In 2005 an agreement was signed under which the Central Bank of Iceland handed over to the National and University Library of Iceland, for safekeeping, its collection of foreign books, periodicals, pamphlets and newspapers about Iceland and Icelandic subjects, above all Icelandic life and nature: about 2,500 volumes, together with several hundred separate pictures that had appeared in foreign newspapers and books. Among them are many travel books in which foreign visitors have described their journeys through Iceland over the centuries.
