[Koha] how to add new framework

[vijay kumar]

Dear Member,
Please suggest me how to add a new framework in koha 3
Like 	Audio Cassettes, CDs,
       Books, Booklets, Workbooks,
       CD-ROMs, DVD-ROMs, General Online Resources

I added a new framework at

Home › Administration › MARC Frameworks

but after adding this framework its showing blank pages, no marc tag
will appear.

So where I have to modify or add something so that framework will work...



With regards,
vijay
