I think I have found some typos in the libproj4 manual.
Page 96, under the headline "Oblique Stereographic using intermediate sphere":
* Equation (7.36) says "k)0", but the parenthesis does not match anything. I think it should have been "k_0" in the LaTeX source, so that the text would be "k0", with the zero as a subscript.
* Equation (7.37) reads
chi = ( cos c ... )
but something is missing. I looked in Snyder's book, and I think it should be
chi = asin( cos c ...)
(chi is that Greek letter that looks like a tall and narrow x, but isn't an x.)
Page 78, table 6.1: Lambert Conformal Conic, in the general formula for rho, there is a numerator
tan^n( pi/4 + phi1/2)
but in the case phi1 = phi2, the analoguous numerator is written as
tan^n( pi/4 + phi1) / 2
Should not these numerators be identical? They differ only in the placement of the ending parenthesis.
