LITERATURE REFERENCES
using the Harvard System


There are several accepted conventions for citing bibliographic references. The method described here is the Harvard System. It is the one most commonly used in scientific papers.
NB: Citations in papers submitted to scholarly journals should always follow the method used by that journal.

Introduction

In the course of your literature search you are likely to find many publications which contain relevant information. It is important that you record their full bibliographical details in order to be able to identify them easily at a later date. These details are known as bibliographical references.

There are many different ways in which bibliographical references are set out by other authors. In order to avoid producing an inconsistency in your own work it is important to choose one style and stick to it. Therefore you should 'translate' any references you find into your chosen style. If you are preparing a paper for a particular journal you must of course follow the style used by that journal.

Remember the basic rule is that references should be correct, complete and consistent.

Within your own text you will be expected to acknowledge where you have used any sources (e.g. books, journal articles, conference papers etc.) to provide ideas, support arguments or for direct quotations, by citing the documents, from which you obtained the information, at the point of use.

At the end of your project or dissertation the bibliographic details of all documents cited are listed under the heading References or Material Cited. Do not include any references which are not cited in the text. If you wish to indicate other useful publications for background or further reading these are included in a separate list entitled Additional Reading or Bibliography.

Why you need to cite references

NB: To include other authors' work in your own, or to "borrow" others' ideas without acknowledgement is known as plagiarism. This is easier to detect than you might imagine and is regarded as a serious misdemeanour.
Any evidence of plagiarism will certainly count against you when your work is being assessed, and could result in you failing your course.


CITING REFERENCES IN A TEXT

The following guidelines explain :-

a) how to cite references in a text and
b) how to structure the references listed at the end of a text.
The Harvard System

The author and the year of publication of the cited document are given in the text.
If the author's name occurs naturally in the text then the year follows in brackets, if not, then both name and year are in brackets.

* Example

A study by Gremillion and Jenking (1981) showed that colour significantly improved recall ability. However, we need to guard against using distracting colours in order to realise these benefits (Marcus, Cowan and Smith, 1989).


CREATING BIBLIOGRAPHIC REFERENCES

Part 1: Non-electronic sources

Book References
 
What is needed? Author/s or Editor/s surname, initials.
(Year of publication).
Title of book (in italics, or underlined or in bold type).
Edition (if other than first).
Place of publication: Publisher.
* Example

Sommerville, I. (1992). Software engineering. 4th ed. Reading, MA: Addison-Wesley.

If there are two or three authors then all should be given, but if there are more than three then only the first is given followed by et al. or and others. If the book has an editor then ed. is added after the name.

* Example

Warren, D.H.D. and Szeredi, P. eds. (1990). Logic programming. London: MIT Press.

You may wish to refer to a chapter in a book. In this case the editor of the book is also acknowledged. In effect a double reference is required, with the more specific reference coming first.

* Example

Smith, C. (1980). Problems of information studies in history. In: S. Stone, ed. Humanities information research. Sheffield: CRUS, 1980, pp.27-30.

Notice that when referring to specific pages in a book 'pp.' is used. Use 'p.' if referring to a single page.

For books without individual authors use the corporate author if possible, otherwise use the title.

* Examples

British Computer Society (1991). Glossary of computing terms : an introduction. London: Pitman.
Turbo Assembler: users' guide - version 2.0 (1991). Scotts Valley, CA: Borland.

Journal Articles
 
What is needed? Author/s or Editor/s surname, initials.
(Year of publication).
Title of article.
Title of journal (in italics, or underlined or in bold type), 
Volume number, (Part number), 
Page number/s of the article.

The title of the journal should be in bold or italic type or underlined to distinguish it from the rest of the reference. There is no need to put in the words 'vol' or 'part'. The inclusive page numbers for the article should be given. If an article is interrupted by advertisements or other features this should be indicated by showing all the page sequences.

* Example

Nicolle, L. (1990). Data protection: laying down the law. Management Computing, 13(12), 48-49, 52.

Papers from Conferences

If the conference is one of a series use a similar method to that for journals but including the publisher if known, otherwise use the same method as for books.

* Examples

Feldman, D.S. (1993). Fuzzy network synthesis with genetic algorithms. Proceedings of the fifth international conference on genetic algorithms.

Urbana-Champaign, IL., July 1993. San Mateo, CA: Morgan Kaufmann, pp.312-317.

Duchastel, P.C. (1992). Integrating hypermedia into intelligent tutoring. In: A. Oliveira, ed. Hypermedia courseware: structures of communication and intelligent help: proceedings of a NATO Advanced Research Workshop. Espinho, Portugal, April 1990. Berlin: Springer-Verlag, pp. 198-204.

Theses

Use similar methods to those for books.

* Example

Levine, D. (1993). A parallel genetic algorithm for the set partitioning problem. Ph.D. thesis, Illinois Institute of Technology.

Reports

Similar method to that for books. Add all report numbers that appear on the document, plus publisher or distributor details if known.

* Example

Koza, J.R. (1990). Genetic programming: a paradigm for genetically breeding populations of computer programs to solve problems. Technical Report No. STAN-CS-90-1314, Computer Science Department, Stanford University.

Patents
 
What is needed? Inventor/s
(Year). Assignee
Title
Patent number
*Example

Graham, C.P., Fonti, L. and Martinez, A.M. (1972). American Sugar Co. Tableting sugar and compositions containing it. U.S. Pat. 3,642,535

British Standards

*Example

British Standards Institution (1981). BS 5930: 1981. Code of practice for site investigations.

Personal Communication

Can be used when one has cited unpublished information gained from a private letter, conversation or interview.

*Example

Ross, D.E. (1991). Personal communication



Part 2: Electronic Sources

No standard method for citing electronic sources of information has yet been agreed on.
The following citation formats outline the practices most likely to be adopted and are based on the book by Xia Li & Nancy B. Crane (1995) and the draft of ISO standard 690-2.

References to electronic sources follow the same general pattern as for non-electronic sources. Items from the Internet also use the URL (Internet address). The URL should only be split after a forward slash, no further punctuation should be added, and the case of the characters must not be altered. The examples given use the Harvard System, however these basic rules may be customised for any standard citation style.

Individual works
 
What is needed? Author/s or editor/s.
(Year).
Title [online].
Edition.
Place of publication: Publisher (if ascertainable).
Available at: URL
[Accessed Date].
* Example

Holland, M. (1996). Harvard system [online]. Poole: Bournemouth University. Available from: http://bournemouth.ac.uk/service-depts/lis/ LIS_Pub/harvardsyst.html [Accessed 15 April 1996].

The term [online] indicates type of medium and is used for all Internet sources. [Accessed Date] is the date on which the document was viewed. This allows for any subsequent modifications to the document. When referring to Internet sources the term publisher usually applies to the organisation responsible for hosting the site, such as Bournemouth University.

If no specific author is cited ascribe authorship to the smallest organisational unit.

* Example

NRSWG (2000). In the mail: report of a survey of interlibrary loan delivery [online]. Canberra, Australia: National Resource Sharing Working Group Available at: http://www.nla.gov.au/initiatives/nrswg/mailsurvey.html [Accessed 8 March 2000].

E-Journal Articles
 
What is needed? Author/s

Mailbase/Listserv email lists

These discussion lists generate email messages which are sent directly to the subscriber. References to these messages should be treated in a similar fashion to journal references; using the list name in place of the journal title and the subject line of the message in place of the article title. For "Available at:", use the email address of the list administrator.

These details, together with the author, will appear in the message header.
 
What is needed? Author (Year).
Subject of message.
Discussion List [online].
Day Month Year.
Available at: list e-mail address
[Accessed Date].
*Example

Brack, E.V. (1995). Re: Computing short courses. Lis-link [online]. 2 May 1995. Available at: mailbase@mailbase.ac.uk [Accessed 17 Apr 1996].
