Is the 15th edition of General Zoology Laboratory Guide different from its older version?
Is the 15th edition of General Zoology Laboratory Guide , by Charles Lytle, John Meyer, different from its older version ( the 10th ? the 13th ?)
If it is familiar I can buy an older version online for much cheaper. Please help if you know !!! Thanks so much!!!
A lot of books has no actual updates but the edition numbers in order to receive more profit from buyers. That's why I'm asking
