Gibraltar-Vatican Joint Issue
The Vatican City State issued its first stamps in 1929, the same year that it was established under the Lateran Treaties. It released its first joint issue in 1969. Joint issues of stamps by the Vatican and other countries were uncommon for most of the twentieth century. In 2000, the Vatican and Poland released a joint issue designed by Czeslaw Slania which commemorated the eightieth birthday of John Paul II. However, the early twenty-first century saw a substantial increase in joint issues. In 2003, a set released by the Vatican and Poland celebrated the twenty-fifth anniversary of John Paul II's pontificate. The following year, a joint issue of the same countries commemorated the pope's return visits to Poland. In 2005, five of the eleven stamp sets released by the Vatican were joint issues. There have also been joint issues with Germany since Benedict XVI became Pope. In 2011, the Vatican and Croatia released a joint issue which commemorated the tercentenary of the birth of Rugerius Boscovich (1711 – 1787).
Vatican Library
In 1451, bibliophile Pope Nicholas V sought to establish a public library at the Vatican, in part to re-establish Rome as a destination for scholarship. Nicholas combined some 350 Greek, Latin and Hebrew codices inherited from his predecessors with his own collection and extensive acquisitions, among them manuscripts from the imperial Library of Constantinople. Pope Nicholas also expanded his collection by employing Italian and Byzantine scholars to translate the Greek classics into Latin for his library. The knowledgeable Pope already encouraged the inclusion of pagan classics. Nicolas was important in saving many of the Greek works and writings during this time period that he had collected while traveling and acquired from others.
