Re: Reference works are needed, Timing

There exists a reference work, in one sense, the archives of mathgroup.
If someone or a group would remove headers, clean it up a bit, index and 
(press a cd? post to MathSource? searchable URL?) distribute it would 
benefit everyone who uses Mathematica.
  Until I had to work on a problem, I didn't pay much attention to the 
functions of columns discussion, but found DataManipulation in the 
Statistics package with most of the functionality needed.
  Timing as a criterion for efficiency can't be matched.  When a function 
I had written didn't work in a reasonable time, examining the timing 
exposed the flaw.  Timing as a criterion for elegance is of less 
importance to me; readablity, or understand-ability is what I need to 
apply the techniques discussed to my work.  In the five years I've used 
the program, the speed of the machine I work on has gone from 261 seconds 
to 10 seconds for the same calculation, with 5 seconds or less for the 
machine coming this fall.
