There is a library folder in the home folder.
If the original Library folder was deleted (or misplaced) at the time of the restart, a new Library folder may have been created in its place.
Check to see if this library folder seems like it's yours...
For example, look in the 'Widgets' folder (in the library folder). If you had any widgets installed (besides those included with OS X) they would be in located here. If it is empty, this is not your library folder (unless you don't have any other widgets).
You can also check other folders such as 'Mail'; if this is the original it will have a folder in there named after your mail account name.
Also try 'Application Support' - look for a folder relating to any applications you may have installed (not included with OS X).
In general, just look for any signs that it's yours.
BTW: Make sure you are checking the library in your Home folder, and not the system library.
