This German dictionary contains over 280,000 references and offers comprehensive coverage of current German and English. Examples and phrases are provided to illustrate constructions and usage. A feature of this book is a 72-page section at the back of the book entitled "Language in Use", which is a grammar of communication in German and English, arranged thematically, to facilitate self-expression in the foreign language. Emphasis is placed on current German and English, with treatment of the basic vocabulary of each language, different meanings and context signposted throughout, style levels marked to provide advice and warnings to the non-native user, pronunciation in IPA, and full treatment of English phrasal verbs and US English coverage.
I have an old (1991) edition of this dictionary, from before the spelling reform.
Reading the introductory guide (especially the sections about indications and collocations) is important for understanding the structure of the entries.
The German-English dictionary that I've had since forever (well, since 1987, anyway). It's still useful, although I'm more likely to look for stuff at this site. and similar sites.
