Like many writers, I read Strunk and White’s Elements of Style several times (it’s a short book). Nowadays, books on writing have more imaginative titles like Sin and Syntax, Eats Shoots and Leaves, and The Transitive Vampire.
The current books with their creative themes are good because they generate interest in writing readable English. But, we should not ignore older books on writing, even with their plain titles. Things haven’t changed that much.
I recently read A Handbook of Short Story Writing by John T. Frederick, published in 1924, and If You Want to Write by Brenda Ueland, published in 1938 (recently reprinted).
Both had basic writing advice that is just as good as the current books. One advice I found useful: a writer should always write to someone.
It may be a stuffed toy, an imaginary friend, God, or someone the writer knows. It could be a small audience of people, a bigger group in a specific genre, or the writer through a diary. When writing, there is the intent of a reader.
Back to books about writing.
People who write text messages, emails, notes, or shopping lists do not need to read books about writing. Those who want to communicate by writing, should.
Whether it has an imaginative title or was written a hundred years ago, writing readable English means writing so a person could be understood clearly. Whether a writer is writing to someone, no one, or to themselves, there is the hope of a reader.
