No writer’s or editor’s desk is complete without a battered, page-bent copy of the AP Stylebook. However, this not-so-easy-to-use reference of journalistic style is often not up-to-date and leaves reporters and copyeditors unsatisfied. Bill Walsh, copy chief for the Washington Post’s business desk, addresses these shortcomings in Lapsing into a Comma. In an opinionated, humorous, and yes, curmudgeonly way, he shows how to apply the basic rules to unique, modern grammar issues. Walsh explains how to deal with perplexing situations such as trendy words, foreign terms, and web speak.
