Holding spellbook with Halberd

[Joby]

Can anyone tell me if it was before this era or after, or if in fact it is this era and i'm just doing something wrong. Years back when I played about the 99 era or somewhere around there you use to be able to hold your spellbook while having a halberd equiped. Which time frame was this?

I know I'm not the only one who remembers this.
