Don LePan (born 1954 in Washington, DC) is widely known as a book publisher; he is the founder and president of the academic publishing house Broadview Press. He is also a painter and the author or editor of several books, most notably the dystopian novel Animals.

The Broadview Book of Common Errors in English offers full coverage of such common mistakes as commas splices, sentence fragments, words frequently confused, words frequently misspelled, mixed metaphors, and subject-verb agreement errors. In each case the problem is clearly explained, with examples illustrating both the nature of the trouble and how to put it right. Unlike many guides to grammar and usage, The Broadview Book refrains from dogmatism; it treats correctness in English not as an unchanging objective standard laden with moral overtones, but rather as a code of convenience that is extraordinarily useful in helping humans to communicate effectively and even elegantly. It thus retains an openness to the inevitable process of change in the English language, and recognizes that change does not imply debasement. The fifth edition has been updated throughout, and includes new material on capitalization; on the connections between clear writing and clear arguments; on academic citation systems; on business writing; and on particular difficulties experienced by those whose first language is not English.
