In addition to sheet music, G. Henle Publishers also produces scholarly complete editions, books, reference works, and journals.

[6] The typical blue book cover, which is still used today, was chosen at that time, as was the design of the title font, created by Joseph Lehnacker (1895–1965).

[8] From the start, Günter Henle attached great importance to 'clear and precise engraving, a balanced arrangement of the pages, legible type-faces and aesthetically pleasing typesetting of the word parts.

[11] The founder of the publishing house maintained close contacts and friendships with Gieseking and numerous important musicians of his time, including Claudio Arrau, Erich Kleiber, Yehudi Menuhin, Igor Oistrakh, Arthur Rubinstein and Rudolf Serkin.

All Urtext editions are subject to strict scholarly and aesthetic criteria with regard to source and text criticism, correctness, beauty and user-friendly presentation of the music (pagination, fingerings etc.

In 1981, when the publishing house appeared at the first German Music Fair in Tokyo, Japan, G. Henle USA Inc. was also founded in North America, initially as a joint venture based in St. Louis, Missouri.

Since then, G. Henle Verlag has been represented exclusively on the North American market by the Hal Leonard Corporation in Milwaukee, Wisconsin.

The heart of the G. Henle Verlag catalogue are the Urtext[5] (original text) editions: musicologically researched, accurate musical texts for practising musicians, they contain an explanatory apparatus expounding on the sources consulted (autographs, copies, early printed editions) and on the readings chosen (‘Critical Report’).

[24] The Urtext programme[25] covers almost the entire range of important piano music and chamber music for smaller orchestrations, complete piano works by J. S. Bach, Beethoven, Brahms, Chopin, Debussy, Joseph Haydn, W. A. Mozart, Schubert, Robert Schumann; in addition, numerous other selected piano works for two or four hands (including Dvořák, Granados, Grieg, Handel, Liszt, Mendelssohn, Rachmaninov, Ravel, Reger, Satie, Scarlatti, Scriabin and many more), as well as organ works and the entire standard repertoire for chamber music ensemble.

The entire repertoire of G. Henle Verlag for piano solo (author: Rolf Koenen), violin (Ernst Schliephake) and flute (András Adorján) has been classified in difficulty levels from 1–9.
