I tend to disagree, I'm afraid.  If the problem is that surplus  
information is *imported* (as after an external database query),  
then the correct way to deal with this problem is to restrict  
the flow of information across the import reader.

1. For »tagged« readers, as MEDLINE, it is simple to exclude  
some »tags« from import processing.  As tagged readers are the  
most important class a.t.m. this should prove worthwhile to  
implement.

2. Another quite useful and versatile customisation technique is  
to call appropiate *user-exits*, say  (pending  systematic  
naming ;-)),  for every import record
	from Pyblio import userexit
	x = userexit.post_medline_import_record (entry)
	if x: #accept (modified) record
	else: # ignore record

The latter is in addition quite simple to implement, so it will  
be done for 1.2.7, while I'm not sure whether the first option  
can be realised in time for the samme release.

Reagrds,
