The aim of presented paper is to outline the concept of the issuing of the seventh volume of the source edition "Codex diplomaticus et epistolaris regni Bohemiae" and its digital version. As a reaction to the changes in the diplomatic material at the end of the 13th century (in connection with the changes of stylization e.g. because of the permeation of the principles of Canon and Roman law into the charters or an influence of professional notaries educated in the domestic notary school in Vyšehrad, or with regard to the emergence of the official books, especially formularies), the editors decided to change a concept of issuing of CDB. In the first phase there will be processed and finished the second part of "Katalog listin a listů k VII. dílu Českého diplomatáře" and its on-line publishing in a form of database on website. The second phase will be connected with the preparation of the critical edition in a traditional printed as well as a digital form.

These manuscripts are identified as a product of a scriptorium in Břevnov in the era of the abbot Meinhardus (1035/1044–1089). and Der Beitrag beschäftigt sich mit einer Gruppe von Handschriften, und zwar mit der Handschrift der Klosterbibliothek in Rajhrad/Raygern (R 388: Martyrologium Rajhradense) und mit den zwei Handschriften der Nationalbibliothek in Prag (IX.C.6: Boethii Quadrivium und IV.D.7: Gregorii Magni Homiliae). Diese Handschriften bindet eine gemeinsame Schreiberhand, die als "Glossator B" bezeichnet wurde. Die analysierte Handschriftengruppe wurde als Erzeugnis vom Skriptorium der Benediktinerabtei Břevnov in der Zeit des Abtes Meinhardus von Niederaltaich (1035/1044–1089) identifiziert. Für den "Glossator B" sind die Musikeinträge sehr typisch, seine Arbeit ist oft von Neumen begleitet.
The article deals with content and provenance interpretation of the oldest parchment manuscript fragment which is deposited in the Library of the Department of Auxiliary Historical Sciences and Archive Studies at the Faculty of Arts, MU. The piece is identified as a fragment of Lectionaria officii, which was probably written by the Order of Saint Benedict Benedictines in the first half of the 12th century, which was taken from the binding of one of the books from Bohemian or Moravian Franciscan library.
