[Koha] How to add code to Marc record and display it in opac?

[Pavlo Bobesiuk]

Hi everyone.
Someone tried to add code of embed book to marc record and display it in
the opac html5 media player?
I have an idea to convert the first pages of books into flipbooks (
www.anyflip.com) and put code in marc record to be able to read them in
opac media player.
For example I would like to add this code:

<iframe style="width:550px;height:350px" src="
http://online.anyflip.com/mepon/fath/"  seamless="seamless" scrolling="no"
frameborder="0" allowtransparency="true" allowfullscreen="true" ></iframe>

to marc record of some book in 856u field, but in opac i see only code, I
don't see frame with flip book.
help me please realize this idea

Paolo
