German-English Dictionary
I am looking for a good German dictionary. There are three types I would like to have referred to me particularly.
1. A dictionary that is very comprehensive and contains some scientific words(an equivalent of a college dictionary if that helps)
2. A dictionary that is meant for younger children and does still contain a lot of larger more specific words but lacks the scientific words
3. Though the above would be nice with an English translation to it, I would like to make a separate section for that. So please also recommend a good German-English/English-German dictionary as well if you can.
Thank you for your time.
