Sumproduct can only contain up to 30 array references...

That depends on how the data is set out on each sheet. But I would begin
this way:
1) On summary sheet in column A, enter names of all employees
2) Use a SUMPRODUCT formula to sum all the 33 sheets for each employer
Gives us more details and we can be more specific
happy new year

I have a workbook with 33 sheets representing 33 pay periods. I have a
list
of 3900 employees who were paid during the year. How can I summarize
the
data by employee to get a total for the year? Not every employee was
paid
every pay date.
