These resources are great for general searches. Much like the Discovery tool, ​WorldCat and Google Scholar search a wide range of materials across formats. If you're looking for an article or a book that Clark might not have, or want a different way to search for articles, these are the right resources to use.
The Dissertations section is slightly different -- it only searches dissertations/theses. If it is a Clark dissertation/thesis, you can find it in the non-cirulating Special Collections stacks. If it is not a Clark dissertation, we may not have access to it immediately.
Whether a general database, or a dissertation, if you find a resource Clark doesn't have that you want, send a request through Interlibrary Loan!
Search all library collections across all formats.
