours. You think you could write something like that?”
Another funny observation on the topic. The 21 Days line was like $39, the 24 Hours line was $24, and the 10 Minutes line was $14. What is the logic there?
