Link from one Google Doc to Another Google Doc
Ever wanted to link from one of your Google documents to another? You can! Go to a Google doc you want to link TO. Click on share. You can still make it shared only with you, or whatever is appropriate. Grab the link available in the share area. Go to the document you want to link FROM. Highlight some text in that document and click the add a link button. Paste in the url you grabbed from the share area and voila!
