Not long after selling his collection to the Library of Congress in 1906, Yudin started a new library, voraciously acquiring more books and other print materials until his death in 1912. Although a precise estimate for this second collection is difficult to determine, it likely consisted of around 5,000 items. This second collection was also comprised of items Yudin did not include in his sale to the Library of Congress, such as books belonging to family members or those which were dedicated to Yudin.

During the Soviet era, the majority of items in this "second library" were transferred to the Krasnoiarsk Region Universal Research Library (KGAUK) where they remain in that library's Rare Book unit. Some items from Yudin's "second library" can also be found in libraries in Moscow and St. Petersburg, such as the Russian National Library and its collection of erotica from Yudin. Since 2000, KGAUK hosts an infrequent conference dedicated to Yudin as well as to broader issues about book history and preservation.
