Some authors cannot or will not submitto journals that assess page charges. Even if funds are available, page charges divert monies from research. If page charges can harm the quality of the journal by discouraging submission of good papers, and if they limit the amount of research possible, why do page charges exist? More importantly, why are page charges an integral part of the income strategy for AGU publications?

Page charges help keep subscription rates down; in particular, they permit the circulation of large amounts of material to individuals at very low rates. Additionally, page charges reduce to some extent the dependence of the number of pages published on the subscription revenues. Furthermore, page charges will provide a financial base for experimentation with and adaptation to future information dissemination technologies.
