The "National Library" mentioned in these accounts is not specifically identified by name, but at the time the library then known as the "Preußische Staatsbibliothek" (Prussian State Library) had that function. Situated on Unter den Linden and today known as the Berlin State Library ("Staatsbibliothek zu Berlin"), this was the largest scientific library of Germany. During the war, most of its collection had been dispersed over some 30 separate storage places across the country for safe-keeping. After the war much of the collection was returned to the library. However, a substantial number of volumes which had been sent for storage in the eastern part of the country were never recovered, with upwards of 350,000 volumes destroyed and a further 300,000 missing. Of these, many ended up in Soviet and Polish library collections, and in particular at the Russian State Library in Moscow.
