Fascinating information for all bibliophiles like myself: Google has determined that 129,864,880 different books have been published in the entire history of publishing. Other interesting facts:
- Books have been published in about 480 languages (including 3 in the Klingon language).
- 20% of all books are in the public domain.
- 10-15% of all books are currently in print.
- The rest are out-of-print but still under copyright.
I figure I have read perhaps 2,000 books in my lifetime, which is approximately 0.001540062% of all books ever published. I sure have some work to do!
