BibTex information for books?

If your are citing books and you are sick of creating the BibTex data for yourself: Cheer up, there is a easy way to get the data created. You just have to get the ISBN Number of the book (easiest by finding the book on wikipedia). Then you use the OttoBib webservice. Just replace the ISBN number in this example

http://www.ottobib.com/isbn/9780199535705/bibtex

Calling this URL gives you

@Book{marx2008capital,

title = {Capital : an abridged edition},
publisher = {Oxford University Press},
year = {2008},
address = {Oxford New York},
isbn = {9780199535705}
}

Easy and a real life saver….
