[Koha] Simple Cataloging Help

[Pedro Faria]

Dear all,
I want to do simple cataloging. I just need to have Title, Author, ISBN, 
Publisher, Year, Genre, Group. What do you propose so achieve such goal? 
I want to make it simple for who catalogs and the MARC form is a bit 
scary... Since we just need these fields I would like show to the user a 
form with these values. Should I create another framework (MARC 
structure...) Needing help...

Thanks
