[Koha] A simple question about Class

[Yaogeng Cheng]

Rachel:

Thanks a lot for your information. I have the following puzzle to be solved.

>> In http://hlt.katipo.co.nz/, if you search by "Understanding your 
>> brain" by Title in the cataloge page. Then you click the TITLE 
>> Understanding your brain, You get the Class J612.82. How did J get 
>> into it? What did J represent and how can I input it into the Koha 
>> system?

>As it's a non fiction book the class is the dewey number.  You enter it
either 
>as part of acquisioning a book or if you've already got an entry, by
clicking on 
>the "modify" button in the group record - you get this page.

>http://hlt.katipo.co.nz/cgi-
bin/koha/modbibitem.pl?bibitem=93999&biblio=41244&submit.x=
>41&submit.y
>=22

However, if I enter J612.82 as part of acquisioning a book, Koha doesn't
take it. By I do can modify it to J612.82 or a123 as you showed me(for that
thanks a lot). It seems in acquisionting page, the dewey number can not take
anything with letters. It can only take numbers. That is the reason why I
ask how did this J get into http://hlt.katipo.co.nz/ dewey part? 

Thanks again!
