This guide provides information on data discovery, citation, copyright and analysis.

Many research projects require secondary data in order to address a proposed research problem, hypothesis or set of objectives.

In addition, the quantity of data, their qualities and how they are sampled and measured, has implications for the choice and effectiveness of the data analysis techniques used in subsequent analysis. Therefore, it is important that you use the correct data for your research.

Finding data for re-use

Data are increasingly available in open data archives. is a global registry of research data repositories across all academic disciplines.

However, some data are only available through subscribed databases. You can view our , and also the for finding data within those subscribed databases and other sources.
 is also a useful source for finding datasets as you can use its . This is also a useful way to find data sets in the UCL Research Data Respository.

Your will be able to advise you of relevant data sources in your subject area.

Finding publications

Use Explore, as part of your literature review, to search for research studies based on secondary analysis of publicly available datasets. Books on your topic may cite relevant data providers, or volumes with statistical tables may identify sources of data.

Library Services also provides access to a wide range of bibliographic for finding journal articles and a range of other material. Your will be able to advise you of relevant databases.

Finding projects & UCL researchers' profiles

, the research portal for UCL, can help you to identify the research activities of researchers, research groups, research centres and interdisciplinary networks across the whole of the institution. You can search for researchers, publications, activities, groups, themes and departments.

Citing data

Data are legitimate, citeable products of research, just as other research outputs, so you must cite data.

• A Digital Object Identifier (DOI) is often included in data citations. This ensures that even if the location of the data changes, the DOI will always link to the data that were used. DCC guidance has further information on citing physical data (see below).
• Each dataset used must have a separate citation.

• If your department, discipline or publisher recommends a specific reference style, follow the appropriate form for citing data. For example:

  • The Harvard citation style uses the following format:

    Author names. Year. Title of resource. [medium type]. Host institution name, Physical location. Date of access. Identifier

    e.g. Institute for Social and Economic Research. 2011. Understanding Society: Wave 1 2009-2010 [data file]. University of Essex, Colchester, Essex. Accessed 29 May 2015. SN: 6614.

  • The Vancouver citation style uses the following format:

    Author names. Title of resource [medium type]. Host institution name: Physical location; Year of publication. [Date accessed]. Available from: Identifier

    e.g. Institute for Social and Economic Research. Understanding Society: Wave 1, 2009-2010 [data file]. University of Essex: Colchester, Essex; 2011. [cited 29 May 2015]. Available from: DOI:

Handling copyright & Intellectual Property Rights issues

Information is available to help you understand how to use copyright materials in your own work and in teaching. Useful background information is given, including explanations on Creative Commons licences.Ìý

If you have issues with Intellectual Property Rights, copyrights and licences for your own data, check our recommendations.

The gathers answers to a large range of questions on re-using data.

Analysing data

• UCL provides access to statistical software including: Excel, Matlab, R, SPSS and Stata.
• ISD offer a range of training, how to guides and assistance with statistical software.
• LinkedIn Learning has a number of video tutorials on these packages, while includes handbook, journal and reference content on secondary data analysis.
• Explore will allow you to find manuals on data analysis available from our libraries.

Commercialising research data

• Researchers are welcome to explore the commercial potential of their research outputs with a view to connecting with industry.
• UCL Business is the commercialisation arm of UCL and best placed to assist researchers in bringing to market innovations including research data.Ìý
• More information on commercialising research outputs is available.
