I was looking forward to the 2015 edition, but the site says the catalog is shut down. What a shame. I hope they create something to replace it. Dantes Catalogs
What were the contents of the DANTES catalog? Maybe DSST DSST | Get College Credit has the info you are looking for.
It had a huge list of distance learning degrees at the associates through doctorate levels from schools that participated in the Servicemember Opportunity Colleges program. It also had a great list of classes through those colleges that could be used to filled program requirements in other colleges. However, SOC went through a lot of changes to kick off this fiscal year and the need for the catalog appears to have gone away due to these changes. It was a useful tool. I found my MPH in it and used to point a lot of my Airmen to it for degree and class options.
