Is there any data source for the rotational axes of bodies in the solar system? I have found several right ascension and declination coordinates for the poles of bodies in the solar system, but there seems to be no comprehensive source that is easily uncovered with Google etc. containing any other than those of the planets and a handful of other bodies.

Most importantly i am missing them for the Moon, but i'd like them for all regular satellites and any other bodies if possible.
Collecting and reporting the requested information is the job of the IAU Working Group on Cartographic Coordinates and Rotational Elements. They issue reports every few years; the most recent report was in 2009. The report is currently available at usno.navy.mil and astrogeology.usgs.gov, and elsewhere. Table 1 provides data for the Sun and planets (including Pluto), table 2 for satellites, and table 3 for other solar system bodies.

The question asks specifically about the Moon. The Moon's orientation is hideously complex. I won't even begin to replicate the expression in table 2 of the cited report. The report specifically addresses the Moon's orientation, admitting that the expression in table 2 is approximate. The best source is an ephemeris such as JPL's Development Ephemeris. These data are available in the form of SPICE kernels.
