With Wikipedia showing increasing signs of ideological uniformity, I thought I should try to diversify my consumption of reference material. A potentially very useful tool for this purpose would be a "meta-encyclopedia", i.e. a place where users can find a list of all existing encyclopedia entries on a given topic. Questions:
1. Does something like this exist?
2. If not, what are the closest substitutes?
My current method is to simply do a Google search for the topic of interest followed by the word 'encyclopedia', e.g. 'comparative advantage encyclopedia'. This method is already quite useful, with a much lower false-positive rate than I would have expected, though I feel there's still considerable room for improvement.
