Tagging

Tagging essentially enables users to create subject headings for the object at hand. It allows users to add and change not only content (data) but describing content (metadata). in flickr, users tag pictures. In LibraryThing , they tag books and thereby participate in the cataloging process. tagging simple makes lateral searching easier. "They often-cited example of the U.S Library of Congress subject heading 'Cookery', which no English speaker would use when referring to 'cookbooks', illustrates the problem of standardized classification. Tagging would turn the useless 'cookery' to the useful 'cookbooks' instantaneously and lateral searching would be greatly facilitated" (Maness, J.M., 2006).

This could make user follow both standardized and user-tagged subject that could suitable to the users and this could help libraries to provided information that with qualities that follows the standard and with scientific subject and could be quality research done and cited by the users. This could see the import role of libraries in information literacy learning environment as in the same time could educate users and provide standard information for users bebefits.
