As I pointed out in my recent posting, the data obtained this way are 
usually inferior to the original DELTA data. (For more details, see 
'Exporting DELTA-format data from Intkey', DELTA-L 7 November 2003 
(http://markmail.org/message/q3va2v2ze7twjcip.) So the reasons for doing 
it could be:

(1) To obtain the data without the knowledge and permission of the author.

(2) To obtain the data if the author has declined to supply the original 
data, or has placed unacceptable conditions on its use.

(3) To recover data when the original files have been lost.

I invite comments. Perhaps (1) is motivated by shyness or diffidence; or 
maybe it's just too much trouble to contact the author. In itself, it 
doesn't matter: the data are published so that they can be used. But 
consequences might be failure to cite the source of the data in resulting 
publications, or to publish an inadequate version of the data. That was 
what prompted me to write 'Guidelines for using data taken from Web 
(http://delta-intkey.com/www/data-from-web-publications.htm). See also my 
Taxacom posting 'Guidelines for using data taken from Web publications', 
16 January 2008 (http://markmail.org/message/xpmvt4qfcnjdigqd), which 
contains a more detailed description of some of the problems that may arise.

I didn't mention in my postings on this subject that there's a little-used 
Confor directive DISABLE DELTA OUTPUT. "This directive, used with 
and OUTPUT SUMMARY (which produce DELTA-format data). Note that this 
cannot prevent Intkey users from capturing data for processing by other 
programs - it only makes it more difficult." Also, it doesn't prevent 
other programs from capturing the data from the Intkey files.
