Redirects
A redirect in a book is not necessarily a problem. For example Richard P. Feynman redirects to Richard Feynman is not a problem redirect because it points to the intended target. However a redirect, such as Nicole (Dead or Alive) to List of characters in the Dead or Alive series#Spartan-458 (Nicole), is most likely problematic, as it will include the List of characters in the Dead or Alive series article, and not Nicole (Dead or Alive) as it once stood. As such, it is good practice to ensure that books include no redirects, if only so this notice doesn't show up.
Duplicate articles Duplicate articles are articles that are included more than once. These are usually the result of redirects to the same article, and unintentional. Although this should not happen very often, it is possible that some articles are intentionally duplicated. Mark these with a comment below the link, such as: :[[Hydrogen]] <!--This article is intentionally included twice in the book because ... -->Comments on the same line as the link will cause the article to be ignored by the PDF.
:[[Hydrogen]] <!--This article is intentionally included twice in the book because ... -->
Parenthesis in article titles
Parenthesis in article titles are usually due to a need to distinguish between two similarly named topics. However in books, context is often clear enough that the parenthesis are superfluous. For example in a book on basketball Robert Smith (basketball) can be renamed Robert Smith without confusing the reader. To do this, simply write [[Robert Smith (basketball)|Robert Smith]]. Although this should not happen very often, it is possible that some articles should keep their parenthesis. For these, simply write :[[Robert Smith (basketball)|Robert Smith (basketball)]] <!--This Robert Smith can be confused with Robert Smith (baseball), also present in this book -->This will let editors (and WildBot) know that this is intentional. The comment must be below the link, if it is on the same line, the PDF will ignore the article.
:[[Robert Smith (basketball)|Robert Smith (basketball)]] <!--Can be confused with Robert Smith (baseball), also present in this book -->
