Can PCR be used to nonspecifically applify cDNA's?

[IO00865 at MAINE.MAINE.EDU]

Is it possible to amplify cDNA's before cloning using nonspecific PCR?
What I have in mind is making double stranded cDNA using a standard
protocol and the blunt end ligating a specific linker to each end
of the DNA. PCR could then be performed using primers homologous to
the linkers. This would (hopefully) give you nonspecific amplification.

I think I've seen something like this in this newsgroup. Does anyone
have a protocol or a refrence? If not is this likely to work on theoretical
grounds or will you just get loads of short stuff amplified?
Thanks in advance
