I just followed his instructions and found the "show library folder" is already checked, but it still doesn't show in my "Go" dropdown list.
I deleted it because Urquhart's method is easier.
If you don't see
this, is there any change if you click on option?
This is from
18 ways to view the ~/Library folder in Lion and Mountain Lion | Macworld, and it's obviously old, but you can try...
Change the hidden flag using Terminal: Launch Terminal from within your own account, type chflags nohidden ~/Library, and press Return. Your Library folder is now permanently visible. To make the folder invisible again, use the command chflags hidden ~/Library.
