Map reference

Reference list

The APA does not provide detailed advice on how to reference maps produced by online services. We recommend the following as consistent with APA practice for referencing. Advice for using Digimap services can be adapted for other online map services.

Maps produced by Digimap can be identified by the elements listed below which are displayed when viewing maps.

Creator	Digimap
Date	If available, this is the date the original map data was compiled.
Description	As there is no title, provide a short description in square brackets. [This should include keywords, coordinates or grid references that can be used to find the central feature of the map.]
Digimap Service	Treat as series title, in round brackets after description. For example, (Roam, Environment Roam, Ancient Roam)
Map product	If available include with Digimap service in round brackets. For example, (OS MasterMap, Land Utilisation Survey of Britain (Dudley Stamp))
Web address	Retrieved from http://digimap.edina.ac.uk

The reference should be in the following format:

Creator. (date). [Description] (Digimap service, Map product). Web address

Example references

APA Referencing does not require you to include the scale but you can add it to the description if this will be helpful to your reader
The date may be a single year, a range of years, or year and month
If there is no date use (n.d) for no date

If you have a source with more than one author, if the author is an organisation, or if you cannot identify an author, follow this guidance.

Citing authors with example references

Examples in this table are selected to show how to cite and reference names. The approach to names is the same for all types of reference and you will see different types of reference from the main example at the top of the page.

	Citation	Reference
One author Cite and reference the author	Phillips (2006) or (Phillips, 2006)	Philips, D. (2006). Quality of life: Concept, policy and practice. London: Routledge.
Two authors Cite and reference both authors	Kimball and Ross (2002) or (Kimball & Ross, 2002)	Kimball, R., & Ross, M. (2002). The data warehouse toolkit: The complete guide to dimensional modeling. New York: Wiley.
Three, four or five authors Cite all authors in the first citation. Subsequent citations should include the first author followed by et al. In your reference include all the authors.	Bott, Coleman, Eaton and Rowland (2001) or (Bott, Coleman, Eaton & Rowland, 2001) Bott et al. (2001) or (Bott et al., 2001)	Bott, F., Coleman, A., Eaton, J., & Rowland, D. (2001). Professional issues in software engineering (3rd ed.). London: Taylor and Francis.
Six or seven authors Cite the first author followed by et al. and in your reference include all the authors.	Shepperd et al. (2009) or (Shepperd et al., 2009)	Shepperd, S., Doll, H., Gowers, S., James, A., Frazel, M., Fitzpatrick, R., & Pollock, J. (2009). Alternatives to inpatient mental health care for children and young people. The Cochrane Library, (2), article number CD006410.
Eight of more authors Cite the first author followed by et al. In your reference, include the first six authors, followed by ... then add the last author.	Mali et al. (2013) or (Mali et al.,2013)	Mali, P., Yang, L., Exvelt, K., Aach, J., Guell, M., Dicarlo, J., ... Church, G. (2013). RNA-guided human genome engineering via Cas9. Science, 339(6121), 823-6.

Editors

Follow the pattern above for when you have an editor or editors of a work; just remember that in your reference you need to identify them as an editor by putting (Ed) or (Eds) after all of the editors in the reference.

A source can be written by a corporate author such as an organisation or a company, also known as a group author. The corporate author and year should be used in the citation.

Citation	Reference
Joseph Rowntree Foundation (2013) or (Joseph Rowntree Foundation, 2013)	Joseph Rowntree Foundation (2013). Free school meals announcement - JRF response. Retrieved from: https://www.jrf.org.uk/press/free-school-meals-announcement-jrf-response

For instances of more than one corporate authors of a source, treat them as you would two individuals in the reference (i.e., include both). The group author names should not be shortened in the text citation. However, if they are used repeatedly, you might introduce an abbreviation.

If you cannot identify the author(s) of a source, cite it by title and list it under the title in your reference list.
