100 year ZFC, wrong year in bib file ?

[gunpinyo]

100 years of Zermelo’s axiom of choice: what was the problem with it?

The bibtex entry, said that it is published in 2006 but the pdf title said 2009. Which one is correct ?

Thank you,
Gun

Good catch. There seems to be two versions of this article:

• The one from 2006 in The Computer Journal (cf. the ACM Digital Library) listed in the bib file
• Another one from 2009 published by Springer

I don't know which version we should keep (if not both).
