Emerging infectious diseases may be defined as diseases being caused by pathogens only recently recognized to exist. This group of diseases is important globally, and the experience of the last 30 years suggests that new emerging diseases are likely to bedevil us. As the global climate changes, so changes the environment, which can support not only the pathogens, but also their vectors of transmission. This expands the exposure and effects of infectious disease and, therefore, the importance of widespread understanding of the relationship between public health and infectious disease.

This work brings together chaptersthat explain reasons for the emergence of these infectious diseases. These include the ecological context of human interactions with other humans, with animalsthat may host human pathogens, and with a changing agricultural and industrial environment, increasing resistance to antimicrobials, the ubiquity of global travel, and international commerce.

The early American West has been depicted in art as a land of harsh struggles, a place of heavenly miracles, and everything in between. Different Travellers, Different Eyes records impressions of life on the nineteenth-and early twentieth-century American frontier by twenty-one artists better known for their paintings, sculptures, and photographs. Most but not all the selections come from journals or diaries kept during trips to the West.

Thomas Moran, for instance, notes what others must have felt, that "the impression then made upon me by the stupendous and remarkable manifestations of nature's forces will remain with me as long as memory lasts". That impression of grandeur echoes the vast and dramatic canvasses Moran created on his trips west.

Different Travellers, Different Eyes is not an art history book. The narrators are not art historians. Their works adorn the walls of museums, fill the pages of art books, fetch large sums at auction, and (as reproductions) illustrate histories of the early American West. Chances are slim, however, that the casual reader has read a word these artists wrote. This gathering brings the best of this literary art out of the shadows.
