ELEM: How many encyclopedia sets?

[Maggi Rohde <maggi@INTRANET.ORG>]

To those of you still using print encyclopedias: How many sets do
you recommend having?  We have some old World Books (3 sets total)
and many others, several of which are older than me.  Sigh.  I want
to pitch them, but am feeling guilty that I won't have enough for
using with reference source lessons.  We do have access to online
encyclopedias through MEL and also some on CD.  Opinions from
experienced minds?
