I put the prints in a plastic page protector, two prints back-to-back in each. Info sheets goes between prints. Page protectors go into a regular 3-ring binder. That's how I store my negatives and contact sheets (PrintFile negative1/contact sheet1/contact sheet2/PrintFile negative 2). I'll type up a cover page with the date of the exchange and insert it at the beginning of each round.
