The UK Data Service is the UK’s largest collection of digital social research data. They run a series of free webinars which cover an introduction to the service, international macrodata, secondary data, data management and more. There is also “Data Sources for Research Students” which may be useful for new PhD students.
Full details and dates are on their PDF: http://ukdataservice.ac.uk/media/455511/corewebinars2015.pdf
We have an introductory library guide to the UK data service (PDF) and subject librarians would be glad to provide further support using the service if required.
