HistoGrafica: historical images and Web 2.0

Received an e-mail from someone named Agata Dras to take a look at a new site called HistoGrafica that features historical photographs and other kinds of pictures and utilizes some Web 2.0 technology to make them more relevant to the Flickr generation. While I thought the site was based in Latin or South America, it's actually hosted in Ireland of all places. The site's very well thought out and could evolve into an important focal point for historical images of specific geographic locations. Much if not all the images are sourced from public domain repositories such as the Library of Congress or WikiMedia. The developers are hoping that individuals and institutions will decide to add their own images, especially if they're out of copyright. Users will not necessarily be able to verify the accuracy of any information on the site, especially user comments.
