Citations Source

[LIK MUI]

Hello,

I am new to the citation world.  Recently, I am trying to get access
to citation data for a computer science algorithm work, but have NOT
been able to locate such source.  (ISI wants to charge quite a bit
for it for their SCI.)

Could anyone point me to a free citation source covering any scientific
or engineering disciplines?  The data preferably have authorship and
and citation information for each reference.

Thanks very much in advance.
