I have discussed this with some colleagues and we tend to
agree that using dc:source to point to a document from which a
concept is derived is a stretch.  Saying that a SKOS concept
derives from a book is a bit like saying that a word derives
from a dictionary.

The Definition of dc:source is: "A related resource from which
the described resource is derived" and the Comment reads:
"The described resource may be derived from the related
resource in whole or in part."  In practice, this has been
used to point to a "source" document from which a described
document has been derived -- for example, the print version
of a document from which a scanned version was produced.

In part because its meaning is difficult to pin down, the
use of dc:source has often been discouraged in favor of
properties that are more specific (or even more general,
like dc:relation).  I'm sure there are better properties to
use for this example.
