single word may be spelled several different ways in different sections of the book. Covarrubias was a supporter of phonetic spelling, but his own spelling was not always consistent with the principle. The book takes a broad view of the lexicon, including regionalisms (especially from Old Castile, Toledo, and Andalusia), slang, jargon, and archaisms. The length of entries is uneven, ranging from a few lines to as many as eight pages. Most entries are between ten and twenty lines. Some entries are organized by lexeme, including several words with the same root, which can make searches difficult. Polysemic words – those with several related meanings – are sometimes given separate entries, but sometimes treated within a single article. Spelling or pronunciation variants are likewise sometimes within a single entry but sometimes treated separately. The structure of each entry is likewise inconsistent, featuring a mixture of linguistic and encyclopedic data. Linguistic information includes definitions, examples from literature, Latin equivalents, and etymology. Encyclopedic information includes explanations of the object to which the word refers, issues relating to symbolism, texts that illustrate the topic, moral judgments, and trivia. Not all entries contain each sort of data; the typical content of each entry is the definition and etymology. Supplement Between 1611 and 1612 Covarrubias began work on a supplement to the Treasury. The supplement included new items as well as additions to articles in the original publication. This included a total of 2,179 articles, most corresponding to proper names. Only 429 items in the supplement treated common words; 219 of these were new entries. Particular attention was given to archaisms and technical language. In 2001 a partial transcription of Covarrubias's supplement was published from a manuscript found in the Biblioteca Nacional de Madrid. Reception The initial print run of the Treasury produced just 1,000 copies, and the volume was not reprinted until 1674. In that year Benito Remigio Noydens, a Spanish priest and author, produced a new edition. Noydens' volume added 326 new entries, consisting mainly of encyclopedic information taken from the Glosario de voces oscuras [Glossary of Obscure Voices] by Alejo Venegas. Covarrubias achieved greater recognition after the founding of the Real Academia Española [Royal Spanish Academy] in 1713. The Academy relied on the Treasury as a major source for its own Diccionario de autoridades (1726-1739), the authoritative dictionary now known as the Diccionario de la lengua española.
