I've myself have lots of notebooks, full with math and physics notes, from high school and uni that i keep on my shelf. I ve used regular notebooks, 60 80 100 pgs, squared and i find that organizing them is a real mess!They bend, curl, tear and deteriorate. So i've been thinking about some alternatives and i found this Moleskine notebooks http://www.moleskine.com/en/collections/model/product/squared-soft-notebook-extra-large.They [Broken] run kind of expensive but they have a really good construction grade and can very elegantly be stored(http://www.notebookstories.com/wp-content/uploads/2013/02/outras-009.jpg). Another brand that i've found is Leuchtturm1917 but they're a bit hard to find here in my country. What about you guys?What do you use to store your information? Do you know any other notebooks with similar format and that are as robust as Moleskine(and maybe a little cheaper)?
