The NBI Library

The library at Blegdamsvej 17 offers help and information to students, researchers and guests at the Niels Bohr Institute in order to promote learning, research and education at the institute. Our study spaces are available to students and staff 24 hours.













The material on this page are textbooks / teaching notes written mainly by educators at the H. C. Ørsted Institute (the current Niels Bohr Institute) during the period from 1985.

The texts are written in Danish or in English and are made available by the rights holders so that anyone who wishes may read them. All texts that existed only in print are scanned and made searchable via electronic text recognition (OCR). The selection of notes was done in collaboration between Jens Paaske (NBI) and Martin Skogstad (Frederiksborg Gymnasium), while the scanning was done by the latter.
