I have backed up my Hard drive using Time Machine including my Aperture Library however I can not open the library on the external drive as a dialog pops up informing me that I don't ave any permissions. Aperture then closes. Read write permissions for the library seem to be fine
iMac, OS X Mountain Lion, iMac 27 8Gb RAM 1Tb Hard Drive
Is the external drive you are trying to access the Time Machine backup drive? If so what you are seeing is correct. You cannot open the library until you have restored it out of TM.
If this is not the situation post back giving more detail.
Yes I backup the iMac's hard drive using Time Machine.
That's sort of an odd reply. We know you use TM you stated that in your first post.
The question is is the Aperture library you are trying to open on the TM drive.
If it is then what you are seeing is correct and you need to restore the library out of TM before you can open it.
This is new to me, but how does one restore the library out of TM, sorry to be so thick. What Im trying to do is to free up hard drive space on my iMac. I have over 500GB of photos in one library. Once I have backed up the files I would like to delete the Library on the iMac and then proceed create a new library.
What is the best procedure to do this.

Don't use Time Machine to copy a Library.
Just copy your Library (it's a file; copy files using the Finder) to any locally-mounted (i.e.: not networked) drive, then double-click the Library name in a Finder window. This will opened the copied Library (perforce from its location on the external drive) and let the OS and Aperture know that it is the Library you wish to use. Confirm that it is complete and works correctly, then delete the "old" Library on your system drive. Note that you should include the external drive in your back-up practice.
The external drive must be formatted Mac OS Extended (Journaled). Format drives using the OS X bulit-in program Disk Utility.
Post back if you still get permissions denials.
As always, _never_ use any computer file without having a back-up available.
I have now created two Vaults on the external hard rive one for the Library with over 500Gb of images, and a new vault for my current work.I don't intend to add any more images to the 500gb Library. Now that I have a 500Mb Vault on my external drive; can I now proceed to delete this library on the iMac?
