For researchers and writers in biotechnology, the National Center for Biotechnology Information (NCBI) has created this comprehensive and easy-to-use style guide that may help. The digital publication is divided into two parts: tips for general writing and tips for the biotechnology field. Part I includes guidelines for grammar, punctuation, and style that will be helpful to writers in any field. In fact, writing instructors may want to point students towards this section, which includes notes on "Wordy Constructions to Avoid" and "Voice: Active versus Passive." Part II outlines disciplinary conventions in biotechnology with special attention to writing for web pages. [MMB]
