Every era, ghost town, outlaw and historic-park page on this site is checked against primary and secondary published sources rather than written from memory. This page documents the kinds of sources used and, where a specific claim traces back to a named historical account, credits it directly.
How This Site Is Fact-Checked
Historical claims on this site are cross-checked against primary accounts where they survive, official government and state-park records, and established historical scholarship, not against other websites. Where a fact is genuinely disputed or unverifiable (folk etymology, contested legend, a since-corrected historical claim), the relevant page says so directly rather than presenting it as settled.

A Note on This Site's Own History
Much of the original documentation this site preserves and builds on traces back to the California Territorial Quarterly (published earlier as the Dogtown Territorial Quarterly), a Butte County regional history magazine that ran from 1990 into the 2000s, along with the work of the many contributing historians who wrote for it over the years. This site's editorial voice today is anonymous, but the underlying research it documented (much of it first-hand, some of it now otherwise hard to find) is worth acknowledging directly.

What was the Dogtown Territorial Quarterly?
The California Territorial Quarterly (originally the Dogtown Territorial Quarterly) was a Butte County regional history magazine published from 1990 into the 2000s. Much of the original historical documentation this site drew on traces back to that publication and its contributors.
Who was Ben C. Truman?
Major Ben C. Truman was the editor of the Los Angeles Star who personally interviewed Tiburcio Vásquez after his 1874 capture and wrote The Life, Adventures and Capture of Tiburcio Vasquez that same year — one of the primary sources behind our Vásquez page.
