Every time I remember this series exists there's somehow 3 new books, but apparently they haven't actually gotten more frequent since the series began. The shortest gap was between the third and fourth book which both came out in 2009

I would like to know what those tracts were called, so I can avoid them

Did I read a misprint in a textbook or something and then spend years thinking it was "tubercluosis" and everyone else was getting it wrong

I feel special for having read two of those!

Hmm, maybe I should check out the Langlands Conjecture...

One of mine just started tasting terrible for a while
