A well-known Internet sociologist e-mailed me recently to ask why there is a glut of print encyclopedias. He'd been asked to edit two new ones that very week. Yet when I explain what I do at dinner parties, people often say, "You mean people are still publishing encyclopedias?" In spite of the Web and Wikipedia, some parts of the reference business are thriving. I'll try to explain why, and talk about what an encyclopedia publisher actually does and how I build relationships with experts in fields as diverse as world history, community, sustainability, and future studies. The creation of knowledge networks and tapping into international communities of experts is the key to building unique global resources, whether online or in print. I'll air some dirty laundry about reference publishing (many encyclopedias are not written by experts at all, and a surprising number are not fact-checked), and we'll discuss why and how Wikipedia is different from encyclopedias planned by a publisher and written by commissioned experts.
