Excerpts from the Preface: "Words and Where to Put Them" was first prepared as a series of notes on problems of writing faced by economists in the Economic Research Service. They were written between September 1970 and May 1973 and circulated mainly in the Farm Production Economics Division. The purpose was to help improve writing by noting common errors and learning how to avoid them. The separate notes are now brought together to form a more convenient working handbook. The order of appearance follows the original chronology. An index provides a way of finding particular headings. The notes are just about as they were first written, except for omitting repetitive headings.
