A collection exemplifying of english pottery dating between 1790 and 1860.
These pamphlets range from publication dates in the eighteenth, nineteenth and twentieth century, with the bulk published in the 1800s. Many of the books and pamphlets in this collection are listed in The Annals of Murder: a bibliography of books and pamphlets on American murders from Colonial times to 1900, compiled by Thomas M. McDade. The nineteenth-century pamphlets in this collection were drawn from the holdings of the Research Library of the New York State Historical Association (NYSHA) in Cooperstown, New York. NYSHA's collection of murder pamphlets contains 400 items published primarily in the 18th-19th centuries. These pamphlets document the changing perception of the murderer from a repentant sinner to a monstrous deviant.
This collection is one of the largest and finest on yellow fever anywhere in the world. It contains monographs and reprints, representing the development of medical thought on yellow fever over the course of a century and a half. It reflects the confusion of 18th-century physicians when confronted with a new and deadly malady; the static debates between contagionists and non-contagionists during the 19th century; early attempts to identify a bacterial agent; and the consequences of Walter Reed's discovery of a mosquito vector. It also provides a view into the panicked efforts of local, state, and national government to respond to yellow fever's introduction and to check its spread; and to religious leaders' fervent warnings of pestilence as punishment for public sins. The digitization of the Yellow Fever Collection is made possible through a generous gift from Ranlet and Beth Miner.
