What and where is the 'library' ?
The library is a folder in your userDir folder (normally ~/.node-red/) But in fact comprises of several different things that can show up. Including /examples/ folders from installed custom nodes - you'll see those if you look at imports rather than exports.
The local library is useful if you want to save snippets of flows or pre-configured nodes that you can then import elsewhere in your flows.
So to remove something from the library, what should I do?
in a terminal go to the .node-red/lib/flows folder and you should see the file. You can delete it or move it to another location.
