customizing SharePoint libraries

[TopDog]

What are some ways you can customize a SharePoint library? Is there any one kind of customization that you'd strongly recommened SharePoint users do?

You can customize libraries in several ways. You can control how documents are viewed, tracked, managed, and created. You can track versions, including how many and which type of versions, and you can limit who can see documents before they are approved. You can use workflows to collaborate on documents in libraries. You can specify information management policies to manage the handling and expiration of documents within libraries.
