How do I request permission to cite an article?

Teachers and educational organizations may use the content on The OE for educational purposes only. They do not need to obtain permission to use site materials for classroom exercises or teacher workshops, but they must make proper attribution to both The Oregon Encyclopedia and the authors of the entries. Web site administrators may create a direct link to pages of The OE from their Web sites without obtaining permission from The OE.

Can I alter an entry for use in my classroom or publication?

The encyclopedia entries on The OE are copyrighted by the Oregon Historical Society or Portland State University. Altered entries may not be published or attributed to the Oregon Encyclopedia, the entry authors, or the Oregon Historical Society. Short excerpts from entries are allowed if they appear as quoted material and the author and The OE are identified as the source.

Altering the text, especially using AI, can introduce errors of fact and in understanding. The OHS Education staff has created curriculum materials for students of all grade levels, with recommendations for using history resources, including OE entries, in the classroom.
