Answers.Body: <p>According to <strong>WorldCat.org</strong>, Tigran Petrosian's PhD thesis is available in three libraries: the Koninklijke Bibliotheek ("royal library") in The Hague (Netherlands), the Danish Union Catalogue and Danish National Bibliography (a catalogue strangely identified as a "library"?) and the State and University Library in Denmark. </p>
  
  <p>Apparently, the English translation is (or was) only available in 250 copies, so there may be other libraries that have it but that aren't covered by WorldCat.org.
