Special Collections is the department in the University of Houston Libraries which stores and provides secure access to rare and unique materials, including archives, manuscripts, rare books, or other original materials. Most of these materials are considered primary sources, although sometimes that categorization depends on the research question being asked.

Special Collections is located on the 2nd floor of the Blue Wing, and has its own hours that are different than the rest of the library's hours. The staff in Special Collections are available to help you find primary source materials.
