Citations for individual records in CODA (including CaltechAUTHORS and CaltechTHESIS) can't be downloaded from the actual item information page. In order to download a citation, perform a search, or navigate to a Browse page. From those pages, there are options to download citations in various formats. Near the top there is an "Export As" box with choices for downloading citations in various formats such as BibTeX, EndNote, and Reference Manager (RIS, compatible with Zotero, RefWorks, and other citation managers).
