Digital Object Identifiers

Digital Object Identifiers (DOIs) are persistent identifiers which can be used to consistently and accurately reference digital objects and/or content. The DOIs provide a way for the ADS resources to be cited in a similar fashion to traditional scholarly materials. More information on DOIs at the ADS can be found on our help page.

Citing DOIs

DOIs should be the last element in a citation irrespective of the format used. The DOI citation should begin with "doi:" in lowercase followed by the DOI with no spaces between the ":" and the DOI.

doi:10.5284/100000

DOIs can also be cited as a persistent link from another Web page. This is done by appending the DOI Resolver with the DOI. This would look like:

http://dx.doi.org/10.5284/1000000

However, if it is possible it is best to hide the URL in the href property of the <a> tag and have the link text be of the form doi:10.5284/1000000. The HTML for this would look like:

<a href="http://dx.doi.org/10.5284/1000000">doi:10.5284/1000000</a>
