There are extensive written resources that I used during the research and writing of this guidebook. While I tried to include as much information as possible, the guidebook only begins to skim the rich history of the Rogue River. If you choose to dig deeper, these sources will round out your Rogue River knowledge. Check with you local bookseller first. If they don't have the title available, www.abesbooks.com is a great source to find used and out of print books.
