The “steel bible” emerged in 1919 and went through 11 editions in 80 years. In its evolution we can see the shift from individual to group authorship, an increasing use of visual elements, and a physical change from a small, hand-held volume to a weighty desktop reference. In a textual analysis, we can see that it was essentially static, changing only by additions and deletions, as the industry evolved. The eventual closing of hundreds of plants and the migration of the industry to other countries can be seen in the change of publisher, the sudden absence of photography, and the international references. Originally, the steel bible came from the factory floor and the words of the plant managers, but by the 1990s, it was a highly-abstracted representation of knowledge. In the steel bible, we can see the history of the industry and the maturing of technical communication in the 20th century.

Over a period of 10 years, we have developed a sustainable process of online portfolio assessment that demonstrates both reliability and validity, using both qualitative and quantitative measures. The sustainable cycle is that, each semester, we assess a random sampling of the students' work that they have posted, as per our instructions, in an online portfolio. During the reading, the faculty score the documents for 11 variables, including writing, content, audience awareness, and document design. We achieved validity by a modified online Delphi that led to a redefinition of the construct of technical communication itself; we achieved reliability by adjudication resulting in adjacent scores. The results of our assessment meet the requirements of ABET and result in a continual cycle of improvement for our technical communication curriculum. Results from three semesters show an improving correlation between the course grade and the overall, holistic portfolio score.

Examing the discourse surrounding the charcoal iron industry between 1760 and 1860 in North America, this article suggests that, prior to the industrialization of work, technical communication took place in a prediscursive setting, an oral and physical world that we can just manage to glimpse even as we watch it recede. The letters of Robert Erskine written in 1770 illustrate the prediscursive methods of technical communication. By the 1860s, a flood of governmental, professional, and commercial publications appeared, each signifying the disappearance of this prediscursive world. This transition from prediscursive to discursive methods may mark one of the largest changes in the history of technical communication.
