Essays on the Study of Pegmatites  is a series of informal articles that present my comments on historical papers in this field. Most of the publications would be familiar to anyone who has studied the literature of pegmatites. A few of the articles are obscure, but they have contributed in some important way to my own understanding. My goal is to extract the significant content that each article contains and discuss it in the context of the informal essay. I will seek to make clear why each paper is worthy of a detailed read. Some of that information is factual, some conceptual, and some inferential, by which I mean the sometimes veiled messages of some authors that gave me insight into their thoughts. Most of the historical works are not well known nor readily accessible to the many amateur scientists, graduate students, miners, mineral collectors, and other aficionados of pegmatites who follow the PIG webpage. I will post PDF copies of the papers for which I can get permission. In some cases, I will be able to provide links to purchase articles. Those who have access to interlibrary loan services can acquire most of them in that way.
