2. What’s the problem here? Locating dissertations Various formats, including emergence of electronic theses and dissertations (ETDs) Various online tools for identifying, and now with ETDs, accessing Physical 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

7. Search Options Comparison RILM, Music Index, and PQDT allow searching by specific fields and/or keywords anywhere RILM and PQDT include abstracts, so more data for keyword searches to search DDM only allows keywords anywhere does have an author index does have time-period index does allow searching of “all,” “completed,” or “in-progress” dissertations

18. Search Methodology Master 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

21. Analysis of anomalies/not-founds RILM and Music Index Not-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 DDM Depends heavily on whether school requires submission ProQuest Almost 100% find rate--one not found because “music” not listed in subject

22. Other data issues observed Degree notation varies by school and/or over time DMEd vs EdD Challenges in student-assigned metadata and findability Self-chosen keywords/subjects Often omit key information such as department

23. Electronic Theses & Dissertations Since late 1980s Many 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

24. ETD Sources Besides PQDT Thesis repositories Networked Digital Library of Theses and Dissertations CRL’s foreign dissertation collection Scholarly 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 Individual schools Institutional repositories Institutional ETD repositories
