how do you find the book id numbers for a resources in logos 4?
in logos 3, you pressed shift, control and alt while clicking on the resource in my library.
Have you checked the resource's info panel? In the upper right hand corner of the resource tab is a "circle with an 'i'" icon. Click that, and scroll down to the bottom.
Out of curiosity… are you using an older computer? Is there a reason you haven't updated to the free L5 engine?
