A digital object identifier (DOI) is a type of persistent identifier used to uniquely identify objects. The DOI system is particularly used for electronic documents such as journal articles. The DOI system began in 2000 and is managed by the International DOI Foundation. 


DOI means "digital identifier of an object" rather than "identifier of a digital object". 


Metadata about the object is stored in association with the DOI name. It may include a location, such as a URL , 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 provides more stable linking than simply referring to it by its URL, because if its URL changes, the publisher only needs to update the metadata for the DOI to link to the new URL. 


A DOI name differs from standard identifier registries such as the Journal Research Paper. The purpose of an identifier registry is to manage a given collection of identifiers, whereas the primary purpose of the DOI system is to make a collection of identifiers actionable and interoperable. 


Organizations that meet the contractual obligations of the DOI system and are willing to pay to become a member of the system can assign DOIs. The DOI system is implemented through a federation of registration agencies coordinated by the International DOI Foundation, which developed and controls the system. The DOI system has been developed and implemented in a range of publishing applications since 2000; by late April 2011 more than 50 million DOI names had been assigned by some 4,000 organizations. By April 2013 this number had grown to 85 million DOI names assigned through 9,500 organizations. The DOI system uses, but is not formally part of, the Handle System.


Anyone wishing to get this service has to sign an agreement with a DOI registration agency and pay an annual fee, which is at least 275 dollars plus 1 dollar per DOI, we bear this cost and our others enjoy better services. Crossref is our content registration agency and we are working with EDUINDEX

DOI (Digital Object Identifier) is a unique identifier that identifies digital objects. The object, itself, may change physical locations, but the DOI assigned to that object will never change. Journal publishers are assigning DOIs to electronic copies of individual articles in journals they publish. Because the DOI insures findability for the e-journal article, citation styles (APA, MLA, Chicago Manual of Style, Turabian, etc.) are starting to request the use of a DOI in a citation for e-journal content. Below are some methods that can be used to obtain DOIs
