Our current collaborations range from consulting, research, and development on well-defined projects to more general exchanges of ideas. We pursue joint research projects (e.g., with Cultural Heritage Language Technologies, the Digital Knowledge Center at Johns Hopkins). We serve as non-exclusive publishers for content that others have prepared (e.g., the Duke Databank of Documentary Papyri). We help projects develop their own materials (e.g., Civil War Newspapers). We help develop new collections for third parties (e.g., Archimedes). We provide digital library software and infrastructure for other collections (e.g., the Confessions of Augustine). While we have provided free technical support for particularly interesting collaborations (e.g., the digital library system for the Center for Hellenic Studies' Multitext Homer), most collaborations mentioned here involve formal agreements.
