In fact the MARC view in the staff client and the OPAC do not show the 
correct content (as foudn in the database) of any field, if mor than one 
blnak does appear fllowing each other - instead the they will be 
automatically collapsed down by the webbrowser to just one. Even the 
MARC plain view in the OPAC behaves in this wrong way; and only (but 
most importantly) the actual catalogueing framework behaves correctly.

So the OPAC view etc will show something like the following, which 
according to the MARC 21 format can never be correct because MARC 008 
MUST contain 40 characters, but the OPAC view does only show 31 in this 
case:

190315b ||||| |||| 00| 0 ger d

However, of course I hope the Batch record modification will work on the 
actual data in the database which of course actually does contain 
exactly 40 characters: (I kept the tags to show where the data actually 
begins and ends, since blanks are hardly visible)

<controlfield tag="008">800422s1978    sz        a     1   ger 
</controlfield>

No, I have counted them before, my regular expression looks like

m/^...................................ger..$/

According to the MARC 21 Format for Bibliographic Data controlfield 008 
contains 40 positions. In my regular expression

* positions 0-34 can contain any character (thus 35 dots)

* positions 35-37 must contain "ger" (thus the three characters "ger")

* positions 38-39 can contain any character (thus 2 dots).

All in all my expressions does contain 40 positions. So I guess it 
should work, but it doesn't. Is this maybe a bug?

Best wishes: Michael
