The library offers us access to thousands of printed and digital resources in multiple languages: books, publications, articles, proceedings of conferences, market studies…

In order to find diverse materials on a subject of investigation, it is important to be familiar with some of the main sources of information (catalogues, databases, electronic summaries…).



The catalogue is a tool that allows us to know everything the library has to offer. It includes physical resources like books, magazines, DVDs and CDs, among others. It also includes online resources: databases, electronic books, electronic publications, thesis papers, etc.

Databases let us know what has been published on a subject on a global level. They collect publications with scientific/technical content: academic articles, proceedings of conferences, reports, market studies, electronic books, etc.

It is important to know the difference between:

  • Referential databases, which only include document references, but not the documents themselves.
  • Full-text databases, which in addition to document references provide access to their full text (in PDF, HTML, etc.).

In terms of content, it is also important to consider the differences between:

  • Multidisciplinary databases, which include information covering multiple themes or subjects.
  • Thematic databases, which contain information on a certain area of research.

All scientific areas have either a specific database or are covered by a multidisciplinary database.

Search engines allow us to look for documents available on the Internet, but they generally do not take into account their veracity. In most cases, the results of searches are organized according to internal interests (publicity) or depending on search criteria (for example, first showing results that match the phrase being searched). Two examples of Internet search engines are Google and Bing.

There are certain academic search engines like Google Scholar or Microsoft Academic that allow you to locate information that is more trustworthy and contrasted.
