I’m a little late on this one, but I wanted to quickly comment on a new project, perma.cc, which came across my internet last week. Essentially, this is a tool (currently in beta but hopefully live soon!) that will allow users to submit web links for sources they would like to cite in academic articles. These links would have permanent URLs created for them, and have snapshots taken of their content for preservation.
A blog post I read about this project notes that link rot is pervasive across government reports (http://freegovinfo.info/node/4005). I will also add that in my short time in academia I have encountered numerous dead or otherwise incorrect links. This has proven frustrating at times and I’m happy to see some of my favorite institutions joining together to build a much-needed tool to enable digitally sustainable scholarship. Link rot is real- now something is being done about it.
