Changing the name "Product"  in the productbook compont can sometimes be wishfull.

Lets say you have a site about Adopting Animals and you don't want your Productbook say "Products" but "Adaption Animals" since this is so much nicer

How to do this:
Just replace the "product" tekst in the language file english.php
You wil find this file in the \component\com_productbook\language

The extensions JoomlaExplorer lets you do this online.

Most item names come from this, so for instance you can replace

  var $PRODUBK_0038 = 'Products Book';

With
  var $PRODUBK_0038 = 'Adoption Animals';

First you could change the frontend items as of line 173 // Frontend down to get the feel of it.

You can of course put in any productname you want....
Like:

• Car catalog
• Fisch book
• Flower book
• Booting overview

Just fit it to reflect your need
