The Avery Index to Architecture Periodicals is very useful for finding articles about the buildings and projects on the UC campus.
Try typing University of California San Diego as a subject. When you find something that interests you check our catalog, ROGER for the availability and call number of the journal. Recent issues (a year old or less) may be found in the current periodical stacks; older issues are bound and shelved by call number order on the regular book stacks.
Also, as a source for local newspaper articles about UCSD try the Union-Tribune Archives, covering articles back to 1984.
Modern San Diego is also useful for general information on architecture and architects on the UCSD campus and the surrounding area.
