Airshipsonline exists to provide viewers with access to the archives of the Airship Heritage Trust. The trust was originally established by enthusiasts and relatives of crew members, and continues as an effort to preserve airship history. The site includes a vast array of information relating to all aspects of lighter-than-air technology, especially in the U.K. Uninitiated readers can visit the online reference section to read an elaborate history of airships in general, or individual models. There is also an online discussion forum, dozens of images, and 25 short movie downloads created from original film footage of ships flying, landing, and "on the mast." Designs and flight plans are interesting features of the site as well. The material is not searchable, but a helpful index allows users to jump directly to the information they need, and the site provides an long list of related links with notes.

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.

An interactive cartographic history of the relationship between hydrological and hydraulic systems and their impact on the urban development of Rome, Italy from 753 BC to the present day.

Illustrated review by Yoshitaka Mouri in Art Watch of the Royal Academy of Arts exhibition on inhabited bridges, including historical examples and past utopian bridge plans.

The University of California at Berkeley has compiled a sizeable archive of slides of work by Leonhardt, Andrä and Partners of Stuttgart, Germany. Images are categorized according to their architectural characteristics, the type of material used, or the type of structure pictured. Text content also details some of the structures pioneered by the architecture firm. Useful for architectural case studies and research.

This page is one in a series of biographies about famous civil engineers. The American Society of Civil Engineers (ASCE) tracks the path of Conde B. McCullough’s, including his influential post-WWI stint as head of the Oregon Department of Transportation and the architectural tendencies he acquired during that time. The link to photos of the architect's work returns nothing but a blank page; however, the Rogue River Bridge (mentioned in the body of the page's text) has a link to a picture and a description of the structure. Clicking the "resources" link brings up a modicum of recommended reading to spur on any aspiring researchers.

This Digital Bridges page contains a facsimile of the illustrated pamphlet of wrought iron bridges built by this Ohio Company. However, unlike several other period bridge-building company pamphlets, the Wrought Iron Bridge Company focuses on images rather than text, leaving an aesthetic record of railroad bridges where other pamphlets tend to give a technical record. A worthwhile primary source for those seeking graphic representations of 19th century bridges.

Facsimile of this 1873 publication of railway bridges. Produced by Clark, Reeves & Co. before change to Phoenix Bridge. Also available in pdf and tiff formats.

This archived Digital Bridges document reviews some engineering techniques on the forefront of bridge-building technology in the late 19th century. Like many similar period documents, the bulk of the work is textual and the sentences too convoluted for casual reading; the document was likely intended for readers already educated in the subject. However, there are also some useful lithographs in the book, and the entire document shows the direction in which engineers believed bridge-building would be headed in the coming years.
