Written in late Caroline minuscule by Gottschalk, a scribe at Lambach in the late twelfth and early thirteenth century

Interlinear neumes in the St. Gall style; tonary letters are written in the outer margin of each folio drawn on tiers of a column representing an architectural support.

The responsorial liturgy of most feasts begins with a 3- to 5-line initial (sometimes historiated) in red with red vine-stem decoration and violet bands and foliage drawn by Gottschalk; 1-line red capitals are present in many antiphons as are 1-line initials of responses in thick brown uncials traced or dotted with red; rubrics written in red rustic capitals.

Written and decorated by Gottschalk of Lambach in the last quarter of the twelfth century at the Stiftsbibliothek Lambach, in Upper Austria.

Broken for binding scrap at the Lambach bindery in the 15th century. Leaves used as flyleaves and pastedowns in Lambach incunables. The leaves were removed sometime during WWII, were eventually purchased by the Swiss dealer Hans Zinniker, and are now scattered. Many are presumed lost.
