Digital Object Identifier or DOI is a persistent identifier or handle used to uniquely identify objects. DOIs are in wide use mainly to identify academic, professional, and government information, such as journal articles, research reports and data sets, and official publications though they also have been used to identify other types of information resources, such as commercial videos.
A DOI aims to be "resolvable", usually to some form of access to the information object to which the DOI refers. This is achieved by binding the DOI to metadata about the object, such as a URL, indicating where the object can be found. The DOI for a document remains fixed over the lifetime of the document, whereas its location and other metadata may change. Referring to an online document by its DOI is supposed to provide a more stable link than simply using its URL.
DOI names can identify creative works (such as texts, images, audio or video items, and software) in both electronic and physical forms, performances, and abstract works such as licenses, parties to a transaction, etc. The names can refer to objects at varying levels of detail: thus DOI names can identify a journal, an individual issue of a journal, an individual article in the journal, or a single table in that article. The choice of level of detail is left to the assigner, but in the DOI system it must be declared as part of the metadata that is associated with a DOI name.
How can I get a DOI for my . . . article, chapter, report, dataset, video, etc.?
DOIs for journal articles, or other types of publications, are usually issued by the publisher.
The Drexel University Libraries subscribes to DataCite, one of the Registration Agencies that manage DOI creation and registration services, and can assist with providing DOIs for datasets and other non-published "objects". The Libraries' requirements for providing a DOI is that:
To request a DOI for your research work:
Please contact the Libraries via email@example.com if you need assistance with this service.
Many search engines and databases can be used to find a journal article associated with a DOI. To find Drexel-subscribed sources for full-text, try:
Note that your search results may include articles that CITE the article you're seeking, because the DOI is included in the references.
