Option 1: Complete Upgrade
Build on Your Current Library and Features
A complete upgrade adds new Logos features and an entire library of new books to your current Logos package. These books don’t replace your current library—they add to it. The same goes for features, and it’s true no matter which package you choose. When you upgrade your Logos, you don’t lose anything you owned in a previous version of Logos.
Only Pay for What’s New to You
If you already own some of the books included in the upgrade you have your eye on, we subtract the value of what you own. That way you don’t pay for the same books twice. Learn more
