From Digital Book World:
The front matter of a book communicates a lot of helpful and important information to readers. But publishers and authors often find themselves wondering how to handle that information in their ebook files. In the current installments of my column here on Digital Book World, I am delving into some best practices, ideas and options for these opening and ending parts of your ebook. In my last installment, we started talking about the copyright page. We will continue that discussion below.
. . . .
Some books, especially older ones, have a colophon page that includes basic information about the publisher, including a logo, location and other details. This page is often combined with the copyright page in current publishing approaches, so you probably have that information on your copyright page.
The colophon also sometimes includes information about the paper and fonts used in creating the print book. If you have that information in your ebook, be sure it matches the actual details of the ebook itself. For example, saying “Printed on acid-free paper” is not really appropriate. You can change that to “The print edition of this book is printed on acid-free paper” or something similar, or you can just remove it.
Fonts are a common concern in ebooks, and many publishers do not use the same fonts in their ebook files as they do in their print books due to licensing difficulties and support across devices. If your copyright page includes information about the fonts used in the print book, be sure that still applies to the ebook you are creating.
. . . .
The CIP section of the copyright page contains information generated by the Library of Congress about your book. According to the Library of Congress’s website, “The CIP Program limits eligibility to titles that are most likely to be widely acquired by the nation’s libraries.
. . . .
It is also important to note that the CIP program is not available to “books paid for or subsidized by individual authors.” So if you are a self-published author who would like to register with the Library of Congress and get a CIP section, you will probably need to set up a publishing company first.
. . . .
Version numbers are common in software publishing, but less so in ebooks right now. That is changing, however, and you can benefit greatly from using them. A version number is not that hard to decipher. Take, for example, this one:
If you were going to create a version number for your ebook, you would start out at “1.0.0” (or just “1”). If you need to come back and make a small change to the file, such as to fix a typo, you would increment the last number in the chain, making the new version number “1.0.1”. If you later found out that you needed to change a lot of things in the ebook at once you might update the version number to “1.1.0” to show that a lot of changes were made. If you decided to do a major re-write or make other major changes to the book, then you might change the version number to “2.0.0”.
