Sorting by date in iBooks

I subscribe to a weekly and monthly magazine in epub format. I would like to find out how I can sort these by date so that I can find the relevant date issue quickly. At present I have a collection which keeps them all in the same place but it doesn't help me find specific editions without opening each one and checking the date. Can you please explain this to me.
Thank you in advance
