When you're referencing with Leeds Harvard you may come across issues with missing details, multiple authors, edited books, references to another author's work or online items, to name a few. Here are some tips on how to deal with some common issues when using Leeds Harvard.
Skip straight to the issue that affects you:
- Online items
- URL web addresses
- Multiple authors
- Corporate author(s)
- Multiple publisher details
- Missing details
- Multiple sources with different authors
- Sources written by the same author in the same year
- Sources with the same author in different years
- Two authors with the same surname in the same year
- The work of one author referred to by another
You should reference the actual version of the item that you have read. This is especially important for items which are published both online and in print/paper format, as page numbers and other information may be different.
These three pieces of information should be included whenever you reference something you read online, no matter what type of document it is:
- the URL
- the date you accessed the article.
Example for an online journal article:
El Gharras, H. 2009. Polyphenols: food sources, properties and applications - a review. International Journal of Food Science & Technology. [Online]. 44(12), pp.2512-2518. [Accessed 10 June 2016]. Available from: http://onlinelibrary.wiley.com
If you download or read a PDF from a website, you must reference the actual document type, for example a book chapter, a government report or a leaflet, not the file format (PDF).
URL web addresses
Some online journal articles and webpages have very long URLs. The Library recommends that you only put the URL as far as the first forward slash /.
For example: Available from: http://0-web.ebscohost.com.wam.leeds.ac.uk/
Rather than: Available from: http://0-web.ebscohost.com.wam.leeds.ac.uk/bsi/detail?vid=4&hid=7&sid=27735707-0bdb-468e-a7a6-47ea3c7c036c@sessionmgr7&bdata=JnNpdGU9YnNpLWxpdmU=#db=buh&AN=3891036
Ensure that you are using the URL (web address) of the actual source document, and not the URL of the search result in Search@Library or other search engine. URLs from Search@Library have the words "summon.serialssolutions" in them.
If you are using a reference manager such as EndNote or Mendeley, it is important to check the URL on items you have imported from databases or search engines, and amend it to the URL of the source document (rather than the database or search engine) where necessary.
You should include all author names in the reference. Where a source has a very long list of authors, e.g. in the case of some scientific articles, you might wish to consult your tutor on whether to use "et al." in place of some author names.
If the source has two authors, you should include both authors in the reference, with their names separated by "and".
Format your reference as Family name, INITIAL(S). and Family name, INITIAL(S). Year. Title. Edition (if not first edition). Place of publication: Publisher.
Ahmed, T. and Meehan, N. 2012. Advanced reservoir management and engineering. 2nd ed. Amsterdam: Gulf Professional Publishing.
In the citation, both names should be given.
It was emphasised that citations in a text should be consistent (Ahmed and Meehan, 2012).
If you have already named the authors in the text, only the year needs to be included in brackets.
Ahmed and Meehan (2012) emphasised that citations in a text should be consistent.
Three or more authors
If the source has three or more authors, you should include "and" before the final author name.
Format your reference as: Family name, INITIAL(S)., Family name, INITIAL(S). and Family name, INITIAL(S). Year. Title. Edition (if not first edition). Place of publication: Publisher.
Clayden, J., Greeves, N. and Warren, S. 2012. Organic chemistry. 2nd ed. Oxford: Oxford University Press.
In the citation, if a source has three or more authors, the name of the first author should be given, followed by the phrase “et al.”
- It was emphasised that citations in a text should be consistent (Jones et al., 2011).
- Jones et al. (2011) emphasised that citations in a text should be consistent.
If you are referencing a book with an editor rather than an author, this should be indicated in the reference.
Family name, INITIAL(S) (of editor). ed. Year. Title. Edition (only if not first edition). Place of publication: Publisher.
Crandell, K.A. ed. 1999. The evolution of HIV. Baltimore: Johns Hopkins Press.
Wexler, P., van der Kolk, J., Mohapatra, A. and Agarwal, R. eds. 2012. Chemicals, environment, health: a global management perspective. Boca Raton, FL: CRC.
For an edited book with chapters written by different authors, see Book chapter (in an edited book).
If the item is produced by an organisation, then you should treat the organisation as a "corporate author".
This means you can use the name of the organisation instead of an individual author. This could include government departments, universities and companies. Just use them in the citation and reference in the same way as you would an individual author.
When the corporate author name is not mentioned in your text, the citation consists of the author name and the date of publication in brackets, often at the end of the sentence:
According to a recent report, flu jabs are as important as travel vaccines (Department of Health, 2011).
If you have already named the author in your text, only the year needs to be included in brackets.
According to the Department of Health (2011), flu jabs are as important as travel vaccines.

If multiple publishers are listed, you should include only the first publisher listed, or the British one if it is a choice between a UK and an overseas publisher, in your reference list or bibliography.
Multiple places of publication
If multiple places of publication are listed, you should use the first place name given when writing your reference list.
If there is a town and county/state on the title page, you should just give the town. However, if there is more than one well-known town of that name you might want to give the state as well to make it clear.

No page numbers
Page numbers are only included in your reference list or bibliography for a few types of reference, eg journal articles, newspapers, chapters in edited books. If the source has no page numbers, use [no pagination].
Pajunen, K. 2008. Institutions and inflows of foreign direct investment: a fuzzy-set analysis. Journal of International Business Studies. 39(4), [no pagination].
In the citation, use (no pagination).

If you are citing specific information from a website that does not have page numbers, you do not need to include anything to indicate this in the in-text citation.
No publisher or place of publication
If you are unable to identify the publisher or the place of publication, use [no publisher] or [no place], as appropriate.
Multiple sources with different authors
If you need to refer to two or more sources at the same time, these can be listed, separated by semicolons (;). The sources should be ordered by year of publication with the oldest first.
It was emphasised that citations in a text should be consistent (Smith et al., 1998; Roberts, 2005).
If more than one item was published in the same year, they should be listed alphabetically by author surname.
It was emphasised that citations in a text should be consistent (Andrews et al., 1998; Jones and Baker, 1998; Salmon, 2001).
Sources written in the same year by the same author(s)
If two or more sources have the same author(s) and are from the same year, they should be distinguished by adding a lower-case letter after the year (a, b, c, etc.).
It was emphasised that citations in a text should be consistent (Jones, 1998a). In a work published later that year, Jones (1998b) proposed that...
If you want to make a single reference to multiple sources from the same year by the same author, you can cite the sources together using the lower-case letters.
It was emphasised that citations in a text should be consistent (Jones, 1998a; Jones, 1998b).
Each citation should have a matching reference in the reference list.

Sources written by the same author(s) in different years
If you need to refer to two or more sources by the same author in different years, there is no need to keep repeating the author's surname in the citation.
Include the surname and the oldest year first, then separate the other years by semicolons (;). The sources should be ordered by year of publication, with the oldest first.
(Smith, 2001; 2005; 2013)
You must include all of the sources separately in your reference list or bibliography.
Sources written by two authors with the same surname in the same year
If two or more sources have authors with the same surname and were written in the same year, they should be distinguished by including the authors' initials in the relevant citations.
It was emphasised that citations in a text should be consistent (R.F. Jones, 1998). In a work published later that year, C.B. Jones (1998) proposed that...
The work of one author referred to by another
You should always try to track down the original work, but if this is not possible and you intend to cite the ideas of one author that you have found in the work of another, your in-text citation must include the author of the ideas you are using, the source in which you found them, and the page number.
It was emphasised that citations in a text should be consistent (Jones, 1998, cited in Carol, 2001, p.9).
In your reference list or bibliography, you should only give the details of the source in which you found the ideas. In the above example, you would include the work by Carol, 2001.
If the reader wants to find the full reference details of the original work by Jones, they should be available in the list of references in Carol's work.
