Google Docs now let you share a group of items, just put them all into a folder and share the folder. If you add an item to a shared folder, it’ll automatically be shared and if you add someone to an existing shared folder, they’ll instantly get access to all of the folder's content."When you share a folder, the new permissions are pushed to all sub-folders and docs within the folder. Normally this happens quickly, but occasionally, it could take a couple of minutes," explains Google. Also using new upload page, you can upload multiple items to Google Docs. First click on "Select files to upload" and use "Shift" or "Ctrl" to pick multiple files. Then press "Start upload", and see it on progress bar.
