Libraries in the Market of Written and Graphical Heritage

French public libraries do not play a negligeable role in the market for written and graphical heritage. New legislation put in place in 1993, following the lifting of trade barriers in Europe, has, in fact, driven these cultural establishments to assume greater responsibility in relation to the market of bibliophilia. Moreover, the sale of reproductions of ancient works equally constitutes a considerable stake, at a time when illustration agencies are experiencing technological and economic changes that are without precedent. These "economic responsibilities" of the libraries in the field of written and graphical heritage rests on specific missions, very different to those put to work in the area of the development public reading policies. Notably they allow the formation of new relations with the world of publishing.
