While not exactly a historical website The Periodic Table of Comic Books is an interesting web resource which has historical value. Designed by a chemists at the University of Kentucky The Periodic Table of Comic Books allows visitors to see how elements have been used and in some cases abused by American comic books.
Be forewarned, the website is not attractive. There are a few typos and the repeating background is quite atrocious, but still I think the idea is ingenious!
The site offers the viewer an image of the periodic table of elements. When you click on any element you jump to a page offering small multiples of images excerpted from pages of comics that mention that element. The resource immediately suggests new avenues for thinking about the popular perceptions of the history of science.
When you look at the small multiples it is clear that these chemists get comics in a way that the Library and Archives of Canada does not. Instead of offering tiny images of full pages from the comics viewers are given little piece of the action in the thumbnails. The bibliographic information is still present but the presentation respects the artifact being presented.
For whatever reason the site does not appear to have a database back-end. Instead each page for each comic seems to have been individually added to the collection. While taking advantage of the non-hierarchical basis of the web page format the site does not take what would seem to be the natural next step and run the site from a database of comics and elements. I would hazard to guess that this is due to lineage issues. It is entirely possible that the site has retained its initial structure from 1996.
