This book is devoted to the description of typical trends in development, formation and the present state of English Author Lexicography, the roots of which go back to concordances to the Bible and glossaries of the complete works of Chaucer (xvi c.). Part I, “Linguistic Dictionaries to English Writers,” presents lexicographic analysis of old and new concordances, indices, glossaries and lexicons of famous English writers with special reference to Chaucer, Milton, Shakespeare, and Dickens. It presents a modern scene of author glossaries for unfamiliar words, terms and other groups of writers’ vocabulary (e.g. Shakespeare’s insults and his erotic language). The reader is offered a detailed review of author concordances, glossaries and lexicons on the Internet, along with criticism of printed dictionaries. Part II, “Encyclopedic Reference Works to English Writers,” deals with English author encyclopedic reference books, i.e. encyclopedias, guides and companions; dictionaries of characters and place names; quotations and proverbs, and Internet encyclopedic resources. The book also provides a comprehensive list of references on author lexicography and an Index of Dictionaries to the English Writers (xvi–xxi cc.), including 300 titles of linguistic and encyclopedic dictionaries, which is a reliable user guide in the world of English author lexicography.
