I write occasional guest blog posts for a special interest blog with a very large readership. I don't get paid but that's okay, I have a strong interest in the special interest area, and it's very satisfying to share information in (cough) what I consider is a well written way.
My hope is that this exposure will help spread the word about my book when it is finished.
I haven't decided yet whether to submit to a publisher or self-publish. If one submits to a publisher, what does one do about the fact that some of the material has already been published (in the blog)?
The posts on this particular blog stick around for years, and continue to attract readers. I know because comments continue to appear in a slow steady stream.
I am thinking about making my own website, also, in which to re-publish (with permission, of course) the same posts, along with some additional material, most of which would be related to the book. (For example, some appendices with related technical information that would not fit into the book, or that would be too tedious for the book, but which some readers would devour, as they are trying to figure some things out.)
Is it still possible to submit to a publisher in these circumstances?
