I coordinate the Book Editing Associates freelance network.
Book-Editing.com is a service for writers that:
...screens, tests, and monitors book editors, proofreaders, indexers, and publishing consultants;
...allows you to locate and have direct contact with highly experienced book editing, proofreading, book indexing, and publishing professionals through one site; and
...helps writers avoid self-appointed but untested "copy editors," "proofreaders," and other online pitfalls and scams that target writers.
