More than just a ten-year count, the US census is a collection of high-quality, geographically detailed, and free and open datasets that describe the demographic and socio-economic characteristics of the nation on an on-going basis. This issue of Library Technology Reports provides readers with a crash course on the census: learn about the concepts on which the census is organized, the key datasets, accessing data online and through scripts via APIs, and considerations for using GIS, historic data, and microdata. Librarians will gain knowledge they can use for assisting members of their communities with census data, and will see how the census can be used for library planning and research.

In recent years there has been an evolution in numerical models used to compute tsunami propagation and run-up. Many models currently available offer a wide array of choices to the users. In parallel with the development of such numerical models, it is important that the user only applies the verified and validated numerical models that have undergone a benchmark analysis. This publication provides information and benchmark problems to enable engineers and regulators to select the most appropriate tsunami analysis software and modelling for the evaluation of tsunami hazards for nuclear installations to ensure their safety against those events. In addition, the benchmark problems will enable such users to become familiar with the limitations of the tsunami analysis modelling available in research and commercial software.
