Below are links to sites with information or tools related to marketing and design. (These links open in a new window.)
The Designer's Toolbox > The Designer's Toolbox is an indispensable repository of tools and information for designers. It offers standard print format templates and sizes, mailer guides, standard web banner sizes and much more.
Da Font > An enormous repository of free fonts, sorted by name and theme. New fonts added most weeks.
What the Font? > One of the best online tools I've ever found. Upload an image of some text and the site will try to match the font face.
A List Apart > A monthly online web design & development magazine.
Seth Godin's Blog > Seth Godin is the best selling author and entrepreneur. His blog shares his thoughts on marketing and business, and is an invaluable source of ideas. I recommend subscribing to the RSS and reading it every day. I do.
