This site chronicles how Charles Dow devised the now famous Dow Jones stock averages, and how they developed from 1884 to 1995. Besides terminology that may sometimes leave the uninitiated scratching their heads, this site is a good starting point for understanding the history and function of today's stock exchanges. The short and rather basic story of Charles Dow's average is supplemented through links to information such as lists of companies tracked by each of the Dow Jones averages, an explanation of the OTC market and Nasdaq, and listing standards for the New York Stock Exchange. A table also lists historical records for the NYSE. The navigation within the site is not facilitated by tabs, a side bar, or search tool, but the site is small enough to navigate easily.

This site, dedicated to the history of a Turkish aircraft industry, gives a summarized version of the material available in a book by the site's author, an aviation enthusiast who was born in Turkey and grew up in Germany. The site has a very basic design and the navigation is difficult because the pages are labled in many cases by Turkish names and acronyms that are not readily understandable by an english-speaking audiance. Also, each page is not cross-linked, so viewers will have to back-click to the first page before continueing to each following section. But despite the navigational difficulties, the site does offer some interesting information about the Turkish government's interest in aircraft and the partnerships between Turkish groups and foreign manufacturers. The site includes tables that list aircraft licenced for production in Turkey, the years of production, and the actual numbers produced. There are also a few images.

Story of Ammann's influence in the construction of bridges in New York. Includes a photographic tour. From the Public Broadcasting Service.

UC Berkeley's online exhibition includes descriptions of and artifacts related to every major San Francisco Bay-area bridge; however, it devotes a significant amount of space to Joseph Strauss's plans for the Golden Gate Bridge. The Golden Gate section has five subsections - "Design & Construction," "Politics & Financing," "Toll Plaza," "Celebration," "The Color," and "Art & Icon" - each featuring photographs, architectural drawings, newspaper advertisements, and paraphernalia of all sorts from the bridge's inception. A useful resource for students looking for American historical artifacts for the World War II and postwar era, particularly for research purposes.

This PBS website, made for the program "The American Experience," is a tome of material relating to the life and career of engineer James Eads. Material includes a transcript of the television show; a list of further reading on Eads; a Flash demonstration of how to build a bridge pier; letters from the Eads family; a gallery of architectural drawings; links to descriptions of the people and events discussed in the program; and a brief section on the Mississippi River jetties today. The site is likely the most extensive archive any researcher will find on Eads, and it is an indispensible resource for anyone looking for information on the Mississippi River engineer.

This Library of Congress page gives a brief history of John A. Roebling and the construction of the Brooklyn Bridge. However, its primary feature is a series of links to primary source documents in the LOC archives, including interviews, footage, and extensive photographs. The page also links to a bibliography of books and web resources on the Brooklyn bridge.

This page is part of a tome of photographs, technical descriptions, and stories about the World War II escapades of the 150th Combat Engineer Battalion. Each bridge that the group constructed during the war has its own section, along with numerous images of the structures. Though some photos are on loan or have been taken in recent years, the vast majority come from the site founder's father, who served as the battalion's electrician, scout, and photographer until the war's end. In response to requests for information on lost family members, the webmaster has also posted links to and information about resources for military families, as well as logistical information about 150th battalion reunions.

This page, one of many articles on the "War Times Journal" website, tells the story of the impromptu bridges built over the Berezina River by retreating French forces in 1812. Though author James Burbeck does not adequately contextualize the incident within the Napoleonic Wars, his article provides a detailed description of the construction and the events that followed. The site also includes a computer simulation of the footbridge, a painting of French troops and families crossing the river, a map of the region, a copy of a letter from a French Major General to Éblé, and a brief list of recommended reading.

Making the Modern World is a vast online exhibit from the Science Museum of London that covers science and society in the modern era, from traditional research and inventions and engineering, to social sciences and everyday life. There are many ways to explore the hundreds of images, audio files, and texts of the exhibit that begins with “Enlightenments and Measurement” in 1750 and concludes with the “Age of Ambivalence” in 2000. The largest section of the site is the Stories and Timelines, which is in narrative and chronological form. There are guided tours along the themes of “Technology as Passport,” “Women Making the Modern World,” and “Conflict in the Modern World.” The Daily Life Section has six categories that include personal, leisure, work, health, and control, and the stories of nine contemporary people's interactions with technology, some inventors, others learning how to handle a screwdriver and "DIY- Do It Yourself." The Icons of Invention includes more than 100 objects from science, technology, and medicine, while the Learning Modules cover biology, English, chemistry, geography, history, mathematics, and psychology. Throughout the site are subsections called "rich media scenes" with moving images and sound that provide interaction with catalogued images and quizzes within a particular story. Finally, there are basic and advanced search options to navigate quickly to a particular item or term.
