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.
Redlinks
Non-existent articles will not be included in book. Please create the article, or remove it if the redlink is the result of a deletion. There is are no negative effects to having redlinks in a book, so useful redlinks should be kept.
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 ... -->
