During a recent trip to Montréal, my wife and I stopped at Papeterie Nota Bene* (http://nota-bene.ca), which has the best selection of FP friendly notebooks I've ever seen. It's a very cool shop, and I highly recommend it. Anyway, we found a Clairefontaine notebook we've seen nowhere else. It's designed for science/lab use. These are A5 notebooks with Séyès ruled paper and blank sheets as well. They can be seen on the Clairefontaine site here: http://www.clairefontaine.com/subcategory-en-031033-laboratory-work-drawing-books.html Does anyone know of a United States seller for this particular notebook? Thanks! Christopher
