409 MINES & MINERAL RESOURCES

The Oregon Index was compiled by State Library staff and volunteers starting in the early 20th century and continuing to the mid-1980s. It contains over 700,000 cards with citations to articles published in Portland and Salem newspapers, magazines, book chapters, and more. Topics cover events and issues important to Oregon history and state government.

In some cases, the cards use archaic language that may have been considered appropriate in the context of the time when the citations were created, but may be jarring to library users today. The cards have been digitized and posted without altering the content.

The resources that are indexed may be, but are not necessarily, found in the State Library collections. Try searching the State Library Catalog or WorldCat for book, magazine, or newspaper titles, or contact us for assistance.
