This includes nursing homes and jails but does not include bookmobile stops. Hours open per week are the hours open of the main library for winter and summer. Total annual public service hours are the combined hours for the main library, bookmobiles, and all branches. All facility open hours were totaled regardless of whether or not they were open at the same time. In this section, libraries have reported the number of physical units and titles owned, both cataloged and uncataloged, at the end of the year.
Physical units are volumes, items or pieces.
Items which are packaged together as a unit, e.g., two compact discs, two films, or two video cassettes, and are generally checked out as a unit, should be reported as one physical unit. A title is a publication which forms a separate bibliographic whole, whether issued in one or several volumes, reels, discs, disks, slides, or parts. The term applies equally to printed materials, such as books and periodicals, as well as to audiovisual materials and microforms. Duplicate copies are reported as one title. The World Book Encyclopedia would be 1 title and 26 physical units.
