In the Getty Virtual Library, visitors can read and download over 250 publications made freely available from the Getty Museum, Getty Conservation Institute, and Getty Research Institute. Museum publications include exhibition catalogs and full issues of the Museum Journal. For example, view Julia Margaret Cameron: Complete Photos, a 259-page catalogue raisonne of Cameron's work, published in 2002. Librarians, archivists, and museum professionals will find helpful resources from the Conservation and Research Institutes on topics ranging from metadata and vocabularies to the digitization of cultural heritage materials. Some titles included are: Introduction to Metadata; Introduction to Controlled Vocabularies: Terminologies for Art, Architecture, and Other Cultural Works, 2010, by Patricia Harpring, foreword by Murtha Baca; and a 2003 update of Howard Besser's Introduction to Imaging originally published in 1995, and widely regarded as a standard textbook for the creation of digital collections.
