7. aggregation with independent works

a compilation of the document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, does not as a whole count as a modified version of the document, provided no compilation copyright is claimed for the compilation. such a compilation is called an "aggregate", and this license does not apply to the other self-contained works thus compiled with the document, on account of their being thus compiled, if they are not themselves derivative works of the document.

if the cover text requirement of section 3 is applicable to these copies of the document, then if the document is less than one quarter of the entire aggregate, the document's cover texts may be placed on covers that surround only the document within the aggregate. otherwise they must appear on covers around the whole aggregate.
