Chick on "archive." Enter "erskine' into the search box, and all 285 maps in the collection will come up.
For the period of the American Revolution, The New-York Historical Society holds a significant number of maps. Chief among them is the series of field sketches and finished maps of projected battle sites in New York, New Jersey, Connecticut, and Pennsylvania begun by Robert Erskine, geographer and surveyor-general to the Continental Army, and completed by his successor, Simeon De Witt. The Erskine- De Witt series culminates with the detailed Winter-Cantonment of the American Army and it's [sic] Vicinity for 1783, which shows the final encampment of the Continental forces at New Windsor, New York, during the winter of 1782-83.

Websters' Instrument Makers Database
This database of instrument makers, or more precisely of their signatures, is a product of many years of research by Roderick and Marjorie Webster, longtime curators of the collection of scientific instruments at Chicago's Adler Planetarium & Astronomy Museum.
The Adler has the finest such collection in the western hemisphere, but when the Websters arrived in the early 1960s as volunteer curators the Adler collection had long been neglected. They quickly took up the serious study of scientific instruments, traveling widely to study and photograph instruments in other collections. In their travels the Websters took copious notes about the instrument makers whose work they encountered.
Realizing early the benefits of computerization, they acquired a Vector Graphics microcomputer and commissioned a custom database into which they could enter the information and notes they had accumulated on instrument makers. This custom database was later converted to the MS-DOS operating system, and was updated in that form until Rod Webster's death in 1997. In 2001 Madge Webster formally gave the database to the Adler Planetarium.
Data have been extracted from the custom database by Bill Burns (ftldesign.com), who is in no way responsible for any errors that exist in the data. We are grateful for his generous assistance. This project seems to us an example of the merits of distributing free (to you) or low-cost (to us) information on the Web.
The presentation of these data could be improved in many ways, mostly involving money or time which is not available. Take this for what it is: a work in progress and a guide to research, rather than an authoritative reference. We welcome additions or corrections, which may be submitted directly from Database Search Form.
