The other half of the job
In response to an e-mail asking about how he markets his books, [Seth] Godin wrote: "The unspoken truth is that except for perhaps 250 giant books every year [out of 75,000 published], the publisher is expecting the author to do 100 percent of the sales and promotion. Because authors don't understand that, they end up bitter, angry and perhaps destitute."
And later . . .
His advice to authors is to get out and really work for their books: "You need a platform to make a published book work. If you don't have a platform yet, you should self-publish your first book and give away enough copies to get a platform, and then use that platform to engage your readers so that you can sell the second one to a publisher and quit your day job.''
