Here‘s a cool web feature for lit types. Clicking the map (the image above is a detail) takes you to a section of an 1859 map of London. Once at the map detail you can get further information about that part of town. For example, you can click a “dictionary” button, which takes you to a description of that location taken from the 1879 Dickens’s Dictionary of London by Charles Dickens Jr. Or you can see an aerial photo of the area today, from Google maps.
The site is the brainchild of David Perdue. It’s a good illustration of how disparate data can be related to create, in effect, new content. Nice job!
