Newbie loop question

Hi, i'd like to do a script that would import data from several records to several others (visible through a portal.

Ok, i have a lot of bibliographical references through a DB with a lot of of related tables. To simplify everything, I want to do a "bibliography" layout. I was thinking of adding something like a button with a script that would import all the data from all of the records. This bibliography layout would be associated with another table (say "Biblio_ref") with one record for one references. That would let me see all the references at the same time through a portal in "Bibliography".

I would like to know how i could do this. I'm not sure if it's clear for you guys, maybe i'm doing something simple in a much too complex way.... I tried to do a script and the problem was that i only got the first references from every records. You see, in all the tables, i used the same fonctionality has i was just describing (a sub-table with all the references and a main one with a portal showing all the references). I was thinking that maybe the loop function could help me, but i've never used it so i'm not exactly sure if it can help and how to use it.

So, basically, what I need is a way to go through all the sub-tables and import all the data to another sub-table so i would be able to see everything in my main "bibliography" table.

Thanks for reading this through, and an even bigger thanks if you can help me.
