Puzzle Box, Volume 3 is a nice collection of challenging puzzles, including logic problems, 3D puzzles, Tetromino, numbers puzzles, Mazes, Put-Togethers, and more. The difficulty level ranges from medium to 'Guru' level. The puzzles are packed tightly together, sometimes 5 or more to a page, and all of the solutions are provided in the back of the book.
This would not generally be added to a public library's collection, but I do enjoy these types of puzzles myself, and found it to be a pleasant mix of puzzle type and difficulty.
Overall, a nice selection of difficult puzzles for the puzzle enthusiast.
