Enjoying the sensation their 1823 poem created in simple newspaper column style, the Troy Sentinel created a few broadsheet versions of the poem, both dated approximately to 1830, though, obviously, they would have come out in separate years. One is owned by the Museum of the City of New York, referred to as "Troy Broad MCNY", and one is from the Anne Haight Collection at Carnegie Mellon University, Troy Broad AHC.

The Troy Broad MCNY was originally mailed to Clement Moore by Norman Tuttle, the owner of the Troy Sentinel. He enclosed it with a letter answering Moore's question - no, he had not known who the author was when the poem was originally published. But since that time he had learned the author was Moore. That letter was copied by Moore's grandson and sent to Henry Litchfield West, who had written an article in the Bookman. Casimir Moore's intention was to shut down the discussion of another claimant, Henry Livingston, to the poem's authorship. Read more about this possible smoking gun. The Troy Broad AHC has no known connection with Moore or his family.

The main differences between these two versions are artistic rather than editorial.

Troy Broad MCNY
    Elaborate, Celtic-like border with corner sqares
    "A GIFT FOR CHRISTMAS"
    Preface
    Graphic of Santa flying his sleigh onto a rooftop
    The poem in two columns
    "Published and Sold by N. TUTTLE at his Book and Job Printing Offices,
        225 River-street, Troy."

Troy Broad AHC
    Common, decorative rectangular border
    Graphic of Santa flying his sleigh onto a rooftop
    Preface
    "- Troy Sent'l."
    The poem in two columns

There are few editorial differences between these two broadsheets. The two significant ones are line 21 and line 41. In the Troy Broad MCNY, the line reads "now, Prancer and Vixen!". The Troy Broad AHC reads "now, Prancer! now, Vixen!". Since the Troy Broad MCNY was the version on which Moore based his 1844 publication, that reindeer name rhythm is the one with which we're familiar. In line 41, the Troy Broad has Santa holding a pipe "tight" in his teeth, while the Troy Broad AHC describes him as holding the pipe "just" in his teeth.

The change in line 36 shows a typo (liked instead of like) in the Troy Broad MCNY, which doesn't appear in the Troy Broad AHC. Since punctuation is the main place where editions vary, it's rather surprising that only a single punctuation difference (line 28 - hyphen vs comma) appears.

'Twas the night before Christmas, when all thro' the house

The Troy Broad MCNY is a very important version of the Christmas poem because it's the one on which Clement Moore based his 1844 publication. Let's look first at the large number of differences between the originally published version of the poem (Troy 1823), and the approximately 1830 broadsheet version of the poem (Troy Broad MCNY) that Tuttle mailed to Moore before Moore included the poem in his 1844 book.

There are 55 differences between Troy 1823 and Troy Broad MCNY, counting reindeer names as only 2!

The Troy Broad MCNY was enclosed in a letter that Norman Tuttle wrote to Clement Moore, clearly answering a question of Moore's - whether Tuttle had known the author of the poem at the time it was published. Tuttle said he didn't. If Moore were actually the author of the poem, you'd expect that what he printed in his 1844 book would have been more nearly similar to the 1823 poem that went unedited, as far as we know, out of his home. But he didn't. Instead, he based his published poem on changes made by the editor of the Troy Sentinel, certainly a strange thing for a poet of any pride to do. And it wasn't that he found a host of editorial changes that he wanted to make in the poem. He wanted ALMOST EXACTLY those changes made by the Troy Sentinel editor.

There are a total of thirteen differences between the Troy Broad MCNY and the version in Moore's 1844 'Poems.' Eight of the differences are due to capitalization, a typo, and punctuation. Only five of the changes are significant. In line 1, Moore expands thro' into the more correct through, as had been done by Charles Fenno Hoffman in his 1837 New-York Book of Poetry. In line 25 Moore adds 'that' to the leaves line, as Hoffman did, but brings back the original 'dry' for better rhythm.

Troy 1823	As dry leaves before the wild hurricane fly,
Troy Broad MCNY	As dry leaves before the wild hurricane fly,
Hoffman 1837	As leaves that before the wild hurricane fly,
Moore 1844	As dry leaves that before the wild hurricane fly,

In line 35 Moore again took Hoffman's rhythm modification by exchanging 'he had' for 'was. But the changes that everyone notices are to the reindeer names. In Moore's 1844 version, Dunder became Donder, and Blixem, Blitzen. Hoffman had already changed Dunder to Donder, so what we can honestly credit Moore with is the change of Blixem (or Blixen or Nixen, per other versions) to Blitzen.
