Exploring & Collecting History Online (ECHO) Who decides what makes it into the history books? It's one thing to read a one-sided news article or textbook account of events that impact us, whether it's the Columbia tragedy, the Apollo lunar missions, or the advent of computers and the Internet. It's another thing entirely to share your own first-hand account of these pivotal moments. That's what this site is all about. Its mission is to pool our collective Memory Bank and create a multi-faceted, engaging record of science and technology history. We quickly learned about trailblazing geneticist Barbara McClintock while digesting a primer on Artificial Intelligence. Want to create your own online soapbox? ECHO offers a practical guide to building a history site, with technical tips on picking a platform and sustaining a community. Don't leave history to be written by a chosen few. (in Science History)
