Abstract:

Style guides describe conventions for virtually every aspect of writing, ranging from such things as spelling, punctuation, and word usage, to structural and formatting issues. With the myriad of style guides in use, the dilemma for many writers is deciding which one to learn and apply in the trade. The answer to this is easy: learn at least one style guide thoroughly and keep a selected few others for backup. In the course of recruiting technical and generalist writers and editors for nearly a decade, I am sometimes shocked at the low level of familiarity with long-established style guides by people who claim to be seasoned professionals in this business. The reality is that it is plainly obvious to spot writers who “claim” to know a style guide and those who have actually taken the time to study it. The proof is in the pudding, as they say. The quality and consistency of a writer’s or editor’s output is the litmus test to how proficient he or she is in applying a given style guide.
