In page William McGonagall:

"

McGonagall's poems were published by his friends, in a series of books bearing variations on the title Poetic Gems. Later editions reprinted the entire series in a single collection called The Complete McGonagall. When a poem was written has no bearing on which of the Poetic Gems books it appears in: the "Address to the Rev. George Gilfillan" and "Requisition to the Queen" were amongst McGonagall's earliest written poems, yet they appear in More Poetic Gems and Last Poetic Gems respectively.[citation needed]
