A letter written by the author Lewis Carroll in 1890 has been restored to Yale University’s Beinecke Rare Book and Manuscript Library after a librarian noticed a description of the document on the Internet auction site eBay, The Hartford Courant reported. The eBay seller, a Utah-based collector who had purchased the letter from another seller without knowing it had been stolen, returned it to Yale after discovering its shady provenance. The campus police are investigating how and when the letter was stolen.
