1. All library stacks have numbers assigned. They are numbered sequentially with #1 being the first "range" of stacks on any given floor. A range numbered as #1 will have the lowest, or first, call number that is located on that floor.
2. First floor and the basement are exceptions to this rule. This is a result of different call number systems being used on these two floors. If you need additional help locating materials on first floor or in the basement, please ask for assistance at either the Reference or Circulation desks.
3. Purple signs have been placed at each end of every range of stacks containing items with Library of Congress call numbers. Blue signs have been used for stacks containing Superintendent of Documents call numbers.
4. Both kinds of signs have a number at the top that indicates the "range number." If you navigate the stacks starting with range #1, and follow them in range number order, you will also move through the call number order.
