- The houses in Higgs Village have a total of 171 books.
- 158 books in Nelson, in the house next to the barracks. However, these books are all considered owned and will cause the Courier to lose Karma.
- The abandoned Brotherhood of Steel bunker has plenty of books as well, but requires the installation of the Dead Money add-on.
- The X-8 research center has upwards of 181 books scattered across its interior (The largest amount being found in the library in the testing area).
- There are plenty of books in metal boxes and next to book shelves throughout The Divide in Lonesome Road.
- Another great place to find books is the Lucky 38 penthouse.
- 75 books in Doc Mitchell's house that do not need to be stolen.
- There are a good number of books on the second and third floors of the Bison Steve Hotel.
- The REPCONN test site has over 250 books that do not need to be stolen.
- The Courier needs 25 blank books to make one skill book.
- The exchange of books is 1 to 1, no matter the size of the old book. A total of 325 books is enough to produce all of the recipes.
- As with many of The Sink's personality units, the Book Chute's function makes a previously worthless group of items hold much greater value, albeit to a more limited degree. The first 325 can be used for a greater purpose, though converting books after that point merely makes storing a still-worthless item slightly easier.
