[Koha] Does koha3 have reservations books?

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.
