John,
While I agree that Wikipedia is a great source for information, no one should ever take what you may find there as "gospel"
The reason for this is that Wikipedia is a collaborative effort by the internet community (i.e. the very people who go to Wiki to seek knowledge).
Most posted there IS accurate but you don't want to be citing it as a source. Instead, use it as a "lead" to show you where (from the annotations there, if provided) to find the documented information you seek backed by authoritative sources.
Just as an example, if there was a Wiki entry for John McCoy explaining how you developed a strain of hybrid corn that was resistant to every known form of fungus that typically attacks the corn plant. I could come along and add additional information to your Wikipedia entry stating that in addition, you were related to McCoy family of the Hatfields and McCoys and that your great great grandfather was hanged for stealing horses shortly after the Civil War and that your grandmother missed the hanging since she was busy tending the family's bordello in St. Louis.
