Hold the rejoicing! No rejoicing until job offer!
Muted good wishes would be okay. 
w00t! Dopers offer good wishes!
IMHO, this is a good general rule for “just out of college” and during the infancy of a career … but after a certain point, multiple pages are fine.
If you ever cross this bridge – the federal government likes looooong resumes. But they want every single job you’ve ever held fully fleshed out – the summer fast food job you worked between junior and senior year of high school is to be treated in text as equivalent to a stint as CEO of a Fortune 500 company.
I often see resume advice that suggests one should bend over backwards to somehow express your accomplishments in numbers. But isn’t that hugely job-specific? In finance, in sales, in private business management … yeah, you can often get meaningful numbers that demonstrate you value in that field.
But a lot of people – a LOT of people – work in fields that are not profit-driven (e.g. civil service, government) … or work in positions that are far removed from any profit drivers (e.g. a typical receptionist at a car dealership can’t take credit or receive blame for the dealership’s sales figures). And a lot of people who hire in these fields understand that, and would look askance at hard numbers in a resume, because they’d almost certainly be numbers pulled out of thin air on one-size-fits-all advice.
Admittedly, the use of numbers you suggested have nothing to do with profitability or money. At the same time, I’d be concerned that there’s nobody out there making lists of “top 10 research branch libraries”. Even if there were, how can the OP take sole responsibility for that?
Objective: the same thing we do every day, Pinky, try to take over the world.
