Write from Home has a great (and free!) mini ecourse entitled "Writing for Profit: Break Into Magazines," by Cheryl Wright.
It has a good bit of useful information that can also be applied to other print medium, like newspapers.
Seeing this mini ecourse gives me an idea of what to do with a piece I've written on how to get a job in the print market. And one of the free ebooks I've posted about recently describes how to set up an ebook!
