CrossRef, the official DOI registration agency for scholarly and professional publications, harnesses collaboration among publishers to provide the scholarly community with easier access to online research content. CrossRef was established in 2000 as an independent, non-profit membership association, with a mandate to make cross-publisher linking throughout online scholarly literature efficient and reliable using the DOI system. "DOI" stands for Digital Object Identifier and is an open standard. A DOI is an alphanumeric name that identifies digital content, such as a book or journal article. The DOI is paired with the object's electronic address, or URL, in an updateable central directory, and is published in place of the URL in order to avoid broken links while allowing the content to move as needed. DOIs are distributed by publishers and by CrossRef, and there is no end-user charge associated with their use. The DOI can be assigned at any level of granularity and incorporated into many different systems and databases. What do DOIs link to? CrossRef DOIs link to publisher response pages, which include the full bibliographic citation and abstract, as well as full-text access (for authenticated users or at no charge, as determined by the publisher). The publisher response page often includes other linking options, such as pay-per-view access, journal table of contents and homepage, and associated resources. Libraries with local link servers can have DOIs automatically redirected to appropriate resources. The key benefits of the CrossRef DOI for libraries are: - Truly persistent links - Increases usage of acquired resources - Expanded access to content not owned - Enhanced localized linking - DOI and metadata retrieval privileges at no cost to most libraries Please take a tour of the CrossRef system or visit our gallery of linked publisher websites. Our "fast facts for libraries" area provides answers to many common questions about CrossRef. There is no charge for most libraries to get a CrossRef account to retrieve DOIs or metadata. Through CrossRef, libraries can create links to CrossRef member publishers without signing bi-lateral linking agreements with each publisher and without having to track publishers' individual linking schemes. The CrossRef system also supports DOI re-direction for the purposes of localized linking within library holdings. More information about how the DOI integrates with local link servers is available at our "OpenURL and CrossRef" page. In most cases, information providers (publisher, database producers, etc.) will use CrossRef to add DOIs to their content and databases, so libraries will not need to use CrossRef for DOI retrieval alone. If libraries host local content, the content providers should add DOIs before delivering the content. Users browsing online content will see DOI links and click on them -- there is no charge for clicking and following DOIs links. High-volume query fees (new as of January 2005): Libraries who submit over 1 million queries within a given year will be assessed a fee of $3,000 at year-end; libraries who submit over 10 million queries within a given year will be assessed a $10,000 fee. To become a Library Affiliate, here are the steps you need to take:
You and your patrons can always look up DOIs at no charge at our free query interface. If you encounter a DOI, you can resolve (link) it automatically at our DOI resolver.
Don't publish online in the dark...just DOI it! Amy Brand, Director of Business and Product Development 781-295-0072, Fax: 781-295-0077, abrand@crossref.org
