According to Wikipedia:

"The "modern" World Series has been an annual event since 1903. Baseball has employed various championship formulas since the 1860s."

I guess that means the 1886 event was a championship and technically a "World Series," but not exactly viewed in the same light as the World Series contests which started in 1903.

Whatever the case, that sure is a lot of errors.
