As the the not for profit binoculars research website www.miniaturebinoculars.com has continued to grow (approaching 13,000 photos, probably around 800 or 900 screen pages, approaching 11 million page views) I have recently added a large research section of old and vintage catalogs of binoculars, and with the newest updates that I am posting this week (11/5/2018) I will have posted 1,155 scanned catalog pages of all types of binoculars from 83 different catalogs dating from 1913 to the 1970's, and showing a large number of brands and powers and types/patterns of binoculars (plus some monoculars, telescopes, spotting scopes, rifle scopes whenever they happen to have been in the catalogs). These are displayed as PDFs that can be accessed by the scroll down index pages "Research Materials #1", "Research Materials #2", and "Research materials #3", and are intended for anyone trying to research any old or vintage binoculars through primary source materials. These scans include distribution and manufacturer catalogs and brochures, and presently encompass US, UK, French, Italian, Australian, German and Japanese market materials. It is really hard to beat having open free access to original source materials, and even in this internet age it really hasn't been previously available for vintage binoculars. More vintage catalogs are being added as quickly as they can be purchased around the world at a reasonable cost, or are donated to the effort, or can be borrowed to be scanned for this effort. If anybody has pre-1980's catalogs or brochures of binoculars that should be included in this effort, please contact me through the website. Among some of the catalogs I would particularly like to add but that I can't seem to locate would be some pre-1980's Japanese and Spanish language binoculars catalogs, if anybody can help with that. I am already having good fun seeing how large and expansive I can make this resource, though the scanning itself is quite tedious.
