A LIST OF PERTINENT NONTECHNICAL LITERATURE. 
As pointed out in the introductory portion of this bulletin, pres- 
ent-day canning technology has been determined in large measure by 
the recommendations from a voluminous semiscientific or nontech- 
nical literature. For the benefit of those investigators who may need 
to look into the matter in greater detail than has been possible in 
the present case, a list of the more important of these pertinent 
papers is given below. With the exception of a few widely read 
texts, the list is made up almost exclusively from the official publica- 
tions of Federal and State canning specialists. Similar papers, 
which merely quote from other writings, or whose authors assume no 
responsibility for the recommendations given, are omitted.
