If you happen to have skills in a language other than English, Wiley Publishing may be looking for you. I received the following through the grapevine:
"We are looking for proofreaders and indexers who are fluent enough in a foreign language to proofread and index. We're particularly in need of proofreaders who can proofread and index in Spanish."
This is a great way to get experience for your resume. If you're qualified, contact Rob Springer, proofreading manager, at firstname.lastname@example.org.
