Why this decision was made

The records represent the same work ('Idylls of the King') by the same author (Alfred Tennyson), but they are distinct metadata records due to differences in author name formatting ('Alfred Tennyson' vs 'Baron Alfred Tennyson Tennyson'), source identifiers (Global Grey vs Project Gutenberg ID 610), and descriptions. According to the policy, these should be treated as distinct records despite referring to the same underlying book.
