All information is open to verification and revision in light of new facts. One advantage of Wikipedia is that anyone can edit it. If you see a problem with an entry, edit it and be prepared to defend that edit with facts. On the whole this model seems to be working remarkably well. On balance I think the quality and volume of information that is available in one place outweighs the inaccuracies that are sure to emerge from time to time from reference to inadequate or inaccurate sources.
