More than a decade ago, my book sales saw a deep decline. The last profitable book was that of my Red River Lumber Company series. If the truth be known, if it had not been for the Walker heirs of Red River, I would have been doomed. Another example, released in 2002 , and considered by many as my best work was the Lassen County Almanac: An Historical Encyclopedia. Even with rave reviews it did not sale out until twenty years later. Ouch.
Yet, from time to time, I have been asked to reprint a book, especially Eagle Lake and Lake Almanor. That is a pricey proposition that is a doomed financial failure. After all, I would be competing myself since BookFinder.com and other entities have my used books listed.
There is a related subject–calendars. Calendars have also seen sharp decline. I struggle to sale fifty. When I first corroborated with the Lassen High School Graphic Arts in 1979, we published 500! While program ended in 1999, I resurrected it. In 2017 I had 100+ calendars produced and that number has been reduced to half.
