This template takes an optional id parameter, heading and page number or numbers for the MSW3 entry on the species or other taxon in question.
For example:
{{MSW3 Helgen | id = 12600004 | page = 842}}

for the American beaver, Castor canadensis (the title link goes to the MSW3 web page for the species entry).
In the following example, a heading is used:
{{MSW3 Helgen | id = 11900002 | pages = 104–107 | heading = Family Tupaiidae}}
giving
Helgen, K.M. (2005). "Family Tupaiidae". In Wilson, D.E.; Reeder, D.M. (eds.). Mammal Species of the World: A Taxonomic and Geographic Reference (3rd ed.). Johns Hopkins University Press. pp. 104–107. ISBN 978-0-8018-8221-0. OCLC 62265494.
for Tupaiidae (the heading link now goes to the MSW3 web page for the family entry, while the title link goes to the Google Books preview for MSW3).
Helgen contributed the following sections to MSW3: Order Scandentia, Family Aplodontiidae and Family Castoridae. When no heading is employed, it may be advantageous to use instead one of the more specific taxon-based templates ({{MSW3 Scandentia}}, {{MSW3 Aplodontiidae}} or {{MSW3 Castoridae}}), which supply a default chapter heading.
An optional |ref= parameter is supported but seldom used. It allows specification of reference names in Harvard references, for use in the {{citation}} template family. For example, use of |ref={{harvid}} or |ref={{SfnRef}} templates enables subsequent use of short-format templates like {{harvnb}} or {{sfn}} (see Yarkand hare and Long-tailed vole for examples of usage).
