The Library of Congress initially learned about Yudin's collection through an advertisement placed by Yudin in The Washington Post in 1903. In 1902 the Library of Congress had hired a Russian émigré, Alexis Babine, to work as a specialist in Slavic literature. Due to his language and cultural expertise, Babine was instrumental in negotiating the acquisition of the Yudin collection in 1906.

When the collection arrived at the Library of Congress in early 1907, Herbert Putman, the Librarian of Congress at the time, remarked it was the year's most significant acquisition. The acquisition also caught the attention of then President Theodore Roosevelt, who echoed Putnam's sentiment. Below are resources on the acquisition of the Yudin collection by the Library of Congress, including primary sources related to Alexis Babine. Also listed are resources on the history of the Yudin collection since its acquisition by the Library of Congress.
