This site supports six content formats for each feed provided. The formats are JSON, Markdown, HTML, HTML include, BibTeX and RSS. The easiest to use is probably HTML include. You can cut and paste the version into an existing webpage as is. It is however not terribly flexible beyond inserting into an existing web page and styling the CSS classes and attributes.
This site aggregates content from Caltech Library repositories.
Each repository system also breaks down its publications into types. E.g CaltechAUTHORS hosts articles, books and book sections, conference proceedings publication types; CaltechTHESIS includes thesis and dissertations; CaltechDATA hosts dataset and source code associated with groups and individual do research at Caltech. We provide a one stop shop for content and format (e.g. we include JSON versions of all the content we harvest). For each individual repository we provided a combined view of the contents types as well as individual aggregations of types. We provide this grouped by both Caltech People and Groups.
