Fiction & Biographies
Fiction books are arranged alphabetically by the author’s last name. The label shows the first seven letters of the author’s last name. Adult fiction is on the 28th Street side of the 2nd floor, next to the windows. Juvenile fiction is on the 1st floor behind the Children's Services desk. Young Adult (Teen) fiction is in the Teen Pit on the west side of the 2nd floor behind the glass wall.
Biographies are shelved by the last name of the person the book is about. The call number has a B for biography above the person’s last name and the name of the author of the book. Adult biographies are on the 28th Street side of the 2nd floor, next to the windows, back towards the northeast corner. Juvenile biographies are on the 1st floor north wall. Young Adult (Teen) bios are in the Teen Pit on the west side of the 2nd floor behind the glass wall.

Nonfiction
The Dewey Decimal System numbers nonfiction materials by subject. The number on the book’s spine is that of the subject area above the first letters of the author’s last name. The numbers are the same for all items on the subject, whether they are adult, youth services, oversize, audiovisual, Reference or Montana Room materials.

Oversize Nonfiction
Oversize books are those that are too big to fit on regular shelves. They are shelved on the north wall of the 2nd floor, behind the other book shelves. Oversize books check out for the regular 28 day loan period. Call numbers for Oversize books are identical to those on the regular shelves. The label will have the letter "O" or the word “OVERSIZE” above the number and author’s name.

Reference & Montana Room
These items may be used in the Library building, but may not be checked out. This may be because they are rare, very expensive, in constant demand, or all of the above. The Montana Room is open during normal library hours & is located on the 2nd floor on the west side adjacent to the elevator. Reference books will have an R above the call number on the spine ["YR" in the Teen Pit and JR in Youth Services]. Montana Room materials will have either an M or MONTANA above the call number on the label. The adult reference collection is on the 2nd floor between Adult Fiction and adult non-fiction. For more information, ask one of the Library’s staff members for assistance.
