I'm also recommending that we discard the old Burton Legal Thesaurus. We had a newer one at one time, but it is gone.
I am recommending that we update Black's Law Dictionary (there is a new ed for $85), and all the Nolo titles (there are new editions for all and they are very affordable).
I am recommending that we keep everything else. The three constitutional law books have a lot of the same cases in them, but not all. Encyclopedia of the United Nations and International Agreements will never be used much, but it was donated by one of the authors, a local person, and it is an expensive set.
Let me know if you think we should discard anything else.
