[Koha] Does koha3 have reservations books?

[Juszczak]

Hi
I can't "Place Hold" on item which is not check Out(by admin interface). 
On check out item i can Place Hold(by admin interface). It is normal?
I can't Place Hold in client interface (127.0.1.1) becouse there is no 
Place Hold button. So my question is : Koha 3 have reservation books by 
client or not? I use last stable official version (3.00. ... ) and 
ubuntu 10.4.
Please help.
