Might I suggest the Delaware Department of Transportation (DelDOT)
website.
Spicifically, their archaeology section.  It has a nice paper that
summarizes many results from historic flotation from 19th C. sites in
Delaware by William Sandy and the report from Block 1191 Wilmington.
Roger Moller did the floatation analyses for that report and there are
analyses from a variety of features.

Subject: float samples from 19th-cen refuse pit

On a recent excavation in SW Ohio, we took 5-gallon bulk samples from a 
19th-cen. Anglo-American refuse pit.  We have the opportunity to float
one or 
more of these samples.  Can the HISTARCH community offer references or 
articles concerning the results and intrepretations of
faunal/botantical/artifact 
recovery from float samples from similar contexts?  

Best,
