There are others we get - but this is off the top of my head. I go through them in about 5 minutes and rip out the articles that do or may interest me and throw the rest away. There are usually only 6-12 pages worth anything. I then put the articles in binders depending on what they refer to.
I have binders for color management, finishing, equipment, ink, materials, sales and gallery of ideas.
Most are free for industry companies.
