Progress in (G)CW factorization

The following table contains all the factorizations of (G)CW numbers which have been reported to me since 1st July 2000, with the exception that factors with fewer than 20 digits are omitted because they were so easy to find and there were so many of them.

The key to the abbreviations used in the "Method" column in each of the above table of files is:
Name   Algorithm
alg: Algebraic factorization
Aur: Aurifeuillean factorization
ECM: Elliptic Curve Method
GNFS: General Number Field Sieve
lookup: Look-up from an external table, most often www.factordb.com
MPQS: Multiple Polynomial Quadratic Sieve
P-1: Pollard's P-1 method
P+1: Williams' P+1 method
SIQS: Self-Initializing Multiple Polynomial Quadratic Sieve
SNFS: Special Number Field Sieve

The table below shows how many factors each contributor has reported since the date given in the column header.
