ECHO (Exploring and Collecting History Online) is a directory to 5,000+ websites concerning the history of science, technology, and industry. You can search it, browse it according to category, or even look at the tag cloud we've generated. Every website contains a brief description (some examples are here), and occasionally, a review (like these).

Paul Ehrenfest, Albert Einstein, W.M. Elsasser, Poul Sophus Epstein,

Annotation: 

This site is the online guide to the Niels Bohr Archive. The archive houses thousands of records concerning the famous physicist and the development of quantum physics. Most of the textual primary documents are not available without arranging a visit to the archive; however, a few previously unpublished letters between Bohr and German physicist Heisenberg are available in facsimile, transcribed, and translated. The site's most extensive materials are many pages containing a huge number of images of Bohr, his friends, family, and colleagues. The images are searchable and organized into smaller categories to assist browsing. The site also provides essential information on preparations required before visiting the archive. These procedures seem very particular and restrictive, so the site could be a crucial tool for avoiding delays when planning a research trip. Thus, the site is a valuable resource for any researcher looking for images or working on the history of quantum mechanics, atomic energy, and the life and career of Niels Bohr.
