A notification sent to customers said the company had been made aware on 10 October that it had suffered "a cybersecurity attack which resulted in unauthorised and unlawful access to certain Barnes & Noble corporate systems".
Several customers complained on Twitter that their Nook libraries had gone missing.
A Fortune 1000 company, Barnes & Noble had 627 retail stores in 50 US states as of March 2019, according to Wikipedia. It had US$3.55 billion (A$5 billion) in revenue for the full-year 2019.

However it said payment card and financial data of customers was encrypted and tokenised and not accessible.
Despite its size, Barnes & Noble has no contacts listed on its site, apart from a single general email address.
