Citation, Documentation of Sources

Q. My book has three parts, and each part contains several chapters. Here is the question: do I need to give full publishing information in each new chapter for items cited earlier in the same part, or can I use the short version of citing (as I do within each chapter)?

A. If you have a bibliography, you can put short citations everywhere—there’s no need to give the full information in the notes. If you don’t have a bibliography, readers are best served by your starting over in every chapter with a full citation upon first mention (parts are irrelevant). Otherwise, they will go mad trying to find the original citation.
