As I have looked through the base packages trying to decide which package would be best for me, I have noticed that there isn't a package geared specifically towards us reformed folks. In order to avoid confusion allow me to define what I mean by Reformed. That is those who hold to either the three forms of unity (the Belgic Confession, the Canons of Dort, and the Heidelberg Catechism), or the Westminster Confession of Faith. The base packages that are currently available are Protestant packages, but they aren't Reformed.
A Reformed package would be useful because I wouldn't then ended up purchasing a package with a lot of books that I may never use.
