To find my art, I've got a number of portfolios out there online. Let me know what you think.
Well, from a practical point of view, what do you base your cover dimensions on? It's hard for me to estimate since you have the spine on there as well - THIS
seems to have most
of the industry standard sizes.
I've chosen to format all my pdf paperbacks (as I call them) as, well, standard sized "A" format Mass Market Paperbacks, which are 110mm x 178mm (4.33" x 7.01"). This is so that a double-page spread, viewed at 100% fits on most computer screens. It makes it so that in theory
the pdf file could be handed to a Print On Demand printer and a copy could be run off and glue bound - all that would be needed would be a spine and back-cover. Why don't I include them? For the same reason why I don't include the bar code, the fly-leaf, Inside Front Flap, Pastedown / Endpapers or Endsheet - they are redundant in an electronic book. The purpose of a printed spine exists so that you can know the title and author of a book when stacked on a shelf. A back cover is there because the prospective buyer can read a little about the book without opening it – the all-important promotional text. In a pdf paperback, the back page is really
at the back of the book, only accessable by opening the pdf and fast-forwarding through all the pages – NOT the place you will place things to catch a prospective reader's eye! Certainly we still need all this material, the title, author, promotional blurb... we just need to find somewhere else for it. I put it all at the front of the book (and in my advance promtion) but ymmv.
These are all editorial decisions that the publisher makes, and each will vary. Steph Watson, for example, formatted her edition of "Arc of The Wolf"
entirely differently! The whole production exuded class from every seam! The cover, the front-matter text placement, the proportion of white-space to text - it is like a high-quality hardback sitting in your screen.
