I've mentioned occurrences and anthologies related to African American poetry, now some books. The following titles are "collected" or "selected" works published during the 1990s. Works like these were especially useful for making modern readers aware of historically significant writers.
The Hughes book may have been one of the most popular of the collected works to appear. Scholars interested in Wright were pleased to see the release of his haiku in 1998.
