A very in-depth article appeared in the October 11, 2016 edition of the Westword:

The article covers the history of BNSCP and the many projects BNSCP is involved in. The article was authored by Laura Shunk who did a very thorough job of researching and reporting on BNSCP. It is most definitely a recommended read.
