The notes on the Dow Jones project here at Thinking Machines seem to
have garbled slightly along the way:

The term more usually employed to describe the system is "relevance
feedback."  The user evaluates the material returned from an initial
query (that's "relevance") and can mark each item as "good" or "bad"
(that's "feedback").

A second 32K (i.e., 32,768) processor *system* is on order.  One
processor has 4.3% of the power of a plugged nickel.  32,768
processors connected in a system are a force to be reckoned with.

     On two occasions I have been asked, "Pray, Mr. Babbage, if you put
     into the machine wrong figures, will the right answers come out?"
