Are you an avid reader?  If you are and have not discovered goodreads.com, you may want to check it out.  On goodreads you can keep track of all of the books you have read and would like to read.  You can get reading ideas based on the books you have read and discuss books with other readers.  There are literally thousands of reading groups you can join, depending on your interest.   If you like trivia, there are quizzes on hundreds of books, including a never-ending book quiz.   I have kept a list for over ten years of books I have read, and on goodreads I could enter them and then tag them under different categories, such as historical fiction, nonfiction, suspense, favorites, etc.  It’s a great way to recommend books to people, depending on their reading preference.  So, if you’re a reader I encourage you to give goodreads a try.
