Critics argue that the large number of similarities between the Book of Mormon and the Bible suggest that Joseph Smith is guilty of plagiarism. While the characters in the Book of Mormon often give credit to the Biblical authors they are quoting (see 1 Nephi 20-21/2 Nephi 7-8/Mosiah 14/3 Nephi 12-14, 22, 24-25), there are other instances where it seems significant sections of the Bible are borrowed by Book of Mormon characters without citing the original authors (see Moroni 10:8-23/Ether 12/Moroni 7:44-46/Alma 13:14-20). There are many explanations justifying the existence of Biblical passages in the Book of Mormon (click here for my take). The most common arguments are that the Holy Spirit and ministering angels are capable of revealing the same doctrines to people separated across time and location (2 Nephi 29:7-8/Alma 39:17-19), or that the Book of Mormon and the Bible are both citing from earlier source material that has been lost over time (1 Nephi 13:23-27/Jacob 5).
Regardless of how authors in the Book of Mormon were able to write passages similar to passages in the Bible, it should be acknowledged that citing another author’s work without giving credit to the original author (plagiarism) is common in the Bible. It is therefore unjustified to fault the Book of Mormon for borrowed concepts without also condemning the Biblical prophets for the same actions.

From what I understand it was common practice in the ancient world, and even into the beginning of the Renaissance to not cite sources when you were presenting a philosophical or religious perspective. The concept of plagiarism arose fairly recently in the Earth’s History when people first began to make a living based on the written word, rather than other forms of work. Before this time ideas were not considered to belong to anyone. You simply didn’t have intellectual property as we do today. It arose with two other movements: That of the concept of value being based on the creator rather than the quality, and the specialized studies that developed in the Universities.
As such, anything written before the Renaissance would not have even made consideration as to what we consider Plagiarism, as it simply didn’t matter back then.
That’s a good point. The writings of the Biblical prophets are full of borrowed ideas and it is nearly impossible to determine who the original author may have been
