A wiki is a good idea. Putting a Singlefile or similar all-in-one file in a repository and provide index numbers organised as a look-up table would also work for easy retrieval by a random research user. Both require some admin and more effort from the researchers.

I wish there was a hostable version of archive.is for near-zero maintenance. You just submit a URL over the internet and the web page is cached once along with a screenshot. Then, anyone can access the archived version. This can be done already with archive.is but we have no control over its future, which is critical for long-term dependable archiving.
