  In this paper we determine the quadratic points on the modular curves X_0(N),
where the curve is non-hyperelliptic, the genus is 3, 4 or 5, and the
Mordell--Weil group of J_0(N) is finite. The values of N are 34, 38, 42, 44,
45, 51, 52, 54, 55, 56, 63, 64, 72, 75, 81.
  As well as determining the non-cuspidal quadratic points, we give the
j-invariants of the elliptic curves parametrized by those points, and determine
if they have complex multiplication or are quadratic \Q-curves.
