Library Merger
Keep your Libraries in sync
Free · Designed for iPad. Not verified for macOS.
Study with JW Library® on multiple devices, while still keeping your notes, markings, and bookmarks in sync.
You know the problem: You study with JW Library® on different devices - and in the end, you have two versions, that you can’t easily combine anymore. With the Library Merger this is a thing of the past!
The Library Merger allows you to quickly and easily combine two JW Library® backups into one. Simply open both backups in the app (you can even send them via AirDrop). The app will merge them into one. If it finds a conflict (like two bookmarks at the same place, or two markings that overlap), you can choose which version to keep. In the end, you have one merged backup which you can easily restore on your devices. The process - if done regularly - literally takes you seconds!
Library Merger is still in its early stages and is being actively developed. The code is open source and can be found on GitHub. If you found a bug or have suggestions, feel free to contact me.
This update adds support for backups created by the latest JW Library version.
Support for older backup version have been removed. If you need to merge an older backup, you can import it into JW Library first and export it again. This makes sure it is using the latest version.
