years, Découvertes finally surpassed the difficulties. The end of 2006 is marked by the celebration of the collection's anniversary and the publication of its title . A website was specially created on this occasion, which is the current official website http://www.decouvertes-gallimard.fr. On the occasion of Éditions Gallimard's centenary in 2011, the title ('Gallimard: A Publisher at Work') was launched as the first e-book for iPad of "Découvertes". This was followed by an e-book collection consisting of À la recherche de l'Égypte oubliée, , , Léonard de Vinci : Art et science de l'univers, and in the next year. Image Image (illustration, designated as in French) is the essential part to Découvertes Gallimard, the collection draws much inspiration from magazine layout designs. Full colour pictures, documentary illustrations, archival photographs, historical maps occupy a central place in this work, as said Pierre Marchand himself: "the language of images is a universal language". But in the 1980s, desktop publishing and photo digitisation did not exist, the sophisticated mockups were entirely handmade and the iconographers ran around museums, libraries, painting galleries and other agencies to look for documents. Today, the technology has simplified all these procedures but the difficulty lies elsewhere, the status of the image is increasingly complex. Contemporary subjects often generate much higher costs since the publisher is obliged to work with photographic agencies. In the choice of documents, priority is given to those original, unpublished images. Besides, the iconographers of Découvertes have some exceptional documents, such as English explorer Frederick Catherwood's original drawings of Maya ruins decorate the title Les cités perdues des Mayas. It's not difficult to illustrate subjects like arts, civilisations, archaeology... But when it comes to a topic like "pain" ( – ) or "sustainable development" ( – ), it becomes more delicate. The question is how to avoid repetitiveness or the flatly illustrative image, the solution lies in a broadening field, through the use of historical documents, works of art and film stills. Case study of aestheticisation movement The aestheticisation of postmodern everyday life, according to sociologists Michel Maffesoli and Mike Featherstone, it seems to spring from two parallel movements rooted in modernity, the so-called "dual postmodern aestheticisation movement": first an aesthetic hedonism (Maffesoli) and second the trivialisation of art (Featherstone). The second movement is the result of the de-academisation and de-institutionalisation of art, thus "art is part of everyday life". Découvertes Gallimard is considered an example
