We have an assortment of 30+ phone books, and 7 of 'em from 1939-1956 are state wide (the yellow pages are Reno). In 1957 Bell stopped issuing State Wide phone books.

McDermitt wouldn't have had much of a phone book, as they only had from 7-9 listings from 1939-1952! In 1957 McDermitt was still included in the Reno/Sparks/Carson City phone book...and McDermitt was up to 45 listings!

We also have an assortment of LV, Reno, Laughlin and small town Nevada phone books.

Glad I could help with the research. Reading the old phone books is fun!
