Danish : an elementary grammar and reader
Elias Bredsdorff (1999)
Long-standing reference grammar that could also be used as an introduction to reading Danish.
Clear and easy to follow :- includes an extensive 'phonetics' section to help with pronunciation and intonation of the spoken language.
A good hand-book for anyone wishing to revise particular parts of grammar or could be worked through as a course.
