The books speak for their authors

Every book on ZI² Books is published by an independent Imprint. Its arguments, opinions, and claims belong to its author and publisher. Listing a book is not an endorsement of its views by the Platform, and the Platform does not check every statement in every book.

Not professional advice

Books here may discuss science, history, theology, health, law, or money. Reading them is not a substitute for advice from a qualified professional about your own situation.

Prices from other stores

Some book pages show a "market" price for print editions sold elsewhere, such as Amazon. That figure is collected at the time shown, is for information only, and may have changed by the time you look. The other store's price at checkout is the one that counts. Where a link to another store carries a referral tag, the Platform may earn a small commission from a qualifying purchase, at no cost to you.

Some Amazon links on this service carry the Platform's Associates tag. As an Amazon Associate, ZI² Books earns from qualifying purchases. That commission is paid by Amazon, never added to the price you pay, and does not influence which books are listed.

Links to other sites

Links that leave e.zi2.app go to sites the Platform does not control. Their content, prices, and privacy practices are their own.

Reading tools

Read-aloud, text sizing, search, and the other reading tools are offered to help, and are improved over time, but they may not suit every book or device perfectly. If something stops you from reading a book you bought, write to [email protected].

The .zi2 format

The published description of the .zi2 file format is provided so that anyone can build a reader for books they own. It is offered as it stands, without warranty.
