How to Merge Eagle Library Files Downloaded From SnapEDA Into a Single Library

I am often asked how to merge individual Eagle library files downloaded from SnapEDA into existing libraries, or into one big library. Although this is available as a feature included in SnapEDA’s Premium version (ie. the ability to batch together parts and bulk download them into a single Eagle library file), there are also several other ways to do this manually. Here’s one of the easiest ways I’ve found:

1. After downloading an Eagle .lbr file from SnapEDA, move that file into the lbr folder within Eagle’s application directory
2. If you have an existing library you’d like to add that .lbr file to, open that library by going to File > Open. Otherwise, create a new library file  and Save the library with the desired name.
3. Open the Control Panel by going to Window > Control Panel
4. Expand the Libraries item
5. Find the .lbr file downloaded from SnapEDA, then expand it. At this point you should see device, package, and symbol items
6. Right-click on the device, and select Copy to Library (note: if this option is greyed out, you need to double-check to make sure the library you are trying to copy to is open)
7. Repeat this process for every .lbr file you would like to add to the library

With the Premium version of SnapEDA, parts are consolidated into a single library upon downloading your Private Parts Library. For more information, or to join our Beta, email info@snapeda.com.
