Ex Libris
From Tardis Wiki, the free Doctor Who reference
Ex Libris was an old, hidden archive underneath a London library, visited often by Yvonne Hartman to gain intelligence regarding alien activities or species. The archive was run by Mehdi.
In late 2005, Hartman met with Mehdi to discuss Planet XXX and its dominant species. When she unexpectedly came under attack from Kieran Frost, she had to take the paperwork and flee. (AUDIO: Through the Ruins)
