RSM Press have started to publish articles online ahead of print in a feature called Online First. These articles have all been through the peer-review and pre-press processes and will not change prior to print publication. The date of online release is noted on the website alongside the other article details and is the official date of publication. You can use the CiteTrack feature to set up an e-mail alert to notify you as soon as the article you are interested in is published in print.

When papers appear in print, they are removed from Online First and grouped with other papers in an issue. The official publication date appears below each title (e.g. Ann Clin Biochem 21 August 2008), followed by the Digital Object Identifier (DOI), an automatically generated unique identifier for intellectual property in the digital environment (e.g. 10.1258/acb.2008.008037).

A sample citation for Online First articles:
Lang T. Audit of acute hypoglycaemia in children: re-audit of procedures for diagnosis. Ann Clin Biochem Epub Ahead of Print: 21 August 2008. DOI 10.1258/acb.2008.008037.

Once papers appear in print, cite them as usual:
Barth JH, Marshall SM, Watson ID. Consensus meeting on reporting glycated haemoglobin and estimated average glucose in the UK: report to the National Director for Diabetes, Department of Health. Ann Clin Biochem 2008;45:343-44.
