Each Congress starts numbering their legislation over again from #1. See the key on the attached sheet to see the abbreviation system for legislation used by Congress. Choose the correct Congress by number or year (i.e. 111th Congress – don’t see this? Google!) to find your legislation when searching.
Who was a) alive and b) in office in the House or Senate and voting on your legislation in both the earlier and later legislation? No easy way to do this, this is why you have two tabs with the earlier and later legislation up at the same time. Try to find 10 members of congress who voted on both pieces of legislation! Remember that legislation starts in the House and then goes to the Senate – usually under different names, you’ll need 5 of each (House and Senate).
