Design Reading
There's a wide selection of books below. I've tried to pick a variety across books for designers, branders, copywriters, creative thinkers and marketeers. And there's the odd legend in there too for good measure. I will no doubt add to this list as new books are published or they simple cross my desk and I get time to read them!
All of these will make you better at what you do. They will expose you to new ideas and challenge your existing ones. After all that's what reading is all about. Some you will zip through cover to cover, others you'll come back to when needed. Many you'll dip in and out of for years to come. I'm obliged to mention that I may make a small amount from links on this page should you buy the items. Some of the books are pricey so feel free to get the used or returned editions wherever you can.
