Official website descriptions of the main types for WIREs series_

Website Type	Website Description	Mapping Type
Advanced Review	These articles review key areas of research in a citation-rich format similar to that of leading review journals.	explicit review
Focus Article	These articles are mini-reviews, and which therefore illustrate aspects of larger ideas covered in Overviews and Advanced Reviews.	implicit review
Primer	Meant to be understood by a very general audience. These articles should provide orientation to the key theories, knowledge, uncertainties, and controversies in the field.	implicit review
Overview	Broad and relatively non-technical treatment of important topics at a level. These articles must refer to the key articles/books in the field (not exhaustive but comprehensive).	implicit review
Software Focus	These articles should review the capabilities of the software and how it has been and can be applied.	implicit review
Perspective	A forum for thought-leaders, hand-picked. They should cite literature which authenticates their argument(s), but without the need to be exhaustive or comprehensive.	implicit review
