Invitrogen sells cDNA libraries (supposedly full length, checked a
couple of 5' ends - were fine) in SV40-ori containing vector. This
should work in Cos cells if you do not plan LONG (>6 d) selection.
Otherwise, run-away replication of plasmids will kill the cell.
Stratagene - as far as I recall - has libraries in a vector with EBV
ori-P, which should not have these problems. However, you should find
a cell line which expresses EBNA to support the replicastion
(actually, if you DO find such human cells, I will appreciate a
pointer).
Several other companies were rumored to have similar libraries.
No affiliation with any of the above....
Good luck,
