Fix the date issue when searching books.
Currently, if you search for books within a time frame, e.g. last five years, you will also get books that were published outside the date range, e.g. 1980. This is a serious problem for students needing to be current, yet having to sift through older material to find newer material. This is not an issue with journal articles.
