Dermatology Online Journal is a refereed publication designed to meet reference and education needs of the international dermatologic community. DOJ is a well-established, first tier scholarly journal indexed in MedLine that has been published since 1995 by UC Davis. It provides opportunities for experimenting with access to rich supplementary materials, such as the images and data sets associated with clinical medicine. With the January 2001 release of this Web site, eScholarship support of DOJ and the dermatology community is being extended to include a prototype Dermatology Digital Repository. ePrint Repositories are part of the essential technology infrastructure for the experimentation and innovation eScholarship exists to support. The articles and papers deposited herein will be digitally archived and persistently available on University of California servers.
