Oregon is #42 in my state list. Many counties don’t have histories accessible online, but be sure to look at the STATE list, as there ae several entries that cover multiple counties.

FAQ

1. While every county in the state is listed, links are only provided for titles that no longer fall under U.S. copyright laws. All (almost) links connect to free websites.
2. There are a few instances when a book has been digitized, but is only found on a paid site. In that case, no link is inserted, but a note as to the website where it has been found is given.
3. When a state history has also been found in digital format, it is listed in the STATE section that precedes the county list. I have limited STATE entries to those with county histories/biographical volumes in them.
4. There are a number of counties that DO have histories written, BUT they remain copyrighted material. Therefore, if a county has NONE after its name, it doesn’t mean there is no county history, just that none has been digitized. It’s also possible that the only digitized county history is included in one of the state volumes, so be sure to check those entries.
5. If the book is on FamilySearch, you will need a free account to access it. This list does NOT include town histories.
6. When all fifty states have been completed, I will post a PDF of them all.
7. One last note – it is very possible that a book is digitally available on more than one website. I’ve only included links to one site per book.
