As a researcher or student, in many cases you can't rely on academic literature solely. Below three important databases are highlighted. Patents that describe certain technologies can be a valuable source of information in engineering projects. Norms and standards that apply to geographical regions have to be taken into account for innovations to succeed in the real world. Indexed news, business and legal sources can put the topics researchers and students are working on in a different perspective, leading to new ideas or collaborations. For an overview of databases with academic and non-academic literature, consult Databases A-Z. For an overview of databases per subject field go to Guides per discipline.
