I'd add that you should be open to accepting that some of those things
STILL won't make sense once you know why librarians do things the way
Much of what we do indeed simply doesn't make sense -- I mean, we got
here somehow for certain reasons, and understanding the history can help
understand how we got to where we are, but often where we are is really
really unfortunate. (And even many of us librarians don't entirely
understand how we got here, if we're under a certain age!)
But anyway, you've probably already seen it, but Jason Thomale's
Code4Lib Journal article might be useful for providing some of that
background for Marc (although I don't neccesarily think his
explanation/analysis/solutions are airtight, they're an introduction).
