***The links to any books or manuscripts  will take you to the library catalog of the Arizona State University-Hayden Library. They can be accessed there, or books can be interlibrary loaned through your local library if the material is allowed to be checked out/circulate. You can check if the book is available at either Northern Arizona University's or the University of Arizona's Library by going to the top of the screen and clicking on the icons that say NAU or UofA. They will take you to that college's library catalog and state whether they have copies or not. Information is also linked to the Arizona and Southwest Index which is also part of the Arizona State University Hayden Library.***

***Items in the Arizona and Southwest Index are located either in the Arizona Collection, Labriola, Chicano Collection or the Arizona Historical Foundation, but cannot be checked out. Location can be identified by the first letter in the call number. Items in the Arizona Collection are denoted by the prefix C. For Example CB BIO Hart, Pearl  would be a biography in the Arizona Collection of Pearl Hart. Just remember C is for Collection, M is for Chicano Collection, LAB is for Labriola, F is for Foundation. The second letter denotes the type of medium. B is for Biography, E is for Ephemera, and P is for photograph.***
