They are more than commonplace books and apparently in their thousands in Italian Libraries, sometimes self illustrated- others are written and have illustrators paid for. Some have printed (when printing became common) pictures stuck on the leaves.
(Wikipedia on Commonplace Books)The Italian peninsula, during the course of the 14th-century, was the site of a development of two new forms of book production: the deluxe registry book and the zibaldone (or hodgepodge book). What differentiated these two forms was their language of composition: a vernacular.Giovanni Rucellai, the compiler of one of the most sophisticated examples of the genre, defined it as a "salad of many herbs."
Zibaldone were always paper codices of small or medium format – never the large desk copies of registry books or other display texts. They also lacked the lining and extensive ornamentation of other deluxe copies. Rather than miniatures, zibaldone often incorporate the author's sketches. Zibaldone were in cursive scripts (first chancery minuscule and later mercantile minuscule) and contained what Armando Petrucci, the renowned palaeographer, describes as "an astonishing variety of poetic and prose texts." Devotional, technical, documentary and literary texts appear side-by-side in no discernible order. The juxtaposition of gabelle taxes paid, currency exchange rates, medicinal remedies, recipes and favourite quotations from Augustine and Virgil portrays a developing secular, literate culture. By far the most popular of literary selections were the works of Dante Alighieri, Francesco Petrarca and Giovanni Boccaccio: the "Three Crowns" of the Florentine vernacular traditions.These collections have been used by modern scholars as a source for interpreting how merchants and artisans interacted with the literature and visual arts of the Florentine Renaissance

I have been told there are some about card playing- but I have not found them yet.
Brunetto Latini made one called Il Tesoretto or Little treasures and you can see it if you google.
