How do I find information for my TFG / TFM

When it comes to developing a TFG it is essential to find the right existing bibliography about the topic of your work.


A good search strategy will allow you to successfully query the information retrieving tools to get relevant results. First, identify the keywords that represent the topic, and then use the corresponding elements to relate these terms (Boolean operators, proximity operators, truncation symbols, etc.).

This tutorial will help you formulate your search strategy correctly (in Catalan).



Library catalogs will be useful for a first approach to the topic of work.

DiscoveryUPC is the content search engine of the libraries of the UPC which will allow you to search from a single search box the contents of the Catalogue, the Digital Library and the institutional repository UPCommons.



These tutorials will help you browse DiscoveryUPC:


If you are interested in electronic books, this page will be useful for you. 

El Collective Catalog of the Universities of Catalonia (CCUC) will allow you to jointly search all the catalogs of the member institutions of the Consorci de Serveis Universitaris de Catalunya.

You can also search together in the catalogs of Spanish universities: Catalog of the Network of University Libraries (REBIUN).

The databases they will allow you to deepen the search for specialized bibliography. You will have to choose the most relevant one depending on your need. To find out which databases are available in the libraries of the UPC, you will have to consult DiscoveryUPC.

Please note that, if you wish to consult the electronic resources subscribed by the Libraries of the UPC, you will need to do this through the servei eBIB. This tutorial shows you how to use it.


The Internet offers access to many quality scientific information: academic search engines, themed portals, e-prints, etc.

Academic search engines work just like the general search engines. They are multidisciplinary and they usually incorporate free access sources of information. The most outstanding are:

e-prints deposits allow to consult, in open access, scientific documents generated by researchers. There are some who are thematic (ArXiv -mathematics, physics-, RePEc -economy-, etc.) and others that are institutional (generated by a university or entity).

At UPCommons, the Institutional Repository of the UPC, you will find the teaching and research production of the UPC: journal articles, congresses, academic works, etc.

Thematic guides allow you to consult a selection of resources of interest related to the subject of your work.


The Libraries UPC collects a set of thematic guides in the polytechnic field.


Evaluate the information resources used and the results you have obtained in your search. To do this, you should follow some criteria in order to assess whether the results you have obtained will be useful or not.
