<p>"Schools and Affiliates
…
Affiliates of the university are …and Barnard College (founded 1889, incorporated into the university 1900). "</p>
<p>The point of confusion, as a technical matter, is: what does it mean to be an “affiliate” in this case? What does it mean to be incorporated into the university as an affiliate? To which there is complete ambiguity; therefore spun in every direction.</p>
<p>For practical purposes, my understanding is the schools are quite closely integrated into the overall life of the university. Whatever “affiliate” is spun to mean, or even actually means.</p>
