Nineteenth-Century Publications about the Book of Mormon (1829-1844) is now available as an online digital collection at the Harold B. Lee Library at this link. Here is an article introducing the collection. You can either browse or search the more than 600 documents, almost one million words, published about the Book of Mormon during the Prophet Joseph’s lifetime.
The work of collecting all of these items was spearheaded by Matt Roper of the Maxwell Institute. It is informally referred to as the Kirkham Project in honor of Francis W. Kirkham, who in the 1930s began collecting newspaper articles about the Book of Mormon from New England and Ohio papers.
The intention of this collection was to bring together everything, from whatever perspective, both detractors and defenders. This will be a wonderful new research tool for those with interests in the early reception of the Book of Mormon.

Cool. Thanks.
Excellent news. I was unaware of this.
I’ve now had a chance to stroll through this. Wow. It is really an important contribution.
