The DOI (Digital Object Identifier) is a persistent identifier used in the scholarly literature to uniquely and durably identify a digital publication (e.g., article, whole issue, monograph, conference proceedings, poster, thesis). 

The use of DOI allows digital content to be tracked on the network through DOI resolver services, which redirect to the digital resource. 

DOI can be used to simplify citations. Antepending the string http://dx.doi.org/[DOI] to the DOI generates an active link that can be carried over into the bibliographic citation.

All AlmaDL publication services guarantee DOI attribution, thanks to adherence to the DOI Project promoted by CRUI.
