                                                          The term blue book actually comes from Kelly Blue Book, which is a yearly published physical book.  However, rather than getting this book, they have a website at www(dot)kbb(dot)com.  Go there and enter your car's make, model, and year to get its blue book value.  You can also check depreciation by factors such as distance.
