  In this paper we complete a classification of finite linear spaces $\cS$ with
line size at most 12 admitting a line-transitive point-imprimitive subgroup of
automorphisms. The examples are the Desarguesian projective planes of orders
$4,7, 9$ and 11, two designs on 91 points with line size 6, and 467 designs on
729 points with line size 8.
