Some traditions are easy to trace. We know Gardner founded Wica.
We know Alex Saunders founded Alexandrian Wica.
We know that Starhawk founded Reclaiming Trad.

I invite folks to take a moment to identify the source of their particular tradition, note which texts would be useful for discussing it and dig down deep in order to generate a list of authors and primary sources that would be useful in reviewing a given path.

This is not just a book list- this is a collection of primary sources for specific traditions and the branches within those traditions.
