"The idea of photocopying all the relevant documents was [an] impossibility, because of cost, time and travel constraints. [...] An off-hand remark to one of the staff at the Riksarkivet revealed that they not only allowed non-flash photography of their collections, but they even had a camera stand setup for the occasional photographing of maps and images that could not be photocopied. Gennari set about photographing 2,500 documents, producing some 25,000 images in total, which would have been the equivalent of $15,000 worth of photocopying. If he had used a film camera, almost 700 rolls of film (about $4,000) would have been required with the attendant costs of converting those to photo CDs adding $30,000 to the total costs). However, with the images safely stored on a handful of recordable DVDs Gennari was able to import the whole collection into Google's free Picasa image library software for cataloguing and study on his return to the US."
