A useful website for Dipterists which includes much of the information from the Dipterists Forum Start Pack, including lists of recommended literature to identify each family.

To get access to the Starter Pack, unpublished keys etc, you need to join Diperists Forum and register with the Dipterists Forum website. Wait for the moderator to update your status to "DF Members", then you have access to the members area. Log in to the site and follow the link to "Forums". Then follow the link to "Test Keys and Other Unpublished Material".
