Locating dissertationsVarious formats, including emergence of
electronic theses and dissertations (ETDs)Various online tools for identifying, and
now with ETDs, accessingPhysical and/or ETD copy of dissertation
may be deposited with Library, Department, Graduate School, and/or directly with UMI/ProQuest
Challenges of author-supplied content and metadata

Search MethodologyMaster lists of completed dissertations were
obtained from three school’s Musicology web sites
Musicology focus because of manageability and because DDM is somewhat more limited in scope than the other databases
General searches were conducted in each online resource to cast wide net for each school for PhD dissertations in musicology between 1979 and 2008
Search results were compared against master lists
Any dissertations not found in general searches were searched by name and/or title

Analysis of anomalies/not-founds
RILM and Music IndexNot-founds generally newest (3 years old
and newer)When necessary to find by name or title
was because key data such as full school name or degree information missing
DDMDepends heavily on whether school
requires submissionProQuest
Almost 100% find rate--one not found because “music” not listed in subject
Other data issues observed
Degree notation varies by school and/or over timeDMEd vs EdD
Challenges in student-assigned metadata and findabilitySelf-chosen keywords/subjectsOften omit key information such as department
Electronic Theses & DissertationsSince late 1980sMany universities now only accept
electronic copies (usually PDFs) of dissertations as the official format
University may have ETD repository and/or a general institutional repository OR may just house ETD with PQDT
Potentially many access points to the ETD beyond the ones already discussed
ETD Sources Besides PQDTThesis repositories
Networked Digital Library of Theses and Dissertations
CRL’s foreign dissertation collectionScholarly repositories/indexes
OpenDOAR (Directory of Open Access Repositories)
Google Scholar (working with PQDT)Country or topic-specific sources (not all ETDs,
not all music)Theses Canada Portal Music Theory Online Dissertation Index
