This is a relatively long work which started its life as a bunch of shorter works in the same continuity, which were then edited together to form a single more-or-less coherent narrative. Sometimes this occurs through the addition of a Framing Device or Encyclopedia Exposita to tie the different narrative threads together; sometimes it just means the stories themselves are edited to increase continuity and remove redundant exposition; sometimes they are just put in chronological order (or left in Anachronic Order for artistic purposes).
This is very common in literary science fiction, especially from The '50s and The '60s when there was a shift in the genre from publishing in short-story-dominated magazines to publishing novels. In those circles it's generally referred to as a "fix-up", a name coined by science fiction writer A. E. van Vogt.
Not to related to Patchwork Fic, which is when a fanfic combines characters and/or other elements from different adaptations of the same single story; or to Patchwork Kids, which is when a child's personality and appearance are essentially just a mashup of their parents' own.

- The Silmarillion wasn't even compiled together into its current relatively cohesive form by J.R.R. Tolkien himself, but rather by his son Christopher. To quote the latter's foreword:
The Ainulindalë and Valaquenta, which are given at the beginning, are indeed closely associated with The Silmarillion, but the Akallabêth and Of the Rings of Power, which appear at the end, are (it must be emphasised) wholly separate and independent. They are included according to my father's explicit intention; and by their inclusion the entire history is set forth from the Music of the Ainur in which the world began to the passing of the Ringbearers from the Havens of Mithlond at the end of the Third Age.

- A Hero of Our Time originated as three serialized novellas, Bela (1838), The Fatalist (1839), and Taman (1840), united only by their protagonist Grigory Pechorin and setting, Northern Caucasus. They were then compiled into one big novel, with the author adding the short story Maxim Maximich and the (almost novel-sized) novella Princess Mary to the first omnibus edition in 1940note , and a foreword explaining his authorial intent in the second (1841). Lermontov also wrote what is essentially an Origins Episode for the recurring character of Maxim Maximich, titled A Caucasian, in 1840, but it historically isn't included in the canonical novel, but sometimes published under the same cover as a companion piece.
- The Garden of Sinners is a downplayed example: while it invokes the appearance of a patchwork story, between its multiple sub-novellas appearing in an Anachronic Order, having wildly fluctuating lengths, and getting written and published over a period of several years, it is not so much a compilation, as a single novel with multiple expansions. The first to be written were the first five chapters/novellas, Overlooking View to Paradox Spiral, which are also the only ones to fully employ Anachronic Order for thematic effect. Nasu then wrote and published two more novellas, Oblivion Recorder and Murder Speculation, Part 2, a year later to round off dangling plot threads. Ten years after the original publication, the story was again expanded with Future Gospel, consisting of a short story set a decade after the main story, and an interquel novella. Then another five years down the line, Nasu was cajoled into writing one more novella, Final Record, which borders Canon Discontinuity and isn't typically included with the main body of the novel.
