"Hypergeometric Series Acceleration Via the WZ Method",

Tewodros Amdeberhan and Doron Zeilberger

Elect. J. Combin., Vol. 4, (2) 1997 [Wilf Festschrifft Volume].

This comes with a small Maple Package accel, you need also download EKHAD.

Greg Fee and Simon Plouffe used a formula that appeared at the end of the paper to calculate Zeta(3) to 13/25 million digits.

Most recently, Shigeru Kondo and Xavier Gourdon found a precision to more than <A HREF="http://www.lacim.uqam.ca/pi/records.html"> </A> 600 million digits, holding the present record!

See also Xavier Gourdon's Constant page with its interesting comparisons of computational complexities.
