You can fill out the Suggest a Purchase Form and the Collection Development Librarian will evaluate it for purchase. We are sorry that we cannot follow up with you to let you know if we intend to buy your suggestion.
However, you can make certain that the library doesn't already own the title. For example, did you spell the title correctly (google is a great spell-checker or you can find the title in amazon.com and confirm the correct spelling), did you search by the author's name if you didn't find it by title?
Also, use LINK+ to find a title that the library doesn't own. If you find an available copy, you can borrow it for free.
