Where else am I looking? - Subject portals

And then there are special, subject-specific websites. These specialist portals contain a selected range of content, which is checked regularly.

What is the advantage of these subject portals?

• They contain scientifically relevant links.
• Experts compile the content, check it and comment on it.
• As a rule, the operators (e.g. authorities, scientific institutions, companies) have no economic interest in marketing their offerings.
• The offers limit their search thematically and qualitatively.

Therefore, they achieve more relevant results in a search query.
