I have created a library in Eagle 7.5.0, then I copied it in the folder where Eagle keeps its libraries but and I can't use it. When I try to add new component the library is not among the available ones. When I am in Eagle I can open it and modify it but I can't use it in a schematic. What am I doing wrong?
The custom library is Components

This isn't a direct answer, but you really shouldn't put your own libraries into the directory where the Eagle libraries are. You don't know what will go there in future releases that might overwrite your files.
Create a directory for your own libraries. Then add it to the library search path.
I go further and deleted the Eagle libraries directory from the libraries search path, since the Eagle libraries are of little use and it's easier to make your own parts than vetting their, even when theirs are acceptable.
As for why you library isn't showing up, I don't know. I do what I described above and all my libraries show up all the time.
