I posted all the links I have organized so far for unit studies over on my other blog.  I have also posted a list of literature guides over there.  It is just easier to post really long list over there.  I can just copy and paste it into the entry.  I can also do it all in one post instead of a bunch of small ones.  So you can go here to see both list.  Homeschooling on a Budget  sorry to make you hop around like that.
