This book, the fourth in a series of Blurb books, follows the OPEN BOOKS project to its next international venue, in the Library and Archives Canada, in Ottawa, Canada. The first edition accompanied the initial exhibition of OPEN BOOKS in 2012 at the National Library of Wales, and featured books by a group of sixteen artists from the UK, Australia and Hong Kong. The second, OPEN BOOKS - CHINA, accompanied the exhibition in the Sanshang Museum of Contemporary Art in Hangzhou, in China in 2013. There the OPEN BOOKS artists were joined by 41 renowned Chinese artists in a celebration of the Chinese Folding Book. The third edition, OPEN BOOKS PLUS - AUSTRALIA was made for the next stage of the exhibition tour to Brisbane and Canberra 2014, with the addition of a group of eighteen of the Chinese artists and another five new artists from Australia. In November 2014 the Sanshang Museum of Contemporary Art produced a bilingual Chinese/English catalogue to accompany our next large joint exhibition in Hong Kong. Wherever the exhibition goes, it grows, gathering artists. In Canada we have invited thirteen Canadian artists to join us, and our Chinese friends from Hangzhou are again bringing a selection of their books. This catalogue focuses on the new Canadian artists, but each and every artist who has been in Open Books has their name and a small image of their work in the back. The new catalogue is again bilingual, in the two official languages of Canada, English and French. The Chinese folding books, each done by a contemporary artist, form a wonderfully diverse exhibition and the OPEN BOOKS catalogues chart its international journey and offer us glimpses of its development.
