I was wondering if the members of the community would kindly share their wisdom in what is the best way to get BibTeX entries from ISBN number? I am currently using this service but results leave much to be desired for. Before I start writing a script which will fix all "imperfection" of the above service is there a better way to get BibTeX references from ISBN? In particular I am interested in web-sites which scale well because I would just like to get BibTeX reference of the web with the script and be done with it.
Did you try Lead2Amazon?
Sometimes you need to try other Amazon sites, e.g. when searching books of Herbert Voss ...
Search for ISBN and export to BibTeX
Search in all fields and export to BibTeX
All databases have many mistakes in the fields and you will have to doublecheck always. But dont worry the major science journals provide bad bibtex data too.
