This link will take you to e-books that the OWHL owns. Your assignment affords limited time to conduct research. If you do find a book here that is helpful, be sure to look at the table of contents and/or the index, which will help you narrow down the section of the book you may need. Also, you should use your skimming skills to find paragraphs or sections within a chapter that may be helpful. It would likely be best to search here after you have looked at databases.
