Vireo is a turnkey Electronic Thesis and Dissertation (ETD) Management System. It addresses all steps of the ETD process, from submission to approval by the graduate office to publication in one or more institutional repositories.

With Vireo, students submit their digital theses and dissertations via a simple online interface, while graduate offices can manage the ETD approval process behind the scenes. Institutions can also use Vireo to an institutional repository and/or create an export of theses and dissertations for submission to ProQuest.

The Texas Digital Library, in close collaboration with Texas A&M University, provided initial development of Vireo and released it under an open source license in 2010. The TDL and members of the Vireo Users Group continue to oversee development  of the application.

The Texas Digital Library also hosts Vireo as a service for its members.
