I’m writing a report and I had to cite an article from a book. It’s one of this book which every article can also be used as a standalone paper. The problem is that if you use an article record, you will miss the book and if you use the book record, you will miss the article.

How to solve it? Google it! (somebody has already solved it and post it somewhere)

And it is. The solution is to use @incollection:

author = {John Doe},
title = {Dynamic Ambient Paradigms},
booktitle = {Paradigm Gems 2},
pages = {223--233},
publisher = {Addison Wesley},
year = 2005,
editor = {Averell Doe}

More BiBTeX tips (where I found this solution) on this page.
