Contributions should be consistent with these general goals. Notes for contributors appear below. All articles submitted will be refereed by peer reviewers. While final responsibility for the acceptance or rejection rests with the editor, responsibility for opinions expressed or data introduced is always the authors’.

Selected manuscripts will be sent to commentators and their reviews may be published in order to promote scholarly debate, in which case the author will be invited to respond to these comments. In addition to articles reporting original research or review of significance, the submission of brief reports, conference reports, book reviews and bibliographical entries is also invited.
