DOI (Digital Object Identifier)

DOI has been used by the science, technology, and medical journal publishing industry for a long time, and now it is being rapidly adopted by other publishing industries.

A DOI is a unique identifying number for a scholarly article that is used to obtain information about the publication's location on the Internet.

By default, when clicking a CrossRef or DOI-link in a source, you'll be linked to the full text at the publisher's website. This may not be the appropriate copy. The Library may host the journal locally or subscribe to the journal via databases.

As a CrossRef library affiliate, the Library can direct users to our holdings via SFX when the users click a CrossRef or DOI-link. This is achieved by the DOI server recognizing the users from our institution.

A cookie has to be set on your browser that will enable you to connect to our library's OpenURL Resolver - SFX when looking for citations which use a DOI link. An easy way to set a cookie is to let the user's browser load a particular gif displayed on the web page:

There are several ways to search with DOIs:

• Append DOI to "http://dx.doi.org/". If you know the DOI of an article, simply append it to "http://dx.doi.org/" to make a link to search, e.g., http://dx.doi.org/10.1103/PhysRevE.62.1457
• Search DOI using Citation Linker
• Access DOI via databases, such as EI Compendex, Oxford Journals Online
