Yesterday I got a small pile of books. I already had them, but wanted to prevent them from getting lost. I noticed that one of the books looks different from the version that I already had:
The one on the right is the new one. Initially I thought the hard cover had been taken off, but the back has the title as well. Besides, the titles are different. The brown book has a soft cover, hardly thicker than the sheets, but it appears to be a another edition in which a strange typo of the original cover was corrected. The font is slightly different.
This book isn’t too easy to find, but I had never ran into the ‘second edition’ before at all.
