The papers which have already been accepted by the Editors on the basis of the review process, and their contents is fixed and accepted by the Authors, are published online immediately, before the full number is closed. The retionale for such policy is to make the accepted publications accessible to the readers as soon as possible.

The accepted papers are already ascribed to the volumes and numbers, and the page numbering is known, so for a paper the full bibliographic data are already fixed. Therefore, the paper available in this mode can be easily cited. The only difference between the Accepted paper online and the other papers is that the number it appears in is not closed yet.

At present, all the issues are closed and there are no papers published according to the Accepted papers online policy.

After the paper is accepted in the review process, and the Authors provide the final version according to the Technical Requirements for Preparing a Paper, but before its contents is fixed and accepted by the Authors, the most basic bibliographic information on the paper is announced in the Forthcoming Papers panel.
