A renaissance of virus research is taking centre stage in biology. Empirical data from the last decade indicate the important roles of viruses, both in the evolution of all life and as symbionts of host organisms. There is increasing evidence that all cellular life is colonized by exogenous and/or endogenous viruses in a non-lytic but persistent lifestyle. Viruses and viral parts form the most numerous genetic matter on this planet.

“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)
