Data Search Support

Data search support for Maastricht University students and staff members

1.General info #

Governments, NGOs, academic institutions and private companies all collect data. Many datasets are available for re-use in your research. However, it is not always straightforward to find these datasets.

The data search module provides general information on how and where to search for datasets. Should your data search question not be solved by the module or the FAQ, please contact the library via Ask-Your-Librarian. We can assist you in optimising your data search strategy and/or contact a data supplier on your behalf.

Note that when re-using research data, you must comply with the rules and regulations governing data copyright, intellectual property rights, and laws governing sensitive or personal information. SURF has compiled a report on the legal status of raw data, including information on the types of consent required for the re-use of data.

3. FAQs – Check before you contact the support team #

Can I get assistance in analysing data?

Unfortunately, we cannot offer specific data analysis support. For questions about data analysis, your best option is to contact a statistics professor or tutor from your own faculty. In addition, there is always the possibility to use a free online course or instruction videos on YouTube.

How can I combine data sets?

There is nothing more efficient than being able to use the output of one database as the direct input for the second database.

The moment you retrieve company data from your first database, please make sure you collect as many identifiers (tickers, CUSIP, SEDOL etc.) for these companies as possible. This will save you a tremendous amount of work the moment you need additional data form a second database.

What type of data is available in what database?

There are far too many databases to give an exhaustive overview here.

You will need to look at the information (e.g. online manuals) provided for the individual databases. Alternatively, research papers related to your topic should help you identify databases that may contain the type of data you need.

Can I get a trial subscription for a database?

Unfortunately, it is not possible to obtain a trial subscription for any databases. For each year, the faculties and the library set a budget and carefully select which database licenses this budget is spend on. Although you could contact your faculty library committee to suggest trialing a particular database, this process is lengthy and not likely to lead to database access within the time period of a bachelor or master project.

The data I need is nowhere to be found in the university databases. What now?

It is strongly advised to check the availability of data before you start your research and writing process.

If the data is not available in our databases, it may be available from a repository. Repository data can be found by searching the repository or by using a dedicated data search engine, such as Mendeley Data Search or Google Dataset Search, to search across a variety of repositories. Re3data is a global registry of research data repositories and can be used to identify potentially relevant repositories. For more information on how to search for datasets, see the data search module.

Alternatively, you could try to source the data you need through your network. Personal or department subscriptions to databases are not uncommon. Your supervisor or colleagues may be able to help you out.

Can I use Google Dataset Search?

Google Dataset Search can help you find datasets wherever they are hosted online, whether it is a publisher’s site, a digital library, or an author’s personal web page. It works like other Google tools, such as Google Scholar, which means it has the same pros and cons. Alternative tools, such as Mendeley Data Search and Re3data are alternative tools which offer more options for systematic dataset searching.

I need help with my searching/writing process. Who can help me?

Depending on the type of help you need, there are two options: PeerPoint or Ask Your Librarian (AYL).

  • AYL is our general helpdesk and is particularly useful if you have a specific question regarding a database.
  • Peerpoint is a free peer-to-peer service and offers more extensive support. Specialised master students working for Peerpoint can aid you with your research process, your search skills, and your academic writing. Please visit the PeerPoint-page to get in contact with them.
