I often found it best to buy one edition prior to what the lecturer's said if I needed the book and could not get a good deal second hand (though our second hand bookshop was really good (most books half price - I think I only had to buy 2 new text books in 3 years).Anyway, back to the main point. Most text books seemed to publish an edition every two years and for my purposes as a student all that was different was the page numbers and the occasional extra chapter (normally on something irrelevant) several times I saved about ?10 doing this.
