It is important that the reference points directly to the list of references. Every source that has been cited in the text is mentioned in the list of references and every source mentioned in the list of references should be cited in the text.
A reference management program facilitates keeping your references in order. University of Vaasa and Åbo Akademi University have licenses to RefWorks, but there are also free reference management programs and a built-in reference management function in Word. This guide presents some of these reference management tools.
To select the most appropriate reference management software, you need to consider what features you need. Do you want to be able to work with the references in Word? Do you want to be able to reach the references from different computers? Do you want to be able to work offline? In this table you find a comparison between different programs. In Wikipedia there is a more extensive list of comparisons between different reference tools.
