How current is the information contained on this site?
Check the bottom of the opening page of the site for an indication of when the site was last updated. Many now contain such a date, or at least a copyright indication that includes a year. If that year is not the current one, be cautious about using the information.
Some sites also include dates for other reasons (e.g., a performance schedule on a musician's web site). Such dates can also be good indicators of currency.
