Sammelbände refers to a collection of manuscript texts (separately printed) that are bound together. 
Unlike today, most publications in the early years of the printing press were not sold as individual books. More often, the unbound quartos and folios were purchased or collected and privately bound into anthologies of related texts. 
Sammelbände and William Caxton
William Caxton appeared to follow the established manuscript tradition of producing booklets or fascicles of individual works or groups of works that would later be bought together for a patron or buyer. 
Nearly forty of these tract volumes, or Sammelbände, have been reconstructed from the evidence of now separately bound volumes. They indicate the nature of early readership of Caxton’s work, and they also allow historians to infer something about Caxton’s own sense of his projects.
Perhaps most famous and extensive of his Sammelbände work was the collection made out of Caxton’s 1476-8 productions, known since the time of Caxton scholar William Blades as “the volume purchased by King George I from the estate of Bishop John Moore in 1714.”  This volume is a veritable compendium of Caxton’s first run of vernacular poetry, and the texts within appear as follows:
- John Lydgate, Stans ad Mensam
- Burgh, Cato’s Distichs
- John Lydgate, The Churl and the Bird (2nd edn)
- John Lydgate, Horse Goose and Sheep (2nd edn)
- John Lydgate, The Temple of Glas
- Geoffrey Chaucer, The Temple of Brass (The Parliament of Fowls), also containing Scogan’s Moral Balad, and Chaucer’s ballads Truth, Fortune, and the Envoy to Scogan
- The Book of Cutesye
- Geoffrey Chaucer, Anelida and Arcite, also containing the Complaint to his Purse and a collection of verses known as the Sayings of Chaucer
Caxton had several motives in this Sammelbände. There was a need to legitimate his press in the context of English vernacular culture, a need to secure an initial set of commercial buyers or patrons for his work, and the need to demonstrate the possibilities of continental types for the presentation of English verse. 
Sammelbände from Tudor Period
Modern students of early Tudor literature only rarely encounter extant Sammelbände, most of which were disbound in the nineteenth century.
Yet printed editions of works by (or ascribed to) Geoffrey Chaucer, John Lydgate, Richard Rolle, Margery Kempe, Stephen Hawes, John Skelton, and writers involved in Tudor religious controversy from John Wycliffe to William Tyndale may all be traced to such composite volumes. 
The composition of these volumes reveals a principle of adaptability that is a key aspect of textual production in the early Tudor period.
Effects on Literature
In Caxton’s case specifically, he presents a Lydgatenized  Chaucer, even to the point of giving the Parliament of Fowls a unique new title, The Temple of Brass, to follow Lydgate’s Temple of Glas. It is a testimony both to Caxton’s understanding of vernacular poetry and to the tastes of his clientele. It is a volume centered on a particular publishing event, a volume that contains not only the key texts by canonical authors, but the critical instruction for their understanding: The Book of Curtesye. 
Generally, the creation of Sammelbände can have various effects on the readership of texts. It offers people a larger framework for the understanding of texts within the volumes; these volumes also used prologues and epilogues  in order to provide a further framework for readership. These explanatory additions and the use of advertisements, such as Caxton’s “new and improved edition” of The Canterbury Tales shows the movement away from privileged, aristocratic readership towards the readership of the middle class, solidifying printing as a business and a social progression.
