In some cases I made two copies of the original at different exposure settings to bring out different features on the same page. In many cases I left out duplicates of the same document if it appeared elsewhere in the binder. Because of fragility, odd sizes, tape, etc. I checked my copies carefully to make sure I captured all the material in each binder. I felt there was so much information on President Nixon available to the public that it was pointless to reproduce the articles, while the document on low-power television was lengthy and technical.
Mistakes are of course inevitable, given the huge volume of material.
I did try hard to do justice to Dad's collection and give it, if not immortality, at least redundancy and longevity. The thought of losing his original collection through fire or flood horrified me. The original Rubincam Family Ancestry is being retained by the Rubincam family for now. Rubincam Family Ancestry also differs from Rubincam Family Papers. Much of that collection consists of my father's correspondence, especially the voluminous exchange of letters between his cousin and best friend Amos Haines Troth II and himself.
