The Librarian's Almanaq

Here is an excerpt from The Librarian's Almanaq's official website:

Now, in your hands, you hold The Librarian’s Almanaq, an opus that is the culmination of literally centuries of tremendous work by a dedicated team of researchers. Here, you’ll get the advice you need to be successful in the world and learn the sine qua non of puzzledom. Never before has a wealth of information like this been gathered in one place, let alone a single volume. Your hunger for sacred knowledge can finally be sated! Examine the Almanaq carefully and make sure to read the Instructions, and you will be on the path to enlightenment.

The Librarian’s Almanaq is an all-in-one puzzlehunt, an interconnected suite of ten unique and fun puzzles, culminating in a satisfying conclusion, and all put together in a form you’ve never seen before.

Solving time is 8-40 hours for 1 person; proportionally less for groups. You will need a large table or floor space to work on, plus a pen or pencil, scissors, and transparent tape to solve the puzzles. A highlighter, felt-tip marker, and a live duck would be handy.
