This is the description of essence reaver:
+65 Attack Damage
+20% Critical Strike ChanceUNIQUE Passive: +10% Cooldown Reduction.
UNIQUE Passive: Gain
increasingly more Cooldown Reduction from Critical Strike Chance
provided by other sources (maximum +20% additional Cooldown Reduction
at 30% Critical Strike Chance).
UNIQUE Passive: Critical strikes restore 3% of your maximum Mana pool.
I wanted to know, if the critical chance of the item itself (20%) is getting involved here as well. When I for instance have 10% critical chance through runes and would buy essence reaver, would I gain 30% cdr instantly?

No my friend it does not, you can read it here
you can see that they specify
"Gain additional Cooldown Reduction depending on Critical Strike chance from other sources."
EDIT: Sometimes all we need is to read things carefully. :)
