Evolved from a Northwestern University editing course taught by Ryan and O′Donnell for more than 10 years, Editor′s Toolbox is designed as both a reference and a textbook. It will guide students and practitioners in the five essential language skills for editors (spelling, grammar, punctuation, usage, and AP style); detailed strategies for editing copy and writing headlines; and essential topics for the beginning editor (editing quotations, layout guidelines, photo editing, caption writing, and more).
