This article deals with manuscripts from the library at the Franciscan Convent of Our Lady of Angels in Hradčany. It follows the way the manuscripts were recorded in the existing catalogues for 1675, 1728, 1850 and 1855. The 1850 catalogue preserves a list of manuscripts which indicates that at the time there were 116 manuscripts in the library. When we inspect the catalogue itself we find that the list is not complete and does not record all the manuscripts detailed in the catalogue (with at least fifteen items missing).
