Tarleton State University Libraries Unit 5 LOCATING ITEMS USING CATALOG INFO   To locate an item using information obtained from the catalog, you need to know at least three things: •  which library houses the item, •  the item's call number, and •  which collection to look in. In addition, you need one more piece of information before trying to retrieve an item: where to find the different library collections. Collections in the libraries are housed in different areas based on their primary purpose and/or format. For example, reference books are shelved together to provide easier access to the materials, periodicals are housed together due to their format, and microform cabinets are located close to the periodicals because most of the materials on microfiche and microfilm are periodicals. To learn the location of specific library collections, use the online floor plans for Dick Smith Library and for Tarleton Library – Central Texas.   Understanding an Item's Record LC Classification & Call Numbers   Library Orientation Site Index Updated 8/2004
