Collectives, Directories, and OA Book Publishing Initiatives  

ETDs (Electronic Theses and Dissertations)

Alexandria Digital Research Library (ADRL)

UCSB's open access theses and disserations

eScholarship  

UC's institutional repository and journal publishing platform. Not all campuses have ETDs in eScholarship. Due to copyright restrictions and the need to obtain permissions from authors, not all years are available online. UC campuses began accepting ETD submissions different years. For details see ETD Preservation and Access Sevice: California Digital Library. UCSB's open access ETDS are in ADRL (Alexandric Digital Research Library). 

Networked Digital Library of Theses and Dissertations (NDLTD)

The NDLTD is an international organization promoting the adoption, creation, use, dissemination, and preservation of electronic theses and dissertations (ETDs).  In addition to providing full-text access to ETDs, the website includes  information for university administrators, librarians, faculty, students, and the general public on how to find, create, and preserve ETDs; how to set up an ETD program; legal and technical questions; and the latest news and research in the ETD community.

PQDT Open

The PDQT Open database provides full text access to PDFs of dissertations and theses. The authors have opted for open access publishing through the ProQuest Open Access Publishing PLUS program.
