The name Poole's Plus honors the legacy of the American bibliographer and scholar William Frederick Poole. His Index to Periodical Literature, 1802-1906 (published in 7 volumes, and generally referred to as Poole's) is more than the first great index to Anglo-American periodicals. Through it, Poole effectively invented periodical indexing.
