Website designs and content are (and normally should be) significantly different from what you would use for printed materials. The advantages of linking between topics, and of providing overviews linked to details, are not available to printed media. Most printed media is designed for viewing in a more linear fashion, by drawing the reader inside, and guiding them through the message.
That doesn't mean that you have to throw out the work that went into developing your website and start over. Just as we can use existing printed materials as a starting point for developing a Website, we can also design brochures, direct mail pieces, promotional flyers, etc. using the same information that was created for your Website. This is an excellent way to develop an integrated marketing campaign, with a consistent and effective message, at a much lower overall cost.
