One method for many sheets is to make a sandwich.

Summary sheet at beginning of workbook.
Add a blank sheet to right of that sheet. . . name it First
Add a blank sheet at end . . . name it Last

Formula in Summary sheet =SUM(First!A1:Last!A1)

If need new sheets insert between First and Last

I would have thought this was easy but I can't find the answer. How to
I construct a formula to add across sheets, ie
=sum(Sheet2!A1+Sheet3!A1+Sheet4!A1) is the easy way but that gets
tedious if there are more than a few sheets. will
=sum(Sheet2:Sheet4!A1) work?

Thanks
