CODA will be undergoing a major software upgrade over the holiday break. CaltechAUTHORS and CaltechTHESIS are expected to be unavailable from Sunday 12/23 through Tuesday 12/25. The smaller repositories (CaltechCONF, CaltechCampusPubs, CaltechOH (Oral Histories), CaltechLabNotes, and CaltechES (Engineering & Science)) will be unavailable for shorter periods during this same timeframe. In addition, all CODA repositories may be unstable through the end of the holiday break (1/1/2013), although they will be available for searching. All repositories will be closed to new submissions from Sunday 12/23 through Friday 12/28. If you are a graduate student and you absolutely must submit your thesis during this time, please email the CaltechTHESIS team (thesis AT library.caltech.edu) and we will make special arrangements.
