Sources to get started

Web sites

They allow simple, fast and immediate access to information, even if they do not offer answers to everything and it is necessary to verify the authoritativeness and reliability of the contents.

Not all sites are free to access and the sponsored ones may contain biased information, as we will see later.

If, on the other hand, you need to frame a topic of which you have in-depth knowledge, you can consult:

• databases
• specialized books
• Scientific magazines
• doctoral and graduate theses
