Google Docs uses a concept called "collections" to easily share a variety of files with the same person or group. To create a collection, first select collection from the Create new drop-down menu.
Enter a name for your collection and click Ok.
To add items to your shared collections, drag each doc from your Documents List to the collection. Sharing a collection with someone isthe fastest way to give someone access to the items on your collection. Just click My collections in the navigation pane on the left of your document list, select the collection you'd like to share, click Share from the drop-down menu, and select Sharing settings....
At the bottom of the 'Sharing settings' window, under 'Add people,' enter the email addresses of the people with whom you need to share the collection.
Note: When you share a collection, the new permissions are pushed to all collections and documents within the main collection.
Collections others share with you will appear in the main pane of your Documents List. Only collections shared directly to your email will appear here. If a collection was shared with you through a mailing list, you will need to click the link in the email first.
