Ala. Code § 11-25-7
Upon the establishment of a county law library under the provisions of this chapter each county shall have and maintain a separate fund known as the County Law Library Fund and may have a separate law library fund for each law library in the county. The county law library funds shall consist of funds appropriated by the state, county, or municipal governments, funds collected under the provisions of law, proceeds from the sale of copies, books, and other materials, or received from donations, gifts, grants, and funds other than those appropriated, and shall be audited as county funds are audited. Said fund may be used to match grants for library purposes. Library funds may be used to pay library personnel. All purchases by or on behalf of such library shall be exempt from all State of Alabama, county, or municipal sales, use, or other similar taxes.
