"century will not be found"....this remark contains a typographical error. It should have said, " My point is that only a portion of everything that Brunswick published from the late 1800's to the early 21st century WILL be found in the "catalog" section of the website."
For all practical purposes, Brunswick never maintained archives of their catalog and sales literature. One family privately owned all of the catalogs and sales literature we find on the Brunswick website today. The process of preparing the vast collection for the website became very costly, and Brunswick finally decided to limit the overall effort. There was, of course, a lot of redundancy, so we today are very fortunate to have what we have, but there are blocks of time when the absence of a year or two make it very difficult for independent researchers to develop a comprehensive timeline which might ultimately write a complete history. An example would be the years during which Brunswick transitioned from composition balls to phenolic resin balls. Brunswick did not manufacture everything it sold under the Brunswick banner and sometimes the flagging viability of a critical vendor forced Brunswick to make changes it could not control. An uninterrupted timeline would be very valuable to an understanding of certain outcomes.
