The collection is open for research though some record types may be restricted. Note regarding yearbooks and publications: Yearbooks in our collections should only be used if they are not available at the County or State Libraries. Please ask researchers to check at those locations for the year(s) they need. If they are not available at those locations, then the Archives’ copies can be used. Publications and printed materials can also be found in historical collections. Check the card catalog under the school name or category (e.g. Yearbooks).
