ABOUT IT NOTES
The IT notes collection is intended for IT documents which have not been sent for publication, and are therefore of a more internal nature. They can record any aspect of IT infrastructure or services and need not be peer reviewed, but should be of some lasting value as a reference for other members of the depeartment or the wider CERN community.
