Glossary

The words of lead magnets, email lists and ebook publishing, each defined in one sentence.

  1. AI-assisted vs AI-generated: what is the difference? On KDP, AI-generated content is created by an AI tool, even if edited later. AI-assisted content is created by you and improved with AI. Only the first must be declared.
  2. What are widows and orphans in typesetting? A widow is a paragraph's last line stranded at the top of a page. An orphan is its first line left at the bottom. How to fix them, and how Chapbook's PDFs handle them.
  3. What is a BISAC code? BISAC subject codes are the US book trade's standard topic categories. What a code looks like, how many to use, and how they relate to KDP's own categories.
  4. What is a book spine? The spine is the bound edge of a book, the part you see on a shelf. How KDP's paper and page count set its width, and when it can carry text.
  5. What is a fixed-layout ebook? A fixed-layout ebook keeps every page exactly as designed instead of reflowing. What it gives up, when it is worth it, and what Chapbook does instead.
  6. What is a lead magnet funnel? A lead magnet funnel is the path from a free offer to a subscriber to a customer. The steps it takes, and which of them Chapbook handles and which your email tool does.
  7. What is a lead magnet? A lead magnet is something useful given away free in exchange for an email address. What makes one work, the usual formats, and how it differs from an ebook.
  8. What is a merge field in email? A merge field is a placeholder in an email that your tool replaces with each subscriber's details, such as a first name. How to use one, and what Chapbook passes on.
  9. What is a reflowable ebook? A reflowable ebook has no fixed pages: its text rearranges to fit the screen and the reader's type size. What that changes, and why Chapbook's EPUB works this way.
  10. What is a running head in a book? A running head is the line at the top of a book's pages naming the book or chapter. Where it goes, where it doesn't, and how Chapbook sets one in a real sample.
  11. What is a welcome sequence? A welcome sequence is a short series of automatic emails a new subscriber gets after signing up. What each email does, and the one Chapbook writes from your book.
  12. What is an ASIN on Amazon? An ASIN, Amazon Standard Identification Number, is the identifier Amazon gives each book it lists. How it differs from an ISBN, and what you do with one.
  13. What is an EPUB? EPUB is the open file format for reflowable ebooks. What is inside one, how it differs from a PDF, and what Chapbook's EPUB 3 export includes.
  14. What is an ISBN? An ISBN is a 13-digit identifier for one format of a book. Who applies for one, when KDP gives one free, and where Chapbook puts yours if you have one.
  15. What is back matter in a book? Back matter is what follows a book's main text: an appendix, notes, an author bio or a call to action. What it is for, and what Chapbook adds at the end of a book.
  16. What is bleed in book printing? Bleed is artwork that runs past the cut line, so it reaches the page edge after trimming. KDP's bleed size, the page it makes, and when Chapbook adds it.
  17. What is double opt-in? Double opt-in means a new subscriber confirms their address from an email before joining a list. Why lists use it, and how it works with Chapbook's sign-ups.
  18. What is front matter in a book? Front matter is the pages before a book's main text: title page, copyright, contents, and sometimes a foreword. What Chapbook adds on its own, kind by kind.
  19. What is KENP on Amazon KDP? KENP, Kindle Edition Normalized Pages, is how KDP counts pages read in Kindle+. How it is measured, its per-customer cap, and how it differs from a sale.
  20. What is Kindle Direct Publishing (KDP)? Kindle Direct Publishing is Amazon's free self-publishing service for eBooks, paperbacks and hardcovers. What it asks for, and what Chapbook prepares for it.
  21. What is list hygiene in email marketing? List hygiene means keeping an email list to addresses that work and people who still want your email. What to remove, why Gmail cares, and what stays in your tool.
  22. What is opt-in? Opt-in means a person actively agrees to receive your email before joining your list. What counts as agreeing, and how Chapbook's sign-up form records it.
  23. What is print-on-demand? Print-on-demand means a book is printed only after someone orders it, with no stock to buy or store. How KDP's version charges for it, and where Chapbook fits.
  24. What is the gutter in a book? The gutter is the inside margin of a printed page, the part closest to the binding. KDP's minimum by page count, and how Chapbook's paperback follows it.
  25. What is trim size? Trim size is a printed book's final width and height, after the pages are cut. The sizes KDP offers, what they change, and the ones Chapbook's paperback uses.
