In my bibliography, I want to link the ISBN number to an actual website. My question is: which website is recommended to be used? Is there some 'neutral' source that I can expect to be still functioning in 5 years and that will return reliable results?
IBSN numbers are apparently provided by the International ISBN Agency, so this would clearly be the best source. Turns out, however, that they do not offer an ISBN lookup! I am currently considering two options:
Both appear to have their commercial interest, but they appear to be reliable enough. I would prefer Google. Or is there any other more recommended website?
