Bouquinistes is the French word to call sellers of old books along the Seine River in Paris. The tradition has existed for over 400 years. However, modern technology like electronic book readers and sellers of books online are now hurting their profits and threatening their existence. To save the trade, the bouquinistes are now trying to be added to UNESCO’s Intangible Cultural Heritage list. The list recognizes and protects traditions and living expressions passed on from family members. David Nosek is one such bouquiniste. He is busy reading a book and rarely looks at the tourists walking by. A few stop to examine old books and artworks on his green metal stand. "I like to read, I like old things, and there's an independence to the business," he said. We certainly don't get into it to get rich. Sophie Leleu supports the effort to be added to UNESCO's Intangible Cultural Heritage list. She thought it would be a good way to maintain the quality of the trade.
