By all means. From time to time EFA holds joint programs with other associations, which often gives people the chance to explore other career opportunities in the freelance world. In fact, many freelancers try to steer clear of the publishing industry because it's notorious for paying poorly. In truth, it's unfair to portray all publishing houses as tightfisted. But many are, and even the more generous ones usually don't have large budgets for their editorial needs.
Editors do it all.
Their primary job is to take the words and turn them into a final product, but editors also manage projects and hire the writers and other contractors. These editors develop a book or other project from the initial concept onward. They work closely with the author or client to study competing works and create a product that stands out. Also called project managers, project editors see a project through from start to finish. They supervise and coordinate the editorial process and when necessary hire copy editors, proofreaders, indexers, and other editorial workers.
