Min/Max values in worksheets

I would like to find the minimum and maximum values for a particular item on several worksheets.

Is this possible?

For example: each day I create a new worksheet for that day. I record many values for each player on that day's worksheet. One of those values is each player's time for his 12 minute run.

Can I automatically look through all the worksheets to find the Personal Record for each player's 12 minute run?
