This interactive map shows the location of every single cargo ship over the course of 2012. Shipping routes (the Straits of Malacca look particularly bottlenecked) and materials shipped are available via the interface, and there’s a nice narrated tutorial explaining how the map works. Thanks to David Krathwohl for the tip. [Digg]
Speaking of the Library of Congress, yesterday it opened a new exhibition both online and at the Library’s North Exhibition Gallery. Mapping a Growing Nation: From Independence to Statehood features the best known copy of Abel Buell’s 1784 New and Correct Map of the United States of North America—“which, among other things, has been recognized as the very first map of the newly independent United States to be compiled, printed, and published in America by an American. Additionally, the 1784 publication is the first map to be copyrighted in the United States, registered under the auspices of the Connecticut State Assembly.” Accompanying Buell’s map are other early maps—often the first maps—of each U.S. state; the maps will rotate on and off physical display for space reasons but will eventually all be featured online.

The Library of Congress blog’s series on maps of imaginary places has now concluded; the final post is a look at what’s available on the subject from the Library of Congress itself. One interesting nugget of information: “The Library of Congress classification system has a range of call numbers reserved for maps of imaginary places: G9930-G9979.” How about that.
