FOUNDATIONS
Start With the Basics
Before diving into production, establish key foundations by making fundamental decisions about format, trim dimensions, and identification.
Choosing the Right Book Size
Trim size influences page count, spine width, production costs, and genre conventions. Choose the proportions that suit your reader's hands.
Paperback or Hardcover?
Understand the cost, shelf-appeal, and reader expectations between flexible perfect-bound trade paperbacks and case-bound hardcovers.
Understanding ISBNs
An ISBN uniquely identifies each edition of your title worldwide. Learn when to buy your own block versus using distributor-assigned numbers.
What Is an LCCN?
Library of Congress Control Numbers help libraries and catalogs index your book. Understand eligibility and pre-publication application windows.

DISTRIBUTION PATHWAYS
Amazon KDP or IngramSpark?
Choosing between direct retail placement and broad wholesale catalog distribution is one of the most critical logistical decisions for modern self-publishers.

Amazon KDP (Kindle Direct Publishing)
Amazon KDP provides seamless direct integration into the world's largest consumer book marketplace with fast turnaround and no upfront setup fees.
Best suited for:
- Direct access to Amazon's global reader marketplace.
- Frictionless paperback (POD) and Kindle distribution.
- Exclusive KDP Select program options for eBooks.
- Author Copies and Expanded Distribution network.
IngramSpark
IngramSpark feeds directly into the global Ingram Book Company catalog, allowing brick-and-mortar bookstores, universities, and public libraries to order your title.
Best suited for:
- Global distribution to thousands of retailers and libraries.
- Unified platform for jacketed and case-laminate hardcovers.
- Customizable wholesale discount rates and return policies.
- Industry-standard ordering channels outside Amazon.
Many professional self-publishers use both platforms strategically.

QUESTIONS & ANSWERS
Common Publishing Questions
Clear, technically accurate answers to recurring author concerns about identifiers, file specifications, and physical printing.
Does every book need an ISBN?
Every distinct edition offered for commercial sale (paperback, hardcover, audiobook, and sometimes eBook) requires its own unique ISBN to ensure accurate cataloging, ordering, and royalty tracking across retailers and libraries.
Do I need an ISBN for Amazon KDP?
Amazon can assign a free KDP ISBN for paperbacks, but Amazon will be listed as the publisher of record and the number cannot be used on IngramSpark or other printers. If you want full publisher ownership, provide your own ISBN.
Does an eBook need an ISBN?
Amazon assigns an ASIN and does not require an ISBN for Kindle eBooks. However, other distributors like Apple Books, Kobo, and library aggregators either require or strongly recommend an ISBN for consistent discovery.
What resolution should photographs be?
Images must be at least 300 PPI (pixels per inch) at their final printed dimensions and converted to CMYK or grayscale color space to reproduce cleanly without pixelation or muddy contrast.
Can I upload a Microsoft Word file directly?
While some platforms offer automatic Word conversion, doing so almost always produces font shifts, bad page breaks, unanchored images, and irregular margins. Commercial print demands a strictly validated PDF/X document.
Why does page count matter?
Page count directly dictates your spine width calculation, unit printing costs, minimum spine text thresholds, and whether the interior must conform to signatures (multiples of 4, 8, or 16 pages).
Should my book have bleed?
Standard text-only interiors do not require bleed. However, book covers and interior pages with photos, tinted background panels, or decorative elements running off the page edge must include 0.125" bleed on all outside edges.
What is a proof copy?
A physical sample copy produced on the actual print machinery prior to public release. It allows you to examine paper weight, color fidelity, spine centering, and reading rhythm before approving global distribution.
