  This paper describes a five-step procedure for meta-analysis. Especially important was the contacting of authors of prior papers. This was done primarily to improve the accuracy of the coding; it also helped to identify unpublished research and to supply missing information. Application of the five-step procedure to the issue of return postage in mail surveys yielded significantly more papers and produced more definitive conclusions than those derived from traditional reviews. This meta-analysis indicated that business reply postage is seldom cost-effective because first class postage yields an additional 9% return. Business reply rates were lower than for other first class postage in each of the 20 comparisons.

  Description
  Real stamps improve the return rate. Surveys using business reply postage are less effective.
