Karen in CO Posted May 30, 2009 Share Posted May 30, 2009 I realized last night that all of our science encyclopedias are too young for my dd now. We were looking for an explanation of the lymphatic system, and none of them had it. Not even one picture of a lymph node. I need something meatier than our children's encyclopedias. What are your favorites? Thanks Quote Link to comment Share on other sites More sharing options...
