The easy way to start is with the numbers: over 120 published titles in 2025, more than 30 EPUB editions and over 10 audiobooks. The numbers are nice, but they are a consequence. The point is the ecosystem — a chain of connected products where each piece feeds the next, from manuscript, through a community of authors, to a reader who finds, buys and rates the book.
The Librum publishing house is not „a website". Here a whole publishing infrastructure was built: a house that publishes, a club that gathers authors, tools that speed up production, printing for small runs, a shop and a social network for readers. Each of these would be a product on its own. Together they form a system that is hard to copy. Here is how they connect.
What a publishing ecosystem is
A publishing ecosystem is a set of connected products and services that take a manuscript through the entire life cycle of a book — from the first text to the rating of a satisfied reader — without retyping data from tool to tool. Instead of being separate sites, the parts work for one another: the author community feeds the publishing house with manuscripts, tools speed up production, printing covers small runs, the shop closes the channel, and the reader network returns data on what to publish next.
The Librum ecosystem today consists of eight connected products. Below, each is described through two things: what it does on its own and how it fits into the whole.
The eight products of the Librum ecosystem
Publishing house — librum.rs
Everything starts with the Librum publishing house. In 2025 it pushed out over 120 titles, with more than 30 EPUB editions and over 10 audiobooks. That is the book in every format a reader looks for today. It is serious output for a single year and needs production that does not stop at the editor and designer.
So the publishing house is the entry point of the ecosystem. A manuscript that comes in here later ends up in the editing tools, in printing, in the shop and in front of readers on Knjigopolis. One book, one flow.
Output in 2025:
| Metric | Value |
|---|---|
| Published titles | 120+ |
| EPUB editions | 30+ |
| Audiobooks | 10+ |
Author websites
For more than 5 authors, personal websites were built — a place where the author owns their name, their bio, their books and a direct channel to readers. The author becomes a host at their own address that works for them around the clock.
In the ecosystem, an author site works as a funnel. A visitor who comes for one name discovers the publishing house, joins Librum Club and buys in the shop. The author brand becomes an entrance to the whole system.
Librum Club — librum.club
In January 2026 Librum Club launched, a community for authors. In the first six months 400 authors registered, each writing on average 2 texts. These are people who actively create, and every text is a potential future title.
So the club works as a talent pipeline for the publishing house. Manuscripts are born inside the system — visible, measurable and tied to an author who already has an account, a profile and a history. A community that writes is the cheapest and highest-quality source of content a publisher can have.
Quiz — kviz.librum.club
In April 2026 kviz.librum.club launched, already counting over 2000 users. The quiz looks like fun, but it is really an engagement engine: light, shareable content that brings in people who are not yet authors or buyers — curious readers.
Those users are the top of the funnel. Someone who solves a quiz today opens Knjigopolis tomorrow, buys a book the day after, and in a year maybe writes in the club. Engagement is measured by the path through the ecosystem, and the quiz is the cheapest ticket in.
Ecosystem growth:
| Period | Product | Metric |
|---|---|---|
| 2025 | Publishing house | 120+ titles |
| January 2026 | Librum Club | 400 authors |
| April 2026 | Quiz | 2000+ users |
Librum House — librum.house
Librum House is a global website for authors and publishing services: text editing, cover design, layout, proofreading and translation — all in one place, in English, for the market beyond the region. This is where the Librum publishing house grows from a local house into a service available to an author anywhere.
Librum House differs from an ordinary agency by the many tools built into the site itself. Through the tools, the author starts and tracks the work, instead of sending emails and waiting for quotes. That is how a publishing service scales: the same team serves many more authors, because the tool does what a person otherwise would.
Librum Print — stampaknjige.rs
stampaknjige.rs (Librum Print) is printing tailored for small runs under 100 copies, digital and offset. Classic print shops turn their backs on small authors because a run of 30 or 50 books is not worth it. Librum put exactly that segment at the center.
The small run closes the loop for the ecosystem. An author from the club can print the first 50 copies with no risk, test the market, and only then go to a bigger run. Print on demand means a book can exist without being a hit — and that is exactly what a small author needs.
Librum Shop — izdavackakuca.com
The sales channel is izdavackakuca.com (Librum Shop), where everything the ecosystem produces reaches the buyer. With its own shop, the margin and the reader relationship stay at home, instead of depending on other shelves and other commissions.
The shop is the meeting point of all the earlier parts: a title from the house, in a format prepared at House, printed at Print, discovered via Knjigopolis. A sale is a consequence of the whole system.
Knjigopolis — knjigopolis.com
At the top of it all is Knjigopolis, a local Balkan social network for readers and an answer to Goodreads. Readers keep shelves here, rate, follow each other and discover books in a language and context that global platforms do not understand.
For the ecosystem, Knjigopolis is where the loop closes and opens again. A reader discovers a book, rates it, and that rating helps the next reader find it. Data about what is being read flows back to the house as a signal of what to publish next. A community of readers thus becomes both marketing and market research at once.
The point is not the numbers
120 books, 400 authors, 2000 users — each number is nice on its own, but the point is that they are all connected. An author from the club writes a book the house publishes, House prepares, Print prints, the Shop sells, and Knjigopolis recommends to the next reader.
That is what we build at GoSimple: ecosystems where the parts work for one another. If you too have an idea bigger than a single website, get in touch. The Librum publishing house is proof that it can be built at home.
