About CPC

Connecting Presidential Collections (CPC) is a free centralized site for searching across presidential collections. The project is funded by the Institute of Museum and Library Services (IMLS) and housed at the University of Virginia’s Miller Center.

The CPC project sets out to solve two problems:

  • Currently, presidential materials are spread far and wide (geographically, technologically, and otherwise). This means researchers and learners must consult a large number and variety of resources if they are to have any hope of conducting comprehensive research, with no "map" to guide their way.
  • Presidential sites and libraries are often isolated and on their own to publicize their wonderful materials and make them easily available online. In the age of internet research, it's increasingly difficult to be a small fish in a gigantic pond.

The CPC project seeks to remedy these challenges by providing a centralized website where researchers and learners can search across presidential collections. Once a visitor has found what they're looking for using the CPC search, they are then directed to the partner's website to view the chosen item(s), thus directing web traffic back to the partner's original records and elevating visibility of these essential collections. The site uses a Solr index and a Blacklight user interface.

Frequently Asked Questions

What is CPC?

Connecting Presidential Collections is a website that collaborates with partners to create a place for users to search across presidential collections. Partners submit descriptive information about their presidential materials, and the CPC website brings together that metadata into one convenient research site, presidentialcollections.org.

The CPC website is one part of a broader grant project funded by the Institute of Museum and Library Services (IMLS) and the University of Virginia’s Miller Center. The project has four parts:

  1. The CPC website, which combines descriptive information from presidential collections so researchers and learners have easy centralized access;
  2. A catalog of presidential collections that will be used to help map out the location of collections and identify partner organizations;
  3. Educational materials to help empower partners and potential partners;
  4. A microfilm project to extract item-level metadata from select sets of presidential papers.

How does CPC work?

CPC works by partnering with sites, libraries, and museums that have collections focused on the U.S. presidents. The partners send us descriptive information about their collections, known as metadata. This information usually includes title, author, description, date, and a URL for each item in a collection. We then upload that metadata to give users one website to search across all the partner collections. Users can view search results and then click through to the partner website to see the digital items.

CPC seeks to serve two purposes: 1. Facilitate access to presidential content so researchers and learners can find it in one easy location, and 2. Direct researchers and learners to our partners’ wonderful content.

Can my organization submit a collection and become a partner?

Yes! If you work with an organization that houses a collection related to the presidency, contact us! We will schedule a time to receive data about your collection, fold that data into the site, and begin directing researchers to your site through the CPC search interface.

There are a few factors that help make a collection appropriate for CPC: First, it needs to relate, however loosely, to the presidency. Second, we need a way to receive digital information (“metadata”) about that collection. We can receive it in any number of ways [click here to learn more] and the metadata can be in any format. Not sure if you’d be a good fit? Not to worry! Get in touch with us—we’d love to start the conversation.

If you work with a project that is relevant but not yet ready to participate, please join our email list to receive updates. We are also working on creating and disseminating materials and resources to enable organizations to participate. We’d love to keep you updated—we’re here to help!

Want to be a partner? It’s easy! Contact us so we can start the conversation. We'll eventually need an export from your data system with basic pieces of information about the content (more robust = better!). Don’t have a data system? Never fear! We’re developing resources to help organizations like yours. Read more about the educational materials here.

Where does the CPC content come from?

It comes from our wonderful partners! CPC is an aggregator, which means it makes data from different sources searchable in one centralized place. Every item that you find on CPC comes from a partner organization. If you click through for more information about an object, you’ll find yourself on a partner’s website—that’s because one of our goals is to elevate the visibility of these partner organizations and their collections.

Metadata found on presidentialcollections.org is made available with a CC0 license. Items featured on this site may carry their own restrictions, please check with the item owners before using. Please consult the partner for more information and contact us if you believe an error has been made.

Who are your current partners?

We’re gradually adding partners as we build the CPC site. Read more about our partners here.
