Library-related Flickr Mashup

I have been desperately searching the net for an interesting Mashup involving Flickr and a library. Eventually I have settled on the State Library of New South Wales Flickr Mashup

Hagon P (2008), State Library of New South Wales Flickr Mashup, State Library New South Wales, viewed on 28 March 2010, http://www.paulhagon.com/blog/2008/10/01/state-library-of-new-south-wales-flickr-mashup/

Paul Hagon has developed a Mashup using historical images from Flickr commons and compares them with their modern day images on Google maps. He has worked for various National Museums and Libraries since 1999. At present Paul is a web develper who works at the National Library of Australia. The Library of New South Wales has joined the Flickr commons and Paul has developed this mashup for them. The website home page is fairly simple with a very brief description of what the site is about and some tabs at the top right of the page to home, blog, work, about and contact. By clicking on the "Check it Out" link you are taken to a new page which is divided into two halves. The left half is a Google map of New South Wales with little blue speech bubble links indicating which areas have archival photos.By clicking on one of these little links an archival picture of the place opens up, similtaneously a modern Googlemaps street view of the area will open up in the right half of the screen.

At present the number of areas covered is limited, as not a great number of photos have been geotagged. Paul states on his site anyone can go in and add tags so that eventually it will evolve into something useful over time. It is difficult to know how accurate the matching of the archival photos to the Google street view is. Some places have changed so completely that it is difficult to compare one photo to the other and there is no indication which direction the archival photo was taken from. A couple of Archival photos trialed had no corresponding modern street view.
Overall an interesting site to play around on but not particulary usable at the moment. I would be very interested to see the same mashup done by the State Library of Tasmania
