The National Library of Ireland has launched a digitized version of the Shemus Cartoon Collection. “In December 2006 the National Library of Ireland acquired some 250 original drawings of the Shemus cartoons that appeared in the Freeman’s Journal between 1920 and 1924, the final years of that old and distinguished Irish newspaper. … These cartoons are remarkably hard-hitting comments on the events of this bitterly contested period in Irish history.”

The Alaska Satellite Facility Distributed Active Archive Center has released a new collection of 1978 data from NASA’s Seasat satellite. “The new downloadable digital imagery will enable scientists to travel back in time for research on oceans, sea ice, volcanoes, forests, land cover, glaciers and more…. SAR bounces a microwave radar signal off the surface of Earth to detect physical properties, including surface roughness….Until now, Seasat SAR data was archived on magnetic tapes, and images processed from the tapes were available only as optical images of film strips or scanned digital images. Neither the tapes nor the film allow the quantitative analysis possible with the new digital archive. It was also not possible to use the tape media on which the limited set of initial digital imagery was recorded.” (The whole article gives a lot more detail; having a little trouble wrapping my head around Seasat, thus the extensive quotes.)

You’ve heard of the magazine The New Yorker, right? Did you know there was one called The Chicagoan? It’s not around any more but its 1926-1935 run has been mostly digitized and made available online. Good afternoon, Internet…
