What is standard record-keeping like for a journal editor?
These days editors don't do much paperwork because the editorial management system (EMS) does it for them. The EMS logs all actions, sends automated reminders to reviewers, informs the editor when a review is submitted, and so on. It is usable by multiple people, and an editor with sufficiently advanced permissions can see what other editors are doing or even override them.
There's a list of free &amp; open source EMSes here, don't know if it's applicable for your situation.
