I went to more than two of the websites because a few didn’t seem to be recently updated and I was just curious.
Pleiades
This site seemed really interesting for anyone interested in history and places (which I am), but it did seem targeted toward a very specific audience.
The site has compiled tons of places, locations, and place names mentioned in Ancient texts and put them on a modern map, including time periods. This seems to be a very useful tool for a variety of scholars, especially since all the data is open access. If I was a classics scholar or involved in sociology, archaeology, or other fields that dealt with the ancient world, this site would be incredibly useful and interesting.
British Museum
This site is the website for the British Museum. It is a very well-done website with scrolling images of their collections. However, the organization is a little interesting — it seems like they web designers were trying to fancier than they were trying to be practical or informative).
What is the difference between a “website” and a digital humanities project?
I think that a digital humanities project (at least from what I could see) tend to have a very specific audience and they have a very specific purpose. Now a website has those things to, but they tend to be more informative (cf. British Museum) and not geared toward analyzing anything in particular. The analysis of data (of whatever kind) or at least compiling a large chunk of information into one place seems to be the goal of many digital humanities sites. To me, it seems like they are open access databases on steroids. Another common factor is that these DH projects seem to be housed at universities, so they would therefore be assumed to serve a scholarly aim, while websites do not have such high ambitions.
What dimensions does [your website] have that distinguishes it?
The Pleaides is a digital humanities project since it compiles a wide range of data and uses that data to map out points of real places that existed, which have now been superimposed on a modern map. Again, this project seems to be geared toward a very specific audience. On the other hand, the British Museum site is for a general audience and does not have a particular scholarly focus.
