Actually, I work at a public school district that has about 800 employees for 8,000 students and I help maintain the FIS/HRMS. Going back 10 years for this information would be pretty trivial for us. Our systems already have reports that do the above. The name, address, telephone, and personal email is basic demographic information in an HR system. Yes, I can imagine the kind of complexity that would arise in a 25 fold increase in personnel, but, if anything, the data systems would have more historical data in them. Financial records retention typically involves manually purging records rather than the opposite. After all, you've got to store at least two years of information just to be able to handle taxes and auditing. It's all saved in the system and date tracked appropriately. Going back longer than that would be difficult, but that's only due to records retention laws. We're not required to maintain most personnel records longer than about 7-8 years (though some go as long as 50 or more, such as the types of records that pensions require). Then again, I'm also familiar with FOIA requests, and I'm aware than at least 50% of the cost is probably going to be the cost for lawyers to vet the information before release.
