I was looking for a book whose call number begins with P, but when I went to the stacks to get it, I couldn't find it.
Some books with "P" call numbers are located in the "Eisenhower Stacks" section of D-level--that's the section with white shelf labels. Other books with "P" call numbers are located in the "Eisenhower D-Level Blue Labels," on shelves with (you guessed it) blue labels. We are working on bringing these two collections together. In the meantime, be sure to note the precise location description for the book you want.
