GeoSystems Engineering




Digital copies of the UC Berkeley Geotechnical Research Reports dating back through the 1960s are available online through the NISEE Earthquake Engineering Online Archive, at:

The Earthquake Engineering Online Archive NISEE e-Library ( The database is searchable by keywords, authors and other methods to assist in locating desired publications.

Despite the location of the repository, these research reports cover a wide range of geotechnical topics, not just earthquake related topics, and typically served to document in detail the doctoral research of students studying under Profs.
