[1] Although the cartulary itself just lists the possessions of the monastery of St. Peter in Selo on the territory of the Republic of Poljica, Croatia and the ways through which they were acquired (such as purchase or grants), it also contains a few important historical notes.

In its basis, the cartulary is actually a chronicle of the Benedictine monastery which was founded around 1080 by a Croatian dignitary and slave owner Petar Crni (Peter the Black).

The cartulary traces the foundation of the monastery of Saint Peter on the territory of the Republic of Poljica, near the hamlet of Sumpetar (located in today's Jesenice) on October 11, 1080, during the reign of king Demetrius Zvonimir.

It chronologically lists land exchanges, and more importantly, the acquisition of slaves, which had been a profitable trade in the region.

Apart from personal names of Slavic, Roman and Christian origin, it also contains vernacular nicknames such as Platichlebi (plati + hleb, "buy bread"), Tilstacossa (Tusta kosa, thick hair), Urascana (Vraškonja) and so on.
