Retread
Jargon Guides
A "retread" is a project which has gone through one or more DP rounds and then was re-proofed through the same round or rounds. This may happen for several reasons, the most common of which is to bring a project up to the current proofreading guidelines.
In 2005, many projects were "retreaded" as part of the major updates to the DP site when moving from a two-round process to a four-round process, i.e., "The Change".
Retread projects are marked with an "{R}" [previously, an "(R)"] in the project title for easy recognition and automatic detection by the site software.
