Databases organize and structure information with the aim of facilitating its retrieval, usually by author, keywords, subjects, etc. Use databases when you want to find up-to-date and specialized information on a topic.

Unlike library catalogs, databases are usually commercial products in which an editor decides which topic they will deal with and which information they will collect on this topic. There are, however, many databases created by professional or scientific institutions that allow free access to the information collected.

Each database has its own content and focus, so you have to choose the most relevant according to your need:

  • of a more practical or more theoretical nature
  • international, European, state or local
  • with a certain focus: mathematician, social...
  • within a certain time limit
  • of a specific type of document

The libraries of the UPC they give you access to more than 150 databases from different fields. Some are free and others, the subscription ones, can be consulted inside and outside the UPC through the service eBIB. Find them at:


List of subscribed or free electronic resources of the libraries of the UPC.


It is important that before starting to search, consult the manual of each database to know its search options: booleans, truncations, indexes, etc.

Search engines are tools to retrieve information available on the Internet (ex. Google). Use them to retrieve:

  • Very precise information (data of people, relevant organizations or product characteristics, etc.)
  • Specific documents of entities or official associations, news of interest or websites of recent appearance, etc.

Academic search engines make it possible to retrieve quality scientific and specialized publications. These search engines find information from reliable sources such as scientific publishers, academic repositories, specialized blogs, academic social networks, etc. Some examples are:


Since the launch of ChatGPT in late 2022, a multitude of artificial intelligence chatbots based on extensive language models have emerged (LLM - Large Language Models) and machine learning systems (machine learning) or deep learning (deep learning). These conversational chats make it easy to find information because they understand natural language and are easy to query. We must understand, however, that these generated texts are based on huge amounts of previous texts or images and what they offer us may not have any relation to reality; their answers are created from the information you provide them in the search questions (prompts). You must be extremely careful when using these tools both in the personal and academic environment and always check the information obtained with reliable sources. Today some of the most used chatbots are:
