I can relate...
From ZENIT News Agency--The World Seen from Rome:
"When receiving the news of his election, one of the nuns who looks after him told Bishop Cipriano Calderon, retired vice president of the Pontifical Commission for Latin America: 'He will have to take his library, because he goes nowhere without his library.'
A German journalist standing under then Cardinal Ratzinger's residence commented: 'For a German professor, what is most important are his books. And now he is collecting them.' "
