Reviews

“Viruses: Essential Agents of life … is a great way to kick off the next 100 years of virology, with nary a reductionist thought to be found within its 427 pages. … readers will find many exciting reasons to be a virologist (amateur or professional) at the dawn of the 21st century.” (Welkin Johnson, Small Things Considered, schaechter.asmblog.org, January, 2013)“It is a compilation of 19 chapters, each written by one or more experts, and each comprising an overview, or opinion or essay on a different facet of the general theme. … this book offers a topically relevant compendium for biologists, evolutionary biologists, geneticists and molecular biologists interested in how viruses have contributed to host evolution and, perhaps, even to the origins of life on Earth.” (Frank Ryan, Symbiosis, Vol. 60, 2013)
