Visual design is an information delivery system and the smoother that delivery, the better the design. One of the strongest tools we have to facilitate information deliver is hierarchy. Visual hierarchy helps ensure that your most important information is seen first and that viewers are able to take in the amount of information they want quickly and easily.

I'm pleased to announce that the Data Source Handbook is now available from O'Reilly. It's a compact ebook guide to the most useful APIs and bulk data sets I've found, packed with examples and advice. These are hand-picked services that I've actually spent time using during my own work, and I chose them because they add insights and information to data you're already likely to be dealing with. You can check out the table of contents below, and I've also included a couple of excerpts.
It's organized by the kind of data that you want to look up information on, from websites to locations, email addresses to ISBNs.
