Sorry if this sounds misleading  - I trusted in the release notes stating 
"New and updated sequence data from the latest GenBank and  DDBJ  releases
have been  incorporated  into  this release." Freeze date EMBL 
Release 33 on 8 November 1992, GENBANK 74 on 17 November 1992 - 
I thought that this would imply the most recent daily updates from 
GENBANK also to be in EMBL and vice versa.

I used the -exclude flag in the GCG software to compute the numbers that I 
quoted. The entry number is surprising to me also, and I just hope that 
there is an error in my procedures. 

With respect to the numbers; I have taken the daily EMBL updates (as of Dec 20
at EMBL creation), and the GENBANK 74 release files (not their daily updates), 
and came up with 8141 entries of EMBL, resembling 8540 accession numbers. 
(This is for both new entries from EMBL and GENBANK as sent by EMBL in 
EMBL format. If I look at how many entries are in GENBANK 74 not in 
EMBL 33 (containing 5698 AN), and subtract those which are unique to EMBL, it 
appears that EMBL updates contain 2591 entries which are in GENBANK 74 
(according to 2612 Accession Numbers). That still leaves us with a 
considerable number of discrepancies.

Your work is most appreciated, and I encourage you to keep up the good 
work. I didn't want to make any negative statements on quality in general, 
just point out that the exclusion sets are still a need.
