An author bio is a brief passage, usually about a paragraph, that introduces an author and sums up their work, their authorly credentials, and anything else their readers might need to know about them. While author bios may seem like an afterthought, or something to fill up the backmatter of your book, it’s actually an unassuming but valuable piece of copy. Done well, an author bio can give you credibility and introduce your readers to your other works. It can also be used in other promotional or publishing materials, as former Penguin Random House marketer Rachel Cone-Gorham explains: Address:- 112 Commerce Boulevard La Vista, NE 68128 Con.
