This week’s Website of the Week is Mental Floss. This site is a very interesting collection of curious facts and amazing information similar in some ways to Brainpickings, the “digest of interestingness”. I first stumbled upon this site when reading an article about 62 of the World’s Most Beautiful Libraries. If you are a lover of books and especially libraries you must check this list out. Some of the most amazing, beautiful and interesting spaces to hold books are listed in no particular order.
