Lexicographica. Series Maior features monographs and edited volumes on the topics of lexicography and meta-lexicography. Works from the broader domain of lexicology are also included, provided they strengthen the theoretical, methodological and empirical basis of lexicography and meta-lexicography. The almost 150 books published in the series since its founding in 1984 clearly reflect the main themes and developments of the field. The publications focus on aspects of lexicography such as micro- and macrostructure, typology, history of the discipline, and application-oriented lexicographical documentation.

Beginning with 1953, entries for Motion pictures and filmstrips, Music and phonorecords form separate parts of the Library of Congress catalogue. Entries for Maps and atlases were issued separately 1953-1955.
