Just wanted to post some links here to a couple of items on Google Books that are useful for the study of Macrobius.
Ludwig von Jan’s edition of Macrobius’ Works (2 voll., 1848-52):
Volume 1
Volume 2
The older Teubner edition of the text, ed. Eyssenhardt, here (There is also a newer Teubner edition, ed. J. Willis, but not available on Google Books.)
