CILIP? Cilip? cilip?

CILIP vs Cilip...traditionally, an acronym (initials to make a word - e.g. scuba, radar, modem) doesn't need to use capitals but an abbreviation (initials that are spoken as initials - e.g. DfES, PDF) is written using capitals. Now, I have always written CILIP in capitals but I think that I might be wrong here...it's actually an acronym and as a proper noun, needs an initial captial letter, giving us...Cilip. I also see that that is what they use themselves.

I guess I had better update the title of my blog!
