Scientists in astrophysics and cosmology make much use of the arXiv repository. Concerns raised by scientists in those fields about publication costs and delays, and the transparency and validity of the peer review process, raised questions about levels of satisfaction with existing publishing models. This paper discusses the results from a community survey in the fields of astrophysics and cosmology, conducted as part of an investigation into the feasibility of an "overlay journal" model in these disciplines. Six hundred and eighty three (683) researchers provided information about their academic/research background, their research practices, and their attitudes, both as producers and consumers of information, to the traditional journal publishing system, and gave their reaction to the overlay publication model. The survey results indicate that scientists in these disciplines are, in general, favourably disposed towards new publishing models, although some important caveats ...
