There are no rules that are that specific on where you need to keep them, but they need to be somewhere you can find them if the IRS or someone questions your records. In all the schools where I have been an officer, we have had a storage closet at school where we store things, and that's where our old financial records are kept. Sometimes the treasurer keeps the most recent closed year at her house to make it easy to look up 'how things were done last year.' But with online financial records, as long as the treasurer puts in a good, detailed description with deposit/check records, we have found that we rarely have to go back into the paper copies anymore.

Where are you suppose to keep your past treasury books and check requests and check books for past years? Can the president keep them in her house or does it have to be in the treasurers house?
