London continued to be the centre for literary publications ranging from cheap ephemera broadsides and ballads to works offering self-improvement, such as dictionaries, and new fiction, called novels, for entertainment. The ongoing wars with the Dutch resulted in satires and lampoons on the government and the court. Parliament was increasingly concerned with the royal succession and manuscript newsbooks carried information and gossip from London and the continent into the provinces, including the Indian wars in New England. The taste in theatre favoured witty contemporary comedies by William Wycherley, John Dryden, and Aphra Behn and sensational tragedies by new dramatists including Thomas Otway and Nathaniel Lee. Productions often featured spectacular scenery, music, and special effects. Didactic writers such as Richard Baxter and Samuel Clarke offered guidance for humble readers in everyday devotional situations.
