YABS is the sister seminar of the long established Colorado Antiquarian Book Seminar and was created with the support of the Colorado faculty. YABS was set up when Anthony Smithson, of Keel Row Books, attended the Colorado seminar in 2011 and was so impressed with the intentions, execution and results of the Colorado seminar that he decided to answer the glaring need for a European equivalent.
Anthony developed and launched YABS in 2014 with Alice Laverty (also of Keel Row Books) and Jonathan Kearns, of Jonathan Kearns Rare Books and Curiosities. YABS 2019 will be the sixth annual seminar. The event is still managed by Anthony and Alice of Keel Row Books, with the support of the ABA office with the help of York-based event manager Sophie Pointon.
