I found this cool site, One Day, One Job, that profiles a different job/company every day. Over the weekend they featured Heldref Publications, a nonprofit book publisher in Washington, D.C. The profile tells about the history and workings of the company, mentions a job opening for a proofreader, and tells you how to apply directly to a real person there.
I've put One Day, One Job on my feeds to see what other jobs and companies will come up (although they are not always publishing jobs). I also advise you to look through the list of past posts for more company profiles, including Random House, Amazon.com, and Better World Books.
And this week they announced a new sister site called One Day, One Internship, which does the same thing with a different internship each day.
