Citations to data that is available in electronic format
should follow the guidelines for traditional formats,
appending at the end the following:
medium (e.g. Online (for Internet data), CD-ROM),
data supplier (e.g. IBM, MIT),
for Internet data the URL, for other data the filename,
the date you accessed the data.
It is generally preferable to cite traditional sources over Internet
pages as the latter tend to be rather volatile.
When you do cite material on the web, archive it using
