The most simple way to find journal articles is to use Library Search, which covers many of the Library's journal databases simultaneously.
The alternative is to search an individual journal database. These will search a smaller number of articles than Library Search, but give you more control over your searches and more focussed results. Journal databases are particularly recommended for researchers and students doing dissertation research.
The key databases are Web of Science Core Collection and Scopus. They are both large databases that cover many subjects in the sciences, social sciences and humanities. I advise that you try both to see which gives the best results for your topic.
PsycINFO is the main psychology database and may be important for topics in human resource management and organisational behaviour. Please also consider the other databases under 'Other Useful Databases'.
A number of organisations provide quality rankings for journals in business, management and related fields.
One of the most well used rankings in the UK is the Academic Journal Guide 2015, provided by the Chartered Association of Business Schools (CABS). Journals are categorised by subject and ranked by quality, where 4* is the highest quality and 1 is lowest. You must register to view this list.
Professor Anne-Wil Harzing regularly compiles the Journal Quality List, which brings together rankings from a number of organisations including the CABS - for the CABS ranking, see the column headed ' ABS 2015'. The list is available arranged by title or subject,and is downloadable in PDF format.
A correctly formatted reference will tell you exactly where to find the full article:
