"Information on something", "information of something", "information about something" — these three usages all sound having the same meaning for me. Are there any differences?
"On" has the meaning of 'covering' here, as in :
"Information on something" would be information that is really in-depth, and quite into details. i.e. A study on history, or A book on biomedicine.
"information about something" has the implication that it is information that is a kind of summary about a subject i.e. A brochure will contain "information about something", but you can't really say "A brochure on mechanics." You would use "A brochure about mechanics."
"information of something" used in this way basically means the same as "information about something", but I would using "information of something" for the reason that it could be misunderstood to mean "Information belonging to something".
It would be much better to use "information about something" in this case.
Hope that helps!
It might be a regional thing. I grew up in New Zealand, and for me "information on something" and "information about something" mean the same thing. "information of" means "information belonging to", although not in the strict legal sense of belonging. psmears gives a good example.
