For George Berkeley: Letters, with the exception of two letters which appear in their proper chronological order, the database has adopted the same ordering of material found in The Works of George Berkeley, edited by T. E. Jessop and A. A. Luce. The texts have been checked closely against microfilm and microfiche of the original source material. Many of the modernizations adopted by Jessop and Luce have been followed. Unless errors have been introduced, all punctuation discrepancies between this database and the texts of Jessop and Luce may be explained by consulting the original editions. None of the editorial apparatus of Jessop and Luce is included in the database, and all text found in the database (with a few minor editorial exceptions which are noted) was authored by Berkeley.
