It doesn't seem there are limits to the number of libraries in a site collection, just more of a global size allocation @ the site collection / DB level.
Please advise if we do have any library count limit per site collection.
Thank you!
in theory:
Maximum no of items including list item and document in a content database is 60 Million
Maximum no of items a list can have is 30,000,000 per library i.e 30 million, so roughly you can have 2 million list in a site collection each list having 30,000,000 items
from support perspective so you can 2 million list in one site in a site collection or divided it into the number of sites you plan to have in you site collection accordinly.
in practice:
Seem 2000 lists is the suggested limit.
Note that the limit isn't an "hard limit" but performance seem to degrade exponentially after that point.
