Largest collection of books autographed

The largest collection of autographed books consists of 2,652 books and is owned by Wioleta Sadowska (Poland), in Zofiówka, Poland, on 3 July 2026.

A passionate book collector, reading promoter and book blogger, Wioleta has been involved in book marketing and the promotion of reading for 15 years. She began collecting autographed books in 2011, starting with Noelka by Małgorzata Musierowicz, and her collection has continued to grow ever since. Her favourite book is Nowe przygody Pana Samochodzika by Zbigniew Nienacki, which helped spark her fascination with literature. Each book in the collection is unique and personally signed by its author. By achieving this record, she hopes not only to fulfil a long-held ambition, but also to celebrate Poland’s strong reading culture and inspire more people to discover a love of books.
