Wikipedia is hardly the definitive reference. SEO comes to mind.
The following was one of the best I've seen, where Dr. Adler is asked
to explain why his reference implementation differs from Wikipedia:
This is going out the Mr. Adler, his friends at zlib,
the related newsgroups comp.compression and
sci.crypt, and the newsgroups sci.math and
sci.math.num-analysis... This post relates to
suspect calculations... The algorithm is described
in the last parts of RFC 1950 and at its Wikipedia
page (http://en.wikipedia.org/wiki/Adler-32). [1]
