George W. Gokel,Stephen H. Korzeniowskirs: periodicals and institutionally supported lectures. While my focus will be on the early nineteenth century, the conditions within which the more ephemeral print forms developed and the audiences to which they appealed suggest the usefulness of some preliminary attention to their antecedents.

Emerging societies, he suggests, respond to the past with an attitude of “estrangement and aversion” (265) that reflects embarrassment at their proximity to the culture they wish to supersede.
