The Search OAC box is available at the top right-hand corner of every page on the website. Enter one or more search term to search through all the collections and items in the site, regardless of which page you are on.

Search Options
Enter the keywords you would like to search on. A search for two or more words will result in records containing all of the words (e.g., cat dog will get you results where both cat and dog appear).

• Exact Phrase:You must use quotes to search for an exact phrase (e.g., "gold rush" will find Gold Rush, but not gold jewelry).
• Case Sensitive:Searching is NOT case sensitive. Searching for History or history will yield the same results.

Our search does not support Boolean operators (AND, OR, NOT). However, entering a multiple keyword search will work like Boolean AND. Results will be returned only when ALL of the keywords appear. For example: sierra mining will retrieve items with both sierra and mining.

Collection guides (also called "finding aids") describe the items in a collection and how they were gathered or created. They also identify the collection's location, and may provide additional information, including detailed descriptions, chronologies, and biographies.

1. Tells you that some items in this collection have been digitized and can be viewed online. Click this link to see them all, or look for the eye icon in the Table of Contents to see where they are located in the guide
2. Tells you that none of the items described in this collection have been digitized. You will need to contact the institution to learn how you can view an item (click on the Contact link).
3. Links to the website of the institution that contributed the collection guide and owns the material. Contact the holding institution for any question related to the collection or its contents, including requests for duplication, permissions, or more information.
4. Some collection guides feature a Request Items button. If you see this button, you can use it to register with the institution that owns the collection and request materials from it. For example, you can obtain a scanned copy of an item that you are interested in viewing, submit a request in advance of a visit to the library or archive, or ask for additional information about the items in the collection. Upon registering with the institution, you can place requests and track your orders.

2. View entire collection guide lets you view a printable version of the full collection guide, with options to print/save as a PDF document.

When you click the yellow hits link, you will be taken directly to the results for your search term in that section.

The OAC does not own, store, or house any of the materials described in the collection guides, nor any of the digital materials appearing on this site.

The name of the contributing institution, as well as a link to its website, is provided on every collection guide and digital item (image or text). The following screenshots provide examples of where to find this information for the various types of materials on the OAC:
