Calhoun: The NPS Institutional Archive - Dudley Knox Library
Calhoun: The NPS Archive
Calhoun is the Naval Postgraduate School's digital repository for research materials and institutional publications created by the NPS community.
Calhoun is built for the purpose of making NPS-created scholarly content visible, searchable and freely available to the public. Contact us to get your NPS work into Calhoun.
Why should your NPS research work be in Calhoun? Three reasons.
- Your research is given broad exposure. Calhoun promotes visibility for your work. Content in Calhoun is indexed by Google Scholar and harvested by other repositories around the world.
- Your research is published under a stable link, now and in the future. Calhoun uses persistent "Handle" URLs, so links don't break.
- Your research is archived in one place, providing documentation you can use. It's easy to point to what you've worked on, advised, and published.
One more reason . . . . The library does all the work! We can do everything from locating to digitizing to cataloging your NPS work for preservation and visibility. Contact us to get your NPS work into Calhoun.
How can I get my NPS work into Calhoun?

I found an NPS Thesis for sale online. Is this legal?
It depends. If you are a US government employee, yes, entities such as vendors using amazon.com or other platforms may reformat it and sell it -- as long as they credit you as the author.
If you are a non-US federal government employee, probably NO, but IT DEPENDS on your contractual agreement with your employer/agency. Check with your legal counsel and they can issue a cease-and-desist if it is not appropriate. Read more about copyright as it applies to NPS students.
Can I get a list of all public release NPS thesis authors, titles, dates, abstracts, etc.?
Each quarter, we publish the metadata used by Calhoun for NPS theses, quarterly, in spreadsheet format.
Each set includes author names, titles, advisor names, departments, abstracts, service affiliations, degree names, and more.
Note: register for an account with Calhoun to download records from individual items, whole collections or search results.
Can I export a custom list of search results?
You must be registered for an account with Calhoun to export metadata from a collection or from a set of search results. To register for an account with Calhoun, look on the left for My Account > Register. It is not possible to download a selection of assorted records for export, currently.
How do I find lists of Thesis Abstracts?
Compilations of Thesis Abstracts from 2005 on are available in Calhoun. These compilations may list theses that ultimately were marked for limited distribution or received a classified status. Those documents are not llsted in the library catalog nor are they included in Calhoun.
How do I find a list of theses I advised?
Try this search in Calhoun:
Use double quotes around your own last name. Add your first name after your last name, within the double quotes, for more precision.
Note that Calhoun items are cataloged "from the document", meaning name variations are preserved just as they appeared on the original document.
You can sort the results list by date using the gear icon. The long url that results can be used as a link on any web page and will always show updated results when new items are added.
Why is it called "Calhoun"?
The name of the NPS Digital Archive honors Professor Guy K. Calhoun (1889-1920), professor of Mathematics and the first appointed -- and published -- NPS scholarly author.
This earliest known appointment for a Naval Postgraduate School professor occurred on May 6, 1910 when the 61st Congress approved Ensign Guy K. Calhoun as “professor of mathematics in the navy.” 
Following his 1908 graduation from the Naval Academy, Calhoun made extensive computations to develop a set of mathemathics tables that proved to be highly useful to navigators. His work, Products of Arcs and Sines of 15-Degree Rhumbs was published by the Government Printing Office in 1910. It remains in print to the present day.
Calhoun’s Congressional appointment – discovered by NPS Mathematics Department Chairman Carlos Borges – sheds new light on the process of faculty hiring at Annapolis. (At the time of his appointment, NPS was called the School of Marine Engineering and was co-located with the Naval Academy at Annapolis.)
We are proud to initiate NPS’s digital archive in the name of Professor Guy K. Calhoun. Calhoun Digital Archive serves as a permanent and secure online home for work produced by NPS faculty, scholarly work and other NPS-authored documents.

We welcome data in the Calhoun repository, and can add it to the same record that presents your published work. Explore our datasets collection.
We are aware that scholars may publish their data in various places, as desired, and Calhoun is one possibility, especially for data related to published works in Calhoun. We can publish your data ahead of publication, "in place" (if you would like a link to include in a work going to press); in the same record as the published work, or in a separate record apart from the work itself. We are glad to work with you.
