Linker add., PCR amplif., cloning, seq'ng -> degraded R.E. sites?

Mon Apr 1 11:28:55 EST 1996

After addition of linkers to blunted DNA followed by PCR amplification, 
cloning (via R.E. site in linkers), & sequencing, we've noticed some sequence 
anomalies in the R.E. cloning site (partial site on one end) as well as 
remnants of the entire linker on the end of the cloned fragments rather than 
just the residual?  Has anyone seen anomalies like this or suggest a published 
citation that helps explain similar sequence anomalies?  Very much appreciated.
