I will introduce the notion of braided open books, a generalization of braids. It remains an open problem whether every fibered link in the 3-sphere is the binding of a braided open book. I will show that all fibered links in the 3-sphere whose fiber surfaces that can be obtained via Seifert’s algorithm are bindings of braided open books.
