The Library is Cheaper Than the Book Store
In college in the mid-Aughts, I probably saved a few thousand by checking older editions and books out from the library instead of buying them. Couldn’t really do it with science books, but I was a history major and almost an English minor (dropped it the last semester cause I didn’t want another paper to write, and I figured an English minor would be useless anyway).
Other than differences in page numbers, the previous editions were pretty much exactly the same (who would’ve thought little to no additional information would come out on the Gilded Age or Victorian England between the 3 years between the 2003 6th editions of those textbooks and the 2006 7th editions).
At that time, the campus library would let you continuously renew the book if no one had requested it in the meantime, so I could hang on to most of them throughout the semester.
