The first part of the volume, to folio 151, is largely legal, the remainder historical. At the end is an index to the collections, of which the first folio is lost (folio 239). There are two transcripts of the historical section, Adv.MSS.34.3.11 and 34.3.12, which do not however begin until folio 159; they contain additional material, some of which may have been lost in a gap after folio 156, but much of it can never have been included in this volume; it is therefore possible that they are derived from an expanded version, perhaps not or not wholly due to Stewart.
The legal section consists largely of copies of documents from the Justiciary Court and other public records; there is a particular interest in forfeitures, restitutions, and resignations. The historical section is extremely varied: lists of kings, nobility, events, and religious institutions; sheriffs` accounts and taxation of benefices; charters, especially foundations of abbeys and collegiate churches; acts of Parliament. The great majority are known from other primary or secondary sources. A full list of the contents is available.
The manuscript is written by several clerks, with occasional notes apparently by Stewart himself. On folio 19 verso are the lines `Hic liber est meus possum producere testes / Si quis me querit Lodovicus mihi nomen / Erat Steuart jungatur quis scripsit sic nominatur` (repeated with minor variations), together with several examples of Stewart`s signature in various forms. The names Andro Hoge and W Chalmers also occur.
