Connecting People to
Good Books
Share and discover good books with your church, school, or community. Set up your shared library in 10 minutes.
What is Agathos Books?
Agathos Books is a Christian book-sharing platform for churches, schools, families, and communities. Unlike traditional library tools, members add their own books to the shared catalog, so a 100-book collection can grow into 1,000 as people contribute what's on their shelves. Reading becomes social, too—see what your community is reading, and discover recommended books from trusted sources. Scan a barcode to add a book, and lending, reminders, and returns are handled for you.

Their books stay put until someone requests one, so everyone benefits from each other's collections.

Why Agathos Books?
"Agathos" — the Greek word meaning "good"
We believe good books change lives. That's why we built Agathos Books: to make it easy to share and discover them within your own trusted communities.
My Christian testimony cannot be told without speaking of the major impact that good books have had in my life—books that are faithful to Scripture and helpfully communicate its principles, meaning, and practical application.
I did not have strong mentors growing up, but God graciously connected me with many good books that helped grow and mature me. Faithful authors became teachers, pointing me again and again to Christ and His word.
— Greg Leininger, Creator of Agathos Books

What Makes a Book "Good"?
Books that point people to the truth found in God's word
Fidelity to Scripture
Does not promote sin or contradict core biblical doctrine. They align with God's word and are not contrary to God's design and purpose.
Pure
Content that is edifying. Does not promote, glorify, or normalize sin. Protects communities from content that would lead readers away from the way of life presented in God's word.
True
Reflects reality honestly. A business book teaching integrity reflects God's design. Classic literature exploring the human condition can illuminate our need for redemption.
Beneficial
Equips readers with wisdom for godly living. Books that shape minds, change hearts, and build communities—whether through theology, fiction, history, or practical skills.
Good Books Across Many Genres
What makes a book "good" is not merely its genre, but its alignment with truth and purity.
Christian & Theology
Resources that deepen understanding of God's word, equipping believers for faithful living and pointing directly to Christ.
Fiction & Literature
Stories that explore truth, beauty, and the human experience without glorifying sin—from classics to contemporary works.
Practical Resources
Business, health, education, family, and biography—books that equip us with wisdom to live well and serve others.
An Intentionally Curated Platform
Agathos Books has a book approval process—by design. This is not a general book platform. We want to protect our communities from destructive content and curate excellent books that edify and strengthen faith.
We hold to the truths in the Bible precisely because we love people as God loves people—pointing them to truth, protecting from error.
