Poole's Index to Periodical Literature, 1802-1907

Few works scholarship can match the significance of William Frederick Poole's great Index to Periodical Literature, which remains a core resource for researching nineteenth-century topics.

Increasing in value with each passing year, "Poole's" is more than the first great index to Anglo-American periodicals. Through it, Poole effectively invented periodical indexing.

The edition of Poole's Index, which is available through 19th Century Masterfile is an enhanced edition of 485,000 citations.

Paratext has integrated essential date and title information not contained in the original volumes. This new edition is continuing to be available through the NCM site. The edition integrates:

Index to Periodical Literature, (1802-1881), 2 v. (Boston: Houghton, 1891) Edited by William Frederick Poole.

Index to Periodical Literature, Supplements (Jan.1882--Jan.1907), 5 v. (Boston: Houghton, 1882-1908) Ed. W. F. Poole and W.I. Fletcher.

Index to Periodicals, 1890-1902

"America supplies at a high price and after considerable delay. exhaustive indices to the periodical literature of the world. In the British Empire no such Index is ever attempted."
W.T. Stead, 1890

William T. Stead, like Poole, recognized that the important content of the periodical literature of his time needed to be made more easily accessible to the learned public. However, Stead recognized that British periodicals were not as fully indexed as they should be. The result, Stead's Index to Periodicals was published in thirteen volumes.

• Stead's Index contains more than 265,000 citations.
• More than 200 of the periodical titles indexed by Stead are not indexed by Poole.

Stead's Index is a subject index, like Poole's, but it contains author entries, subject headings and index to portraits as well.
