  A large number of X-ray sources in globular clusters of galaxies other than
the Milky Way has been found with Chandra. We discuss three issues relating to
these sources. The X-ray luminosity function (XLF) of the sources in globular
clusters of M31 is marginally compatible with the XLF of globular clusters of
the Milky Way. The individual XLFs of a dozen elliptical galaxies, after
correction for incompleteness, are compatible with one another and show no
break; however, the XLF found by adding the individual XLFs of elliptical
galaxies has a break at L_x about 5x10(38) ergs/s. For the moment there is no
evidence for a difference between the XLFs of sources inside and outside
globular clusters of elliptical galaxies. It is not (yet?) possible to decide
which fraction of low-mass X-ray binaries in elliptical galaxies outside
globular clusters have formed inside globular clusters.
