This focus issue of the journal draws attention to “Collections in a Digital Age.” The essays are, like digital public history itself, multi-faceted showing a variety of possibilities, opportunities, challenges, and best-practices at a range of institutions or dealing with an assortment of historical materials. The contributions are drawn from working group activity at the April 2015 annual meeting of the National Council on Public History.

They were known as Unofficial Player guides, but were considered the best collection of new information, variants, scenarios, rules variations, errata, inserts, and new articles written for these games. Fans loved the materials, because it delivered new life into a game that was forgotten by Avalon Hill, but still cherished by the players.

Cyclogenesis research is a central issue of meteorology and climatology. This book gives a deep specific view and fundamentally and effectively contributes to the discussion of the problem. It treats cyclogenisis as a stochastic process in a very fundamental way. Since the publication of the first edition of Global Tropical Cyclogenesis in 2001, a number of important scientific results has been obtained using methods and techniques proposed in that first edition. There is therefore a great need for a revised 2nd edition of this book. It is based on scientific findings from the performance of satellite data processing and a series of scientific marine expeditions to the tropics as part of major Russian Science Academy research projects. Professor Eugene A. Sharkov has proposed the main approaches, experimental techniques and theoretical explanations for many scientific findings as well as new methods of satellite processing. He is recognized as a leading scientist in the field of microwave remote sensing of terrestrial surfaces and atmosphere and in nonlinear geophysics (origination and evolution of atmospheric catastrophes) and has published around 100 scientific works on the problems of global tropical cyclogenesis structure and evolution.
