Sara,

I have not used the "file extension" version to tell HT I want JSON
results, but if I take your first URL and change it to

http://catalog.hathitrust.org/api/volumes/brief/json/oclc:3967141?callback=mycallbackfunction

(insert /json/ after /brief instead of tacking it on as an extension) I get
a proper JavaScript/JSONP response.

For your second example, it looks like there's a PHP error message being
output that prevents the result from being
properly formatted JavaScript.  But afaict, everything on your end with
that request is OK.

cheers,

AC
