Food and Drinks are stamped with expiration dates. What about books?
There are many novels, such as Tale of Two Cities, Jane Eyre, and countless others that remain classics with the passage of time. Those are not the norm. Except for historical novels, readers expect books to reflect the time period in which they're released.
Because of that, you may want to think twice about including current fads, happenings or buzzwords in your manuscript. Remember, a book usually gets released a year or so after it's accepted by a publisher. Will those cute phrases be popular then? Worse yet, will they be overworn and redundant?
What about places? When you include actual places in manuscripts you run the risk they may not be there when your book gets out, such as Marshall Field's. When I wrote my Chicago area mystery, Two Wrongs, little did I know that Field's, a Chicago institution, would be taken over by Macy's and the name changed. Fortunately, in the case of Two Wrongs, although Field's no longer retains its name, many people have fond memories of it. Some buy the book to relive the days when Field's was popular. That doesn't happen in every case, so be careful of the places you include in your manuscript, or make up your own.
References to a VHS player or dial phone, without a good explanation, would date a manuscript.
Can you think of instances where authors have included outdated fads, items, events, buzzwords, or places that are no longer in existence? Or, can you think of examples that should not be included because they may soon become outdated? What is safe to use? Please share.
