Document/item access

- Here I am inside the Expense Reports document library…which is in the Expense Reports site…which is the top level side of a site collection…which was based on the team site template.…I've uploaded several Expense Reports now…and I had set approval required…and I have gone ahead and approved several of those.…I've also added a folder and inside of that folder,…I've added a couple of Expense Reports as well.…So here's my Expense Reports library,…here are the documents in that library,…here is a folder in that document library.…

I can access this because going back to the mall map,…this is the top level side of a site collection.…The site collection was given the out of the box…Sharepoint security groups with the out of the box…permission levels assigned to them,…based on the top level site template.…This is a library within that site.…So unless I change something, unless I stop inheriting…the permissions, if I wanna access something…in this library, I have to to have been given access…to something via the site.…
