Hello
improving the management of ISBN would be a nice enhancement.
This could improve search, and detection of duplicates.
I have never used Z3950 search, but if it is always translating 13
digits isbn into 10 digits, it is probably not a good. It should search
both forms.
Or search 3 forms in some cases : remember 13 digits isbn are not only
made with 978 prefix, but also 979. So, from a 10 digits isbn you can
made two 13 digits isbn.
For the way you must store isbn in the record :
In France, with UNIMARC and french cataloguing standard, we work like
this :
010 $aISBN10 (WITH the hyphens)
and we add an other 010, ONLY if the two are printed on the book, or if
the book were printed with isbn10 and reprinted some years later with
isbn13.
010 $aISBN13 (WITH the hyphens)
With AACR2 and Marc21, OCLC is also repeating the 020
https://www.oclc.org/bibformats/en/0xx/020.html
But rather than populating automaticly the record with alternates
versions of ISBN - that would be against our cataloguing rules - I would
prefer a change in Search.pm, so that when a search is made on isbn
index, Koha would search alternates versions of the isbn.
For an isbn10 : search isbn10 OR 978-isbn10 (with correction of control
element) OR 979-isbn10 (with correction of control element)
For an isbn13 : search isbn13 OR isbn 10
This could be done for isbn index, but also for any index if the string
searched by a user is an isbn.

Please consider the following scenario:
I have a book in my hands that bears ISBN-13 9780553507065, and wish to make
a biblio entry in koha. I go to Home > Cataloging and perform a "Cataloging
search" i.e. "Search the catalog and the reservoir" with the ISBN on the
book. Failing to find it, I then perform a Z39.50 search, select a fitting
entry and try to import it in my koha, only to find that the book already
exists there. Odd...
Correct me if I'm wrong, but koha staff client cataloging search at
/cgi-bin/koha/cataloguing/addbooks.pl seems to look for specific strings of
characters.
Therefore, when one enters an ISBN number of 9780006483113 as a search
string for example, koha fails to find entries bearing ISBN numbers of
978-0-553-50706-5
0-553-50706-0
0553507060
i.e. the alternate forms of the same ISMB number.
I also remember reading here in the list, that when performing Z39.50
searches koha first "translates" the ISBN-13 user input to ISBN-10 before
querying Z39.50 targets.
Thus, should one select a Z39.50 result with ISBN-10 and fail to "correct"
it before saving the new entry, is prone to the problem described above.
Furthermore, should that be the case, if one chooses to use the ISBN-13 form
only when editing his own entries, they would fail to appear on other
people's searches on his own koha installation, if their own system was koha
too (or preformed along similar lines).
Questions:
If one wishes to enter all four alternate forms of the same ISBN, is it
better to use multiple 020a entries (in USMARC) or to use multiple
occurrences within the same 020a entry?
Do other libraries/systems use the notion "A | B | C | D" I see in their
Z39.50 results, or is it simply a convention used to display in one line
values kept as discrete entries in the originating system?
Suggestion:
I guess there is some valid reasoning behind the behaviour described above,
resolved when these koha modules were created, I wonder however if it would
be useful that koha would automatically populate the bibliographical entries
with the missing alternate 020a entries (in USMARC), either at the time of
user input, or by some batch procedure, that would also take care of
existing entries. This could well be controlled by two new
options/preferences, one that would enable such behaviour and one that would
instruct koha to use one 020a entry to keep all four forms, or four discrete
entries.
