A correction helps readers identify an error in a particular edition. A clarification explains a passage more fully. A later paper may develop a new argument or revise an earlier position. Keeping these kinds of update distinct makes it easier to follow how the work develops.
Finding the Relevant Entry
Use the book title and edition to identify the entries relevant to your copy. A correction should state the chapter, section, page, table, or equation affected, give the corrected information, and explain whether the change affects the argument or a result.
Page numbers can differ between formats. Where possible, a section title and a short identifying phrase provide a second way to locate the passage.
Supporting Materials
A supporting resource should explain which book or argument it accompanies and what it contributes. A diagram may make a distinction easier to see; a derivation may supply intermediate steps; a notebook may implement a specified calculation. Each has a different purpose.
Technical resources should identify their version, assumptions, and connection to any reported result. A demonstration or toy model should remain distinguishable from an analysis of observational data. Plans for future research are useful resources, but their existence does not mean that the research has been completed.
Reporting a Possible Error
Please include the book title, edition or format, and the location of the passage. Quote the relevant wording briefly and explain the issue. For a calculation, identify the step in question and, if possible, show the alternative calculation. A clear report makes the problem easier to examine and the eventual correction easier for other readers to use.
