Self-Publishing Glossary

Clear explanations of the terms you'll encounter on your publishing journey. No jargon, no fluff — just what you need to know.

Print on Demand (POD)

Books printed one at a time, only when ordered. No inventory, no upfront costs, no garage full of boxes. The technology that made self-publishing viable for everyone.

ISBN

The 13-digit number that identifies your book globally. Required for print distribution, optional for ebooks. Books.by includes free ISBNs — elsewhere they cost $125+ each.

KDP Select

Amazon's exclusive program that locks your ebook to Kindle for 90 days. You get Kindle Unlimited access and promotional tools — but can't sell anywhere else. A trade-off worth understanding.

Wide Distribution

Selling across multiple platforms instead of being exclusive to one. More reach, more retailers, more resilience. The opposite of putting all your eggs in Amazon's basket.

Learn more

Book Distributor

Companies that get your book into bookstores, libraries, and retailers. IngramSpark is the big name. Essential for physical bookstore placement, less relevant for direct-to-reader sales.

Learn more

Trim Sizes

The finished dimensions of your printed book. 6×9 for most fiction, 5.5×8.5 for literary, 8.5×11 for workbooks. Your choice affects printing cost, shelf presence, and reader perception.
