The map comes from a collection of digital records which are available on-line at the PA Historical & Museum Commission: http://www.portal.state.pa.us/portal/server.pt?open=512&objID=2887&&PageID=383882&level=2&parentCommID=2887&menuLevel=Level_2&mode=2 Other digital collections include: ARIAS (the Archives Records Information Access System) Doc Heritage Land Records Vital Statistics Military Records Agricultural Census of 1850 I find this site difficult to use. I find lots of useful information but often stumble across it by accident. Does anyone have any helpful suggestions on more easily navigating this site? For example, I was looking at Land Record indexes this morning. It took me quite a while until I found the actually images of the land surveys that were referred to in the indexes. http://www.phmc.state.pa.us/bah/dam/rg/di/r17-522WhitesideMaps/r017-522WhitesideMapInterface.htm#melish-whiteside (The main index for the available county maps). "The maps were the result of the work of John Melish, a geographer, traveler, and entrepeneur who convinced the Pennsylvania legislature to fund this ambitious cartographic project. Under enabling legislation passed on March 19, 1816, a number of deputy surveyors spread out across the Commonwealth. Over the ensuing years, these surveyors would produce maps for each county, which could then be assembled into a full and accurate map of the state. The deputy surveyors handed over their completed maps to the surveyor general, who in turn sent the maps to Melish for copying and engraving. But before these maps were delivered, a clerk made an office copy of the original. The first clerk to execute these copies was named John Whiteside, and since his signature appears on these versions, they have become known as the “Whiteside Maps” (several copies were also rendered by a Dan Small). Melish submitted his completed Pennsylvania map to the legislature in March 1822, which overwhelmingly approved his work, claiming the map was “an exquisite specimen of graphic skill,” and well worth the $29,276.75 spent on the project." > > > Wonderful map, many thanks....what is the reference Melish-Whiteside > Maps
