Read it through once

In the course of our searches for Professor Raben and his etext we were never able to determine where copies were or which of a variety of editions he may have used as a source. We did get a little information here and there, but even after we received a copy of the etext we were unwilling to release it without first determining that it was in fact Public Domain and finding Raben to verify this and get his permission. Interested enough, in a totally unrelated action to our searches for him, the professor subscribed to the Project Gutenberg listserver and we happened, by accident, to notice his name. (We don’t really look at every subscription request as the computers usually handle them.) The etext was then properly identified, copyright analyzed, and the current edition prepared.
