All 32 volumes of the most recent edition of Encyclopedia Britanica can
be purchased on one CD-ROM. The cost is $150 but last summer I had an
offer to buy it for $100. I suppose this offer, expiring on October 15,
is available to all teachers. Call the toll-free number: 1-888-229-0437
or visit their web site: http://www.eb.com
