These pages list practically every source of information I have consulted since starting this project sometime in the late 1980s. Missing are probably hundreds of "touches" to web references where I procured minimal information about names, dates, places, and events. The majority of those passing searches involved finding bits of information at books.google,com, hathitrust.org, JSTOR and websites of countless companies companies like the Union Pacific, Norfolk Southern, BNSF, and the CN.
Obviously, anyone who has collected railroad certificates for awhile probably has tried to find information about companies and encountered railroad historical societies. I could probably spend hours trying to list all the websites of libraries, railfan sites, museums, and historical societies I've encountered over the years. I would say that the majority of those encounters proved fruitless for whatever I might have been attempting to discover. On the other hand, who knows how many of those brushes against information resulted in discovering some off-purpose bit of information that ultimately ended up somewhere in this project?
I know that typical collectors could not possibly care about these compilations. Still, I offer these lists to the rare individuals who might want reminders of where they might be able to find obscure information about certificates or specialties that interest them.
