Activate Format|Cells|Custom then select mm/dd/yy or something similar and change it to the desired format.

The format option did not work. Is there a wildcard that I can use in Find & Replace that will look for every cell containg **/**/96 and replace then with 1996? I tried asterisks and question marks, but neither one worked.

It works for me.
Try again. Select a date format and change it to yyyy in the box for "Type".
Another option is:
Insert another column next to your dates column.
Lets say that you have dates in A from A2 on.
In B2 enter: =YEAR(A2) and copy down as far as needed.
Select all of the cells of B, copy the selected range, and execute Edit|Paste Special ->Values in place. Delete column A.
