Dissertations and theses in Computer Science can be searched across institutions using ACM Digital Library and ProQuest Dissertations and Theses.
Many academic institutions host their own repositories of faculty and student research. In addition to dissertations and theses, institutional repositories often contain technical reports, datasets, conference papers and other files associated with conference presentations. The following is a list of some of the more robust institutional Computer Science repositories.
Another resource of note in this vein is SODA, a Computer Science research repository maintained by the four software institutes constituting the Swedish ICT group.
Repositories of dissertations and theses submitted by PhD and masters students are good places to survey pre-publication research. Dissertations are usually very narrowly-focused thorough and in-depth explorations of a topic. Dissertations and theses are also excellent bibliography-mining territory. Because submitters of Masters and PhD theses and dissertations are required to conduct a comprehensive survey of the existing literature relevant to their question, these documents often contain useful literature reviews and contain meticulously compiled bibliographies.
