Managing access to your list
If you have created a list on a SharePoint site, anyone who has access to the site will, by default, also have access to this list. When you add somebody new to the site, that person will also be able to work with the list. And correspondingly, when somebody's permissions on the site are removed, this person also loses access to the list.
However, there are often cases where you may want to share the list with a few more people, but not necessarily grant them access to the site itself. For example, you could have an IT Budget site where your various IT managers and other relevant staff have been granted access. Within the site, you also have a Planned IT Projects list, where you want to keep track of potential future projects and their estimated cost. There are people who are expected to provide details for such IT projects and add entries to this list, but they should not be allowed to see anything else within the site.
This is where sharing...
