Sure, I'd be happy to, I thought LoC was only used as a unit of measurement on Slashdot.
The LoC holds around 24M cataloged books [1] in its collections.
So the difference between a lead paint detection kit and this project is like the difference between the LoC and a single bookshelf of 72 books.
Or, if you prefer bigger numbers, the LoC has around 540 miles of shelf space [2], so if you laid out all the shelves end to end, it's like the difference between the shelves of the LoC versus shelves that span 180 million miles (greater than the distance between Mars and the Sun [3])
> 15 ppb

Is there some way you could put this in terms of libraries of congress? Maybe if we laid them end to end?
