Use of a ProductLibrary (PRD in the library list) can be very handy.

One added detail... There are actually *two* ProductLibrary slots. 
(Hmmm... I haven't checked lately, maybe IBM added another. I doubt it.)

What I do (more or less, not exact):

1. Check if ProductLibrary #1 has a library.
2. Check if ProductLibrary #2 has a library.
3. If #2 slot is in use, save that entry.
4. If #1 slot is in use, move #1 library to slot #2.
5. Put my library in slot #1.
6. Do my processing.
7. Move #2 library to slot #1.
8. Return any saved library to slot #2. Erase the saved entry.

I kind of treat it like a stack where I push my library onto the top 
and save anything that gets displaced off of the bottom. When I'm 
done, I restore the stack to the condition it was in when I entered 
my process.

One implication is that it's possible to push multiple libraries off 
the bottom. Therefore, you should be prepared to stash and recover 
multiple libraries.
