*"The
British Library is known to hold over 150 million items."
I don't think we want an article on every single arrowhead, pottery
fragment or piece of flint.
Those are now held by the British museum. 150 million is books and
book like items (pamphlets and maps for example)
*"the Internet Movie Database claims to
have records on 549,131 titles
and 2,280,301 names."
We definitely want that level of depth I think. Particularly since we
can at least cite the IMDB for all of them...
