An interesting new resource (currently in beta) for discovery of articles/papers:
https://www.semanticscholar.org
Their current corpus consists only of computer science papers they say, but some basic searches suggest that this is still broad in scope and is relevant to folks who are working with Drupal. For example, I was interested to see what papers might be found regarding the realm of the semantic web and linked data. It turns out that a search on 'drupal linked data' yields 498 papers from the default date range of 1985-2015:

An example of a paper that caught my eye, entitled CMSs, Linked Data and Semantics: A Linked Data Mashup over Drupal for Personalized Search:
