Along with the AP Style Guide, I keep this book by my desk at all times. Between the two of them, I can find the answer to just about any question I have on grammar. While searching the Internet may offer some results as well, none are as trusted and reliable as these two books.
The Elements of Style was actually the college textbook in Strunk's English class, and was later revised and expanded upon by E.B White, who first read the book while taking Strunk's class. It is so incredibly concise, factual and to the point that it puts us wordy creative writers to shame.
With only 95 pages, including the glossary, The Elements of Style says it all without being verbose. You can learn exactly how to handle commas, compound sentences and any other common English question, along with excellent examples to guide you through each section.
Comprised of just five major areas, Elements talks about such topics as usage, composition, form, misused words and expressions and style.
If you can choose only two books to guide you through your writing career, let The Elements of Style be one of them. Your readers and your career will benefit from the valuable insights contained within.
