Deep Blue Repositories provide safe and permanent access to research materials, including documents and data. Deep Blue Documents offer repositories for articles, chapters, dissertations, conference presentations, media, and other work produced by the U-M community. The majority of documents are searchable and viewable by everyone, though authors can apply some access restrictions. Deep Blue Data provides access to digital research data that were developed or used in support of research activities at U-M. Repository data are available for anyone to download without restriction. Deep Blue encourages users to share and preserve their work in a repository. The repositories come with a stable URL, usage statistics, as well indexing in search engine abilities like Google Scholar.
