The C Collection serves as the library’s main collection of old, rare, or unique books. Included is a collection of Bibles that spans over 700 different languages and/or versions — including the Waynai Bible (the World’s Largest). There are also many texts from various religious groups, as well as literary sets and encyclopedias too rare and valuable to shelve in the main stacks.
There is also a collection of older and newer books covering the history of Texas. Important in this collection are several histories from surrounding counties and a mostly-complete set of early Abilene city directories.
