"Beginning with the January 2004 degree conferral, graduate students at Cornell University have had the option of submitting theses and dissertations electronically. Any thesis submitted electronically is then deposited in Cornell's Institutional Repository (eCommons). The student retains ownership of the copyright of their work. Students have the option of posting their work in either an open or closed community in eCommons (the default choice is the closed community). The open community is 'open access' ie the full text of the document is open to anyone in the world to download and read. In the closed community, only metadata is publicly available. Students can post to the closed community for a period of one, two, three, four, or five years with renewal possible but after 5 years the work is automatically moved to the open community unless a renewal is granted by the Graduate School after a request by the author. In general older thesis and dissertations from Cornell University are not currently available as digital files, but the Library is willing to scan and make available your Cornell Dissertation or Thesis in the open community digital versions on a cost recovery basis."
