Linguist William Poser in Language Log has criticized some of Cavalli-Sforza's comments about linguistics, in particular the suggestion, echoing controversial linguists Merritt Ruhlen and Joseph Greenberg, that some mainstream linguists are unnecessarily conservative about hypothesized long-range relationships between language families, and an overstatement that Greenberg's critics " have ruled out the possibility of hierarchical classification ", which Cavalli-Sforza did not defend when challenged by Poser, but deferred to Ruhlen.

Collation differs from classification in that classification is concerned with arranging information into logical categories, while collation is concerned with the ordering of items of information, usually based on the form of their identifiers.

The British Government codified this, to some extent, with the publication of the Official Secrets Act in 1889 and by the time of the First World War multi-tier classification systems were used to communicate information to and from various fronts.

The volume of information shared by the Allied countries during the Second World War necessitated formal alignment of classification systems and procedural controls.

This requires information to be assigned a security classification.

Some factors that influence which classification information should be assigned include how much value that information has to the organization, how old the information is and whether or not the information has become obsolete.

The type of information security classification labels selected and used will depend on the nature of the organisation, with examples being:
