DOI Finds Open Access Research - DML Central | Information and digital literacy in education via the digital path | Scoop.it
One of the best things to come out of Open Access Week was the oaDOI tool by Impactstory.

If you are unfamiliar with the DOI (Digital Object Identifier) system, it provides a unique identifier for published works, one that operates as a persistent link to those works. Using this identifier, researchers can search for the work in question using just the DOI by adding “doi.org/” to the front of it.
