Roberto Borzellino: 139 Books, 23 Breakouts in 30 Days
Roberto Borzellino has 139 tracked KDP books, with 23 breakouts in 30 days. See his pricing, estimated earnings, publishing pace, categories and catalog strategy.
Roberto Borzellino's most useful publishing lesson is the value of a connected catalog. Of 139 tracked books, 73 appeared on Best Sellers lists during the last 30 days, and 23 qualified as breakouts. His books combine Italian-language learning with detective fiction, historical novels, glossaries and exercises. Rather than relying on one title, he publishes related books that give readers several ways to continue studying Italian.
The catalog is entirely indie / KDP, according to the available data. KDPTop estimates monthly revenue at $1,879 across 303 units. Those figures come from sales-rank modelling, not Amazon's reported sales. They are useful for comparing the catalog's apparent performance, but they are not verified earnings statements. The more interesting question is how Borzellino connects subject matter, series, pricing and publishing frequency.
A 139-book catalog built around Italian learning
Roberto Borzellino has 139 tracked books, and all 139 are classified as independently published through KDP. His catalog covers several book types, including fiction, early readers, nonfiction, study guides and reference material. The category mix includes Study Aids & Revision Guides, Language, Linguistics & Writing, Crime, Thriller & Mystery, Italian, Studying & Workbooks and Study Guides.
That combination is more coherent than the category list might suggest. The recurring product is not simply an Italian textbook or a detective novel. It is fiction used as a language-learning format. Readers encounter stories while also getting learning support through bilingual glossaries, exercises and answer keys.
Two recurring series illustrate the approach. Misteri Italiani uses detective stories for learners at different proficiency levels. Testimoni d'Italia connects historical fiction with structured language exercises. These are recognisable product families rather than unrelated titles competing for the same reader without a clear connection.
For another publisher, the lesson is to identify a specific reader need that can support several formats. A language learner may want a short story, a longer novel, a collection or a workbook. A publisher who understands that progression can build a catalog around it. The opportunity is in serving the same audience with genuinely useful follow-up products, not simply changing a cover and repeating the same material.

The leading estimated monthly revenue figure in the supplied book data is $117. Three books reach that amount: Delitti a Roma: The Complete Collection. All 5 Novels. Learn Italian Through Easy Detective Stories with Arthur Finch. A2-B1 Beginner-Intermediate, with ... indagini di Arthur Finch) (Italian Edition), Furto al Museo degli Uffizi: Learn Italian through Easy Detective Stories – A2/B1 (Misteri Italiani - Book 1) (Misteri Italiani. Edward Blake: Pre-Intermediate (A2–B1)) (Italian Edition), and Learn Italian with a Historical Novel. La Copista di Dante: 3 Bilingual Glossaries, 25 Exercises with Answer Key, Creative Writing - Intermediate B1-B2 (Testimoni d’Italia EN B1-B2) (Italian Edition).
The estimated monthly revenue for each is $117. Their estimated monthly unit figures are 9 apiece. The difference is in their subject and format. One is a five-novel detective collection, one is an individual mystery story, and one combines historical fiction with language exercises. That suggests the same audience can support more than one reading experience.
Strada senza uscita: Learn Italian B1–B2 An Intense Dramatic Novel with Bilingual Glossaries and 33 Exercises (Italian Edition) follows with estimated monthly revenue of $84 and 12 estimated monthly units. Its estimated unit figure is higher than the three $117 titles, but its price is lower. This is a useful reminder that revenue depends on both estimated unit volume and price, not just the number of readers.
Misteri Italiani. The Collection. Books 1 to 5: Learn Italian through Mystery Stories. Intermediate B1-B2 (Italian Edition) has estimated monthly revenue of $90. Learn Italian with 5 Historical Novels. Testimoni d'Italia. Books 1-5: Complete Collection. 15 Bilingual Glossaries, 125 Exercises with Answer Key, Creative ... d’Italia EN B1-B2) (Italian Edition) reaches $78. The two additional Misteri Italiani collections show estimated monthly revenue of $65 and $60. Together, these titles demonstrate the commercial role of collections: they package existing series material into a larger purchase.
For publishers considering a series, the practical point is to plan collection editions alongside individual books. A collection gives an established reader another purchase option. It can also make a series easier to approach for someone who prefers a single larger volume. The data does not prove that collections generate additional sales rather than replacing individual purchases, so that distinction should be tested rather than assumed.

The pricing strategy favours accessible entry points

The median listed price across the tracked catalog is $4.99. The lower quartile is also $4.99, while the upper quartile is $8.69. The price distribution chart covers 64 books with a recorded price, rather than all 139 tracked titles. That distinction matters when interpreting the results.
Of those 64 priced books, 38 fall below $5. Another 13 are priced from $5 to $9.99, and 11 sit between $10 and $14.99. None are in the $15 to $19.99 range, while 2 are priced at $20 or more. This is a catalog weighted towards lower-priced products, although the leading books show that Borzellino also sells higher-priced collections.
Delitti a Roma, Furto al Museo degli Uffizi and La Copista di Dante are each priced at $12.99. Strada senza uscita is priced at $6.99. The two larger Misteri Italiani collections in the leading group are priced at $9.99. These prices suggest a distinction between individual reading products and larger packages of material.
For a new publisher, the useful approach is to give each format a clear pricing role. An individual story can offer a relatively accessible purchase. A collection can charge more because it contains multiple stories or additional learning material. A workbook can justify its price through exercises, answer keys and other practical content. The point is not to copy Borzellino's prices. It is to make the difference in value clear enough that readers understand why one edition costs more than another.
A low price alone does not establish a good publishing opportunity. Production costs, printing costs, royalties, advertising and actual conversion rates are not provided here. Estimated revenue is not equivalent to author profit. Publishers should calculate their own margins before using a similar pricing structure.

The publishing pace accelerated sharply in 2026

| Year | Books |

| 2020 | 1 |
| 2021 | 1 |
| 2022 | 2 |
| 2023 | 15 |
| 2024 | 4 |
| 2025 | 12 |
| 2026 | 43 |
The annual release figures show a clear change in publishing pace. Borzellino published 1 tracked book in 2020, 1 in 2021 and 2 in 2022. The figure rose to 15 in 2023, then dropped to 4 in 2024. In 2025, it reached 12. The supplied 2026 figure is 43.
The latest release date in the data is 2026-10-28, while the first release is dated 2020-06-19. The 2026 figure therefore reflects a substantial increase in catalog activity compared with earlier years. It should not be treated as a complete calendar-year comparison because the available release period ends in October.
The recent activity figures are particularly striking. Borzellino published 37 new books in the last 30 days, and 23 of those qualified as breakouts. Under KDPTop's definition, a breakout is a new book on a New Releases list within the last 60 days that reached a Best Sellers list. This is a specific measure of recent list visibility, not proof that every new release is a commercial success.
A release schedule of this scale is not a sensible target for every independent publisher. The data does not reveal how much time Borzellino spends writing, editing, translating, formatting or preparing covers. It also does not show whether work is completed in-house or with outside help. A publisher should not assume that matching the number of releases will produce similar results.
The more useful lesson is to develop a repeatable production system. Related books can share a defined audience, editorial standards, formatting conventions and a clear series identity. Those efficiencies can make a catalog easier to maintain. But quality still has to justify the next purchase. Releasing more books is only useful when each one gives readers a reason to buy.
Category visibility comes from serving overlapping readers
Show the data
| Category | Books on its lists |
|---|---|
| Study Aids & Revision Guides | 50 |
| Language, Linguistics & Writing | 50 |
| Crime, Thriller & Mystery | 30 |
| Italian | 27 |
| Studying & Workbooks | 9 |
| Study Guides | 9 |
The category chart shows 50 appearances in Study Aids & Revision Guides and 50 in Language, Linguistics & Writing. Crime, Thriller & Mystery accounts for 30, while Italian accounts for 27. Studying & Workbooks and Study Guides each account for 9.
These figures show how the catalog reaches readers through more than one shopping interest. Someone looking for Italian study material may be interested in a graded story. Someone browsing mystery fiction may be interested in a detective novel that also teaches vocabulary. The overlap gives Borzellino more than one potential route to discovery.
The key is that the categories connect to the actual content. Misteri Italiani is not simply a mystery title placed in a language category without supporting material. Its positioning includes Italian learning, proficiency levels and English-language learning support. La Copista di Dante similarly combines a historical novel with glossaries and exercises. The category strategy has a product behind it.
For publishers, this is a useful distinction. Choosing categories should start with the book's actual content and intended reader. A coloring book, cookbook or children's workbook should not be pushed into unrelated categories just because they appear less competitive. The goal is to find the relevant category where the book's format and subject make sense.
KDPTop's opportunity score is a 0-100 measure of how much room a category leaves new indie books, with higher scores indicating more room. No opportunity scores are supplied for Borzellino's categories here, so the chart cannot establish which category offers the best opening for a new publisher. Category visibility and category opportunity are different questions. A category that already contains many of an author's chart appearances is not automatically the easiest place for a newcomer to compete.
Review counts suggest a catalog built beyond individual hits
Show the data
| Reviews | Books |
|---|---|
| 0 | 60 |
| 1–9 | 73 |
| 10–49 | 6 |
| 50–199 | 0 |
| 200–999 | 0 |
| 1000+ | 0 |
The tracked catalog has 233 reviews in total, an average rating of 4.4 and a median of just 2 reviews per book. The distribution is revealing. Sixty books have no reviews, 73 have between 1 and 9, and 6 have between 10 and 49. None appear in the higher review ranges shown in the chart.
The median matters more than the total when assessing the typical title. A catalog with 233 reviews might initially sound as though every book has a substantial reader history. In reality, most titles have relatively few reviews. The data describes a broad catalog where list appearances and estimated sales are not dependent on every individual title accumulating hundreds of reviews.
The leading books illustrate the range. Furto al Museo degli Uffizi has 11 reviews and a 4.5 rating. Strada senza uscita has 13 reviews and a 4.6 rating. Delitti a Roma has 1 review and a 5.0 rating. Those ratings should be read cautiously because small review totals provide limited evidence about the wider reader experience.
For publishers, the lesson is not to ignore reviews or to assume they are unnecessary. It is to avoid treating a large review count as the only measure of a book's commercial potential. A clearly targeted title with useful content can still have relatively few reviews. At the same time, a 5.0 rating based on one review is not strong evidence of consistent reader satisfaction.
The stronger approach is to build products that fulfil their descriptions, encourage honest reader feedback and connect naturally to other relevant books. A catalog becomes more useful when the next purchase solves another problem for the same audience. Borzellino's series structure provides a practical example of that idea, even though the available numbers cannot establish exactly how much cross-selling occurs.
What another KDP publisher can learn from the numbers
The catalog's estimated monthly revenue is $1,879, based on 303 estimated monthly units. The leading individual title contributes an estimated $117 per month. These figures put the scale of the business in perspective. The overall catalog estimate is much larger than the estimate for any single leading book, which supports the idea that Borzellino's publishing model depends on multiple titles rather than one runaway bestseller.
That does not mean every title contributes equally or that every book is profitable. Sales estimates are modelled from BSR, Amazon Best Sellers Rank, where a lower rank is better. Amazon does not report the unit and revenue figures used here. Changes in rank can affect estimates, and the available data does not include advertising expenditure, royalty statements, printing costs, refunds or production expenses.
The most transferable part of the strategy is the connection between product, audience and catalog. Borzellino's books give Italian learners fiction, graded reading experiences, vocabulary support and exercises. The collections extend those same products into larger packages. His publishing activity also shows how a consistent subject can support several related formats.
A publisher working in coloring books could apply the same principle through related themes and age levels. A cookbook publisher might build connected titles around a specific cooking method or dietary audience. A children's publisher could create a reading progression with consistent characters and increasing difficulty. These are applications of the catalog principle, not claims that those categories will produce the same sales.
The sensible next step is to test one tightly defined audience and one useful product before expanding. Check whether the book satisfies a real reader need, whether the price reflects its contents, and whether a follow-up title would offer something different. Borzellino's 139-book catalog is evidence of sustained catalog building. It is not evidence that publishing volume alone creates demand.
Key takeaways
- Build a connected catalog around one identifiable audience instead of publishing unrelated titles without a shared reader need.
- Use individual books as accessible entry points and collections as higher-value packages with clearly explained additional content.
- Treat the 23 recent breakouts as evidence of Best Sellers list visibility, not as proof of guaranteed sales or profitability.
- Choose categories that accurately describe the book and its intended reader rather than chasing category placement without content relevance.
- Measure catalog performance alongside production costs, royalties and advertising because estimated monthly revenue is not author profit.
