I have prepared a paper using
LLNCS class and
splncs03 bibliography style. It seems the default behaviour of the style is to order references alphabetically. However, I need them to be listed based on their appearance order. Does anybody have a solution?
As Joseph Wright wrote, if alphabetic order is what Springer asks for, you should use it.
Having said that, you may get away with using an older version of their bibliography style, which you can find here: ftp://ftp.springer.de/pub/tex/latex/llncs/latex2e/splncs.bst
That one orders by appearance.
