Hi there I'm trying tu get my Koha3 up and running, but need some directions setting Matching Rules to import MARC records. First of all ... Matching rules seems to be working ok ... I've used the ISBN rule and got good results.... BUT ... there are some problems when the records don't have ISBN data (or ISSN) ... so I need a way to match those. for example .. I have this record (already imported into Koha) and when I try to import again it has "no match" (of course, because it has no ISBN) LDR 00645nam#a2200253#a#4500 001 CON000008 003 OUN 005 20060601105400 008 901227| xxu |||| ||eng d 040 _aOUN 080 _a3-055.2 080 _a341.16:362.7 092 _sNU _c3-055.2 _lH431u 100 1 _aHazzard, Virginia. 245 10 _aUnicef and women : _bthe long voyage : a historical perspective 260 _aNew York : _bUnicef, _cc1987. 300 _a148 p. ; _c27 cm. 440 _aUnicef history series. _pMonograph ; _v7 650 04 _aUNICEF 650 04 _aMUJERES 866 0 _a1 ej. 907 _aTEXTO 930 _a90476 _dREST _pv 942 _cBK So ... I need advice on how to set up a valid matching rule to handle a situation like this one. The records will come from various libraries (around 13) each one with distinctive control numbers (field 001) so I think maybe comparing this field and title (field 245$a) would give me a good enough matching rule. the problem is ... how to set it up on Koha :) Frist thing I don't understand completely ... when creating a new matching rule I must specify a "search index" value (on ISBN rule it has 'isbn'). Now, for something like what I need, what should be the value, if it has to be one... Thanks in advance -- Ing. J. Martin Longo Depto. Gestion Informatica SID - UNCuyo http://sid.uncu.edu.ar
