- KiCad library management can be difficult, but here are some tips and tricks to improve your libraries, and help improve your version control. In this episode of Professional KiCad, I go over how to create a local library, how to pull schematic symbols from the default KiCad libraries, how to create new parts, and some fields that you should always use to have as much information as you can on your BIll of Material.

Hey everyone! In this episode of Professional KiCad I go over how I setup and maintain my libraries for portability and version control. Be sure to let me know what you think and what other features of KiCad you might want me to go over in the future. And if you have any projects you'd like to see me attempt, drop a comment below!
very useful. thx!
Fantastic video. Thank you so much, helped me out a tonne.
Would be great to see a similar video about footprint libraries.
Thanks David! I have been hoping to get back to making video, it has been a while, but I have been overwhelmed with finishing school. I have definitely been planning on covering every step of the process to creating PCBs in KiCad, and I think footprints are one of the most important parts of your design, because it is the physical representation of your part! I have run into many issues in the past because of poor footprint design. Thanks for the comment!
Could use a video on how to use Git in this context.
The biggest hurdle I have found you have to overcome, is merging and making sure your workflow works correctly for you. I personally use local libraries and that allows the projects to be portable. I do pull from global libraries, like the KiCad libraries, and others I have built along the way, but I don't push to them very often. I pull from them to do what I need, and if it's a library I maintain, then I will push back after I have proven out the part.
there is no file/New library..one gotta go in the library browser and use the context menu
I am not sure where you are seeing this, but if you got to File->New Library in the Symbol editor, you can find where you can create new libraries. At least that is where it is in version 5.1.9, and I am pretty sure it has been that way for a while.
why not global ? you might need your component with other projetcs
I specifically don't use globals because of my workflow. I store my project on a Git repository, and having them all contained in a local file that goes with the rest of the project files is very helpful. You don't have to worry about including a global library to access all of your symbols on another computer if you work from several. I frequently do designs on my main workstation and my laptop, so I have to have that flexibility to jump between the two. There are benefits to both, but I prefer to use a local library. I can add part numbers specific to those symbols if I need to to create the Bill of Materials, I can add spice models, I can add 3D models to the footprints, and I can link the footprints to the symbols in the way that I intend. You can store them in both a global and local library, if you wish, but I find that causes more problems than it is worth. My projects are always self contained, portable, and clean. They don't contain more components than I actually use in the project. It is very easy to copy symbols and footprints between libraries, and knowing how to import symbols and footprints is also an important skill. One other benefit to keeping the parts local to the project is that if I have to make a change to a part for that project only, I don't have to remember to fix it later, and if you don't that can also cause you problems.
