Africa Growth Pilot/Online self-paced course/Module 4/Through categories

First of all, there's the standard wiki way, which is there's a big list of lists of backlogs on Wikipedia, and it has a list of articles lacking references. This is a category of articles you can see here. There are some articles here that have been missing sources since as early as 2007. But you could go, you know, to more recent stuff and look for articles that are missing sources. There's a list here, for example, from December, you can click on that and find lots and lots of articles that are missing sources that maybe you would find a topic here that interests you, or that you feel you could help with, and you could go that way.

The articles here have already been identified as having unsourced statements. You would find the "citation needed" tag in these articles, so you could go there and see if you can maybe provide a source for that statement.
