For multiple reasons are < or [ used in cataloging dates that are either unknown or with a range. These are three examples that do not work or get stored properly in Koha and the database. [19--] <1981-> [1981] Currently, if a publication year has the hard brackets or the hungry alligators with a year, the date does not get stored in the database as a value, but it stored as null. It would be nice if Koha were to display the year regardless of the < or [ . If a year is presented like this [19--], Koha should use the value of the year with 1900 in the database, and in a case such as this <1981->, it should be 1981. The database holds these values as NULL. When an item search in Koha is done with a record with one of these values, the publication year will display as 0, which is not helpful to a library when needing the publication date stored in the Marc Record.
Also we get some logs like : Argument "[s.d.]" isn't numeric in int at /home/koha/src/C4/Biblio.pm line 2832.
Hi Kelly, I think this is a duplicate to bug 24674 - which has a patch awaiting testing :) *** This bug has been marked as a duplicate of bug 24674 ***
