Appendix 8. Heads: Guidelines for Dividing Lines

When you are proofreading lengthy heads and need to decide either where to make a break or whether a particular break is a poor one, please refer to these guidelines for assistance. The first principle is to avoid divisions that might confuse readers; the second is to avoid unaesthetic divisions. At times the only solution is to divide a head in an unaesthetic place or to break one rule to follow another; just do the best you can in the space you have. You should follow the guidelines as closely as you reasonably can. If you are proofreading, please query changes rather than marking them, unless you are absolutely certain that a break is unacceptable.
