Set a deadline for completing the literature review -- then meet your deadline.
Use the required format from the time you begin writing.
Keep a working bibliography.
Remember, good writing informs the reader about what you are going to say, says it, then summarizes what you have said.
Attach a cover sheet to anything you print or copy -- put the bibliographic information on the cover sheet and include important information or notes about the general content, theories, findings, or instruments detailed in the item.
