I've finally noted a list of the 73 books I bought last night. At one point, I thought of posting them here, but my guess is that anyone's interest but mine would quickly lag.
A few items come to mind, though.
For example, I bought:
Robert W. Chambers, The Common Law, New York, D. Appleton and Company, August 1911
-- and found later it contained many illustrations by Charles Dana Gibson. Moreover, it was dedicated to Gibson. Sweet!
Of most comics interest was probably a beat-up copy of:
Palmer Cox, The Brownies Kind Deed Stories and Sketches for Young Readers with Pictures Specially Designed to Please the Little Ones, Chicago: W. B. Conkey Company, 1903
I found it intriguing because there was work therein by other contributors in addition to Cox. (Visitors to the Geppi Entertainment Museum in Baltimore will know that Cox was a pioneer in the world of licensed pop culture, thanks to his Brownies.)
