Citing an article in ERL

ERL uses an article numbering system which allows articles to be added to an issue one at a time, while maintaining separate sections for editorial material, Perspectives and Letters. Articles should be referenced by using the six-digit article number in place of a page number, for instance:

Kammen D M 2006 Environ. Res. Lett. 1 010201

The pages in the PDF file of each article are numbered from 1. These page numbers should not normally be included in a reference. However, if it is desirable to indicate the length of an article, this can be done by including the number of pages, in parentheses, after the article number, for example:

Kammen D M 2006 Environ. Res. Lett. 1 010201 (3pp)

Each article in a volume has a unique six-digit number, the first two digits indicate the issue number, the next two the type of article and/or its subject area and the final two are a counter indicating the sequence number for the article within its issue and category.
