Certain Personal Matters is an 1897 collection of essays selected by H. G. Wells from among the many short essays and ephemeral pieces he had written since 1893. The book consists of thirty-nine pieces ranging from about eight hundred to two thousand words in length. A one-shilling reprint (two shillings in cloth) was issued in 1901 by T. Fisher Unwin. The essays in Certain Personal Matters are written from a consistent first-person perspective, but only one (ironically, given the title) describes an identifiable event in Wells's life-how he responded to being diagnosed with tuberculosis in the fall of 1887.
