Hi, According to the manual on https://koha-community.org/manual/17.11/html/08_serials.html
there's supposed to be some pre-defined options for Frequency. Two of the pre-defined options are supposed to be: "Without periodicy: some very specific (usually high level science journals) don't have a true periodicity. When you subscribe to the title, you subscribe for 6 issues, which can arrive in 1 year... or 2... There is no regularity or known schedule. Unknown select this if none of the other choices are relevant" What is the difference in the settings of the two? If there is no frequency, and there is no pattern either, how do you define an "empty" number pattern? Kind regards, Maria _______________________________________________ Koha mailing list http://koha-community.org Koha@lists.katipo.co.nz https://lists.katipo.co.nz/mailman/listinfo/koha
