Without exception, the most thorough resource list for writing and editing I know of is HERE at my editors network, The Christian PEN (Proofreaders and Editors Network). Whether you need a good dictionary, grammar guide, or specific resource for editing newsletters, this is the place to start!
If you are looking for resources for writing, here are the books I recommend most often to my editing clients:
James Scott Bell: Plot and Structure and The Art of War for Writers
Donald Maass: The Fire in Fiction
Nancy Lamb: Writer’s Guide to Crafting Stories for Children
And I also highly recommend a subscription to Writer’s Digest.
