1728 poetry » 1724 poetry, 1722 poetry, 1798 poetry
1722 early » 1727 early
28 poetry » 8 poetry, 6 poetry, 3 poetry
21 early » 2.1 early, 1 early, 11 early
22 early » 12 early, 1.2 early

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %business ethics %((28 poetry) OR (1728 poetry)) %((21 early) OR (((((22 early) OR (1722 early))) OR (2 early)))) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%business ethics %((28 poetry) OR (1728 poetry)) %((21 early) or (((((22 early) or (1722 early))) or (2 early)))) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %business ethics %((28 poetry) OR (1728 poetry)) %((21 early) or (((((22 early) or (1722 early))) or (2 early)))) works to 1800%22*.
