As data repositories start to flourish, it is reasonable to ask questions such as what sort of chemistry can be found there and how can I find it? Here I give an updated[cite]10.1515/ci-2016-3-408[/cite] worked example of a digital repository search for chemical content and also pose an important issue for the chemistry domain.

I am at the ACS meeting, attending a session on chemistry and the Internet. This post was inspired by Chemicalize, a service offered by ChemAxon, which scans a post like this one, and identifies molecules named. I had previously used generic post taggers, which frankly did not work well in identifying chemical content. So this is by way of an experiment.
