I don't know about the GENEBANK entry above but, unless I'm the one who 
missed something, pBS IS NOT pBlueScript, but pBlueScribe as Francis 
stated. pBlueScribe was an ancestor of BlueScript, with much of the same 
"phagemid" elements in it (perhaps exactly the same?), but fewer sites in 
the polylinker. I still use some of my "older" constructs made in pBS 
and, yes, it is always confusing between the two vectors with such 
similar names, but pBlueScript was never abreviated to pBS by Stratagene.
