Map Monday!
Oceanside, CA.
At NARA-Riverside, we really like maps. A lot.
In 1450, Venetian monk Fra Mauro created what cartography experts say may be the first known “modern” world map. Two hundred fifty years later, a copy was made that now resides in the cartographic collection of the British Library.
But this map is interesting for reasons beyond its age. As Brain Pickings’ Maria Popova notes, this global depiction was created during the golden age of display maps, “the period between 1450 and 1800, when maps were as much a practical tool for navigation as they were works of art and affirmations of cultural hegemony or social status.”
In other words, these ancient maps often served as forms of propaganda (some would argue that most maps still do); and in a collection entitled Magnificent Maps: Power, Propaganda and Art, British Library cartography curators Peter Barber and Tom Harper explain the various ways that this and other ancient maps were used for reasons other than their sheer navigational utility:
[The Fra Mauro World Map (right)] points south because 15th-century compasses were south-pointing. It shows the Portuguese discoveries in Africa and questioned the authority of medieval and classical sources. Intended for display in Venice, it emphasizes the feats of Marco Polo. The British East India Company commissioned this copy, thus implying that Britain was heir to the Portuguese empire.
A hi-res version of the map can be found here, but those looking for an even more incisive look at the map and its history should check out this outstanding interactive applet, hosted by The British Library. [Spotted on Brain Pickings]

“Outline Map of Portion of San Bernardino Basin of Santa Ana River Drainage for use in Hydrographic Investigations”
These survey maps are held in a series of records created by the Surveyor General of Arizona, Frank S. Ingalls, near the end of the 19th century.
In 1891, the U.S. Congress created the Court of Private Land Claims to decide land rights cases for persons whose land rights were affected by the Gadsden Purchase and the Treaty of Guadalupe Hildago. In order to maintain ownership of the land, the petitioner would have to prove that he had been granted the land by Mexican or Spanish authorities before the end of the Mexican American War. The survey maps show the areas that two parties were attempting to prove ownership of, with indications of major markers such as springs and mining areas.
Happy Birthday, Yellowstone National Park!
Just 32 days left until the release of the 1940 Census…
It’s also the 140th birthday of Yellowstone National Park! The park was included in the many enumeration maps made for the 1940 census.
These maps are important because the 1940 Census does not have a name index. To search for a family, you will need to know the address where they lived.
If you have the address of an ancestor from 1940, find the address on the map and then look for the enumeration district number for that address. The ED number may be a two part number separated by a hyphen. The first number represents the county number and the second number the number of the enumeration district within that county.
Save the enumeration district numbers for the opening of the 1940 Census on April 2, 2012. You will be able to search the digitized copies of the census by ED number and then browse for your family members’ census entry.
