Bridges are structures that carry pedestrian or vehicular traffic over natural or artificial obstacles, including roads or highways, railroads, and rivers or other bodies of water. Bridges may be classified either by structure, e.g., suspension, truss, arch, etc., by function, e.g., pedestrian, highway, railroad, etc., or by material, e.g., wood, stone, steel, concrete, etc. This guide includes materials on the design and construction of bridges, as well as resources on how to manage, inspect, maintain, repair, rehabilitate, and preserve bridges.
Not intended as a comprehensive bibliography, this compilation is designed--as the name of the series implies--to put the reader "on target." A related guide, TB 08-2, Infrastructure and Public Works, which lists materials on the public infrastructure, its history and development, and proposals for its maintenance and improvement, may also be of interest. This and other recent Tracer Bullets are available online.

A lot of the talk around social media in the last year has been around information overload. Social media has provided us with new and exciting ways to create content. But it has also meant learning new ways to manage and engage with social media tools. Are we teetering on the edge of an information overload precipice?
Information overload is a figment of your imagination. Or a failure of your filter. Or a symptom of your technological submissiveness. Depends on who you ask.
What if you had to sort through 3.5 million articles and social media posts a day and try to pull out the most relevant items for your organisation? What if you then had to cobble it all together into something readable for your top groups and executives in your organisation?
