Final answer:
In publishing, 'galleys' refer to an early version of a manuscript used for review, which is not the final version polished for printing. The passage highlights the presence of these multiple preliminary texts in the Eadwine Psalter.
Step-by-step explanation:
The word 'galleys' in the given context refers to a version of a manuscript that has not been revised. Specifically, it is used to describe pre-publication versions of printed materials that are used for review and proofreading purposes. These versions generally precede the creation of 'proofs,' which include final changes before printing. Galley proofs are typically laid out in a way that resembles the final print layout, but they are not the conclusive editions that go to press. The use of 'galleys' in the passage indicates the existence of multiple preliminary versions or texts for comparison and review before the manuscript was finalized.
