Whittaker (special collections, The Ohio State U. Libraries, Columbus) and Thomas (rare books and special collections, Northern Illinois U., DeKalb) present collection and archives professionals with an examination of the use of Web 2.0 applications and related technologies in the creation, promotion, and management of special collections resources, particularly as a strategy for reaching new audiences. The text incorporates findings from 300-plus responses to a survey gauging the knowledge of and interest in Web 2.0 applications among cultural heritage professionals. The authors discuss the use of specific applications--wikis, blogs, social networking, photo-sharing sites--as a gateway to special collections material, and examine how these technologies may affect digitization projects, preservation of born-digital materials, and funding agency response.
