Correct way to cite paper that is published as part of a book I'm working on the last parts of my diploma in computer engineering. Right now i'm working over my bibliography. And i'm not quite sure what's the best way to include a citation.

Both refer to the same paper, the first one is a lot more detailed but it's not possible to view the whole paper online, since a few pages are being left out. 
The second one only refers to the paper, not including any publisher etc.

@inproceedings{booth2009,
author = {Booth, Danielle and Jansen, Bernard J},
booktitle = {Handbook of Research on Web Log Analysis},
title = {A Review of Methodologies for Analyzing Websites},
year = {2009},
pages = {143-164},
publisher = {IGI Global},
doi = {10.4018/978-1-59904-974-8}
}


or

@article{booth2009,
title={A Review of Methodologies for Analyzing Websites},
author={Booth, Danielle and Jansen, Bernard J},
year={2009}
}


Which one should I use?
The references are there for your readers to be able to hunt down the reference, be it to check what you say or to follow a different thread of research. For their sake, do find out as complete bibliographic data as you can, and add them to the citation.
