Step-by-step explanation:
The late nineteenth century saw several changes in the literary marketplace in America. Several classes of readers developed and increased across the nation, making the literary market more diverse and expansive. Book reviewing also became more standardized and widespread, which helped in promoting and critiquing new works.
However, the publishing industry did not relocate to New York City from New England during this time. Instead, the New York City publishing industry began to flourish in the early twentieth century.
