The only information you will usually need when citing within the text is the author’s surname and the year of publication. See examples below
Please also note:
For sources where the format of the citation is more complex, examples are provided within the MMU Harvard section of this guide.

To distinguish between different sources by the same author published in the same year, use a, b, c etc. after the year in both the citation and the reference. The letter you assign to the publication should be in order of its appearance in the main text of your work. Therefore, the first publication you cite should be assigned the letter ‘a’, the next citation will be ‘b’ etc., regardless of the month in which it was published.
(Cottrell, 2012a) - for the first instance of a citation by a Cottrell published in 2012
(Cottrell, 2012b) - for the second instance of a citation by a Cottrell published in 2012
You should then also use the letter for the full details of the source in the reference list.

If you are citing a number of sources that support your argument, you would cite these in chronological order, separated by a semi-colon e.g. (Beck, 2012; Shields, 2013; Inala, 2014)
For different authors who have published in the same year, cite these in alphabetical order e.g. (Beck, 2014; Inala, 2014)
