The Shelf

  • Corporate Sabotage Field Guide

    Stijn Dejongh

    The Corporate Sabotage Field Guide is a satirical field manual examining how organizations quietly undermine themselves from the inside. Framed like a classified dossier from the Office of Strategic Systemic Decay (OSSD), it catalogs familiar managerial practices — subtly weaponized to erode clarity, stall momentum, and sabotage culture under the guise of professionalism. Darkly humorous, uncomfortably accurate, and grounded in real systems behavior, it’s written for those who recognize that dysfunction often wears a lanyard.

  • Ishi: The Discipline of Determined Intent

    Gareth Holebrook

    Capable people drift into failure through accumulated lapses in attention. By the time collapse becomes visible, erosion has been active for years. Ishi is the discipline that interrupts drift before collapse forces correction.

  • The Effective Software Engineer

    Stefan Ellersdorfer

    What makes a software engineer truly effective? Beyond writing code, effectiveness comes from ethics, sustainable practices, collaboration, and the courage to adapt. The Effective Software Engineer guides you from clean coding habits to organizational empowerment, bridging the gap between developers and leaders.

  • Residues: Time, Change, and Uncertainty in Software Architecture.

    Barry M O’Reilly

    Residuality Theory is a new way to think about the design of software systems that explains why we experience design the way we do, why certain things seem to work only sporadically, and why certain architects get it right so often regardless of which tools they use. A new, scientific approach is defined that fuses Software Engineering, Complexity Science, and Philosophy to produce an entirely new way to think about how to design software. The result is a theoretical base that allows architecture to finally become its own discipline.

  • The Architect’s Paradox

    Barry O’Reilly

    An introduction to philosophy for software engineers and architects that will help them understand their design process. This book helps to answer the question “Why are we like this?”.

  • System 3: Towards Fluent Autonomy

    Hani Al-Shater

    What could a mighty billion-parameter reasoning machine learn from a camel trying to touch its ear with its tongue? From a cup of coffee? From deleting your entire codebase while you sleep? More than you’d think. And less than you’d hope. Today’s AI is brilliant structure without grounding—a hollow genius. We chase smarter models but ignore the architecture they need. This book is about building that missing layer: the trust chains and systems that turn raw intelligence into reliable autonomy. For builders ready to move beyond prompts.Watch agents solve unsolvable problems. Learn to think in trust chains. Start here.

  • Be a Learning Machine

    Alberto Souza

    You’ll just need the Five Essential Elements of Learning Through five essential elements, you’ll gain the ability to learn anything deeply—no matter how complex the subject. These five pillars of effective learning will become lifelong tools, guiding you every time you set out to truly master new knowledge and retain it permanently. If you're ready to stop passively consuming information and start truly mastering it, this book is for you.

  • Mastering Modern Time Series Forecasting

    Valery Manokhin

    Mastering Modern Time Series Forecasting is your all-in-one guide to building real-world forecasting systems that work — from classical stats to deep learning and beyond. Whether you're modeling retail demand or energy loads, this book gives you the tools, intuition, and code to go from zero to production. You'll cover ARIMA, ML, deep nets, transformers, and even the rise of FTSMs (Foundational Time Series Models).

    Owen Ou

    Skip the black-box frameworks. Build a production-grade AI coding agent from scratch in pure Python—cloud or local, tested with pytest, under 700 lines.

  • Functional programming in Modern Java

    Jitin Kayyala

    Write code that you can understand without holding the entire system in your head. This book shows you how Java's modern functional features—records, sealed types, lambdas, streams—combine into a powerful approach to design. You'll learn: • How to eliminate race conditions without synchronized blocks • How to write tests that test business logic, not mock frameworks • How to compose complex behaviors from simple, reusable functions • How to manage deeply nested immutable data without boilerplate • How to adopt functional patterns incrementally in existing codebases Written for working developers. Filled with production-ready code examples.

  • Logic for Programmers

    Hillel Wayne

    Logic is the most important branch of math to software engineering. Knowing logic opens up a vast world of development techniques, from everyday tricks of the trade to exotic tools for cracking impossible tasks. This book teaches the basics of logic and nine special logic-powered techniques: property testing, decision tables, constraint solving, and more. Over 50 exercises are provided to help readers master the material. No prior math background required!

Frequently Asked Questions about Reader Memberships and Credits

This is the FAQ for Leanpub Reader Memberships. If you're looking to learn more about Author Memberships, please see the Author Memberships page.

If you can't find what you're looking for below, chances are the answer is in our amazing Help Center which has hundreds of carefully-written articles and a number of lovingly-created videos answering the questions we've been asked over the years. Or, email our support team and one of us will get back to you.

    • Do I need a Reader Membership to buy books or courses on Leanpub?

      No! You can always buy Leanpub books or courses with money, without having a Reader Membership.

    • What are Leanpub Memberships?

      Every Leanpub user can read and write on Leanpub. You can buy books and courses, build your Leanpub library, take courses, and even create your own books or courses. You can create books by writing in your browser or by uploading your own files, and you can create courses by writing in your browser. Leanpub also offers optional paid Memberships that give you additional capabilities. Author Memberships provide premium publishing and writing features. Reader Memberships provide access to about 2,000 “Free With Membership” books, plus book and course credits you can use toward purchasing any Leanpub books or courses.

    • What is a Reader Membership?

      A Reader Membership is a paid subscription that gives you access to about 2,000 Free With Membership books, plus book and course credits you can use to purchase Leanpub books and courses. Membership is optional: you can read and buy books on Leanpub without subscribing.

    • Does Leanpub have a free Reader Membership?

      No. Every Leanpub user can read and buy books, but a Reader Membership is always a paid subscription that provides additional reading benefits. If you have not paid for a Reader Membership, you simply do not have one. A Reader Membership is always a paid subscription.

    • What are the benefits of the different levels of Reader Membership?

      All Reader Memberships give you access to about 2000 books that are Free With Membership. Our Light, Standard, Pro, and Max Reader Memberships all come with book credits, with higher levels including more credits. Our Pro and Max Reader Memberships also come with course credits. Our Legacy Reader Membership (no longer offered for sale) does not include credits, only access to the Free With Membership books. All Reader Memberships allow you to purchase additional book and course credits.

    • Can I buy Book Credits or Course Credits without a Reader Membership?

      No. You need a Reader Membership to buy Book Credits or Course Credits. You can always buy Leanpub books or courses with money without having a Reader Membership. Any Reader Membership—including the currently offered Light, Standard, Pro, and Max plans, as well as the no-longer-offered Legacy Reader Membership—lets you purchase additional credits.

    • Do Leanpub Users Have an Author Membership or Reader Membership by Default?

      Leanpub users do not have an Author Membership or a Reader Membership by default. Membership always refers to a paid subscription that adds extra benefits on top of what every Leanpub user can already do. This approach keeps things simple: all users can read, buy, and write on Leanpub, and Memberships are optional paid upgrades that unlock more value. If you don’t have a Membership, you still have full access to the standard reading and writing capabilities of Leanpub. If you choose to subscribe, you get a clear set of extra features tied to your Membership type.

    • Are reader and author memberships different?

      Every Leanpub user can have two memberships: a Reader Membership and an Author Membership. This FAQ explains the Reader Memberships; there is an author FAQ in the Author Memberships section. A Reader Membership affects your features as a Leanpub reader, and the Author Membership affects your features as a Leanpub author.

    • Why would I subscribe to a Reader Membership?

      A Reader Membership gives you access to about 2000 books which are Free With Membership, along with book credits you can use to buy Leanpub books and course credits you can use to buy Leanpub courses. Your membership also helps support Leanpub authors through our Royalty Pool, and it gives you the convenience of buying books and courses instantly with credits. Different Reader Membership levels include different amounts of book and course credits.

    • What books are free with a Reader Membership?

      There are about 2000 books which are Free With Membership. You can search them by going to the Store in the top menu, choosing the Books submenu, and changing the filter from Bestsellers Last Week to Free With Membership.

    • Are there any books which are free without a Reader Membership?

      Yes! You can search them by going to the Store in the top menu, choosing the Books submenu, and changing the filter from Bestsellers Last Week to Free For Everyone. Any reader, including those without a Reader Membership, can read these books for free.

    • How do I search both Free For Everyone and Free With Membership books?

      You can search for all free books by going to the Store in the top menu, choosing the Books submenu, and changing the filter from Bestsellers Last Week to Free Minimum Price. This search includes books which are Free With Membership or Free For Everyone.

    • How does my paid Reader Membership support Leanpub authors?

      Most of the cost of the paid Reader Memberships goes toward paying for the credits that you get. Leanpub authors earn excellent royalties from those credit purchases, as you'll see below. However, we also pay into a Royalty Pool to support the authors of the books you get which are Free With Membership. We've paid thousands of dollars of Royalty Pool earnings already, and we're just getting started. The amount that is paid into the Royalty Pool is $2.50/month for a paid Monthly Reader Membership, and $9.50/year for a paid Annual Reader Membership. This amount is the same regardless of which Reader Membership you subscribe to. (This matches the amounts that the Legacy Reader Memberships contribute to the Royalty Pool.)

    • Why get a Reader Membership?

      A Reader Membership gives you book credits and course credits, typically at a discount to their a la carte price. These credits can be used toward buying any book or course on Leanpub, sometimes at a discount to the cash price. Also, it's easier to pay with credits than with money: just click a button! You also get free access to about 2000 books which are Free With Membership. Your paid Reader Membership helps support Leanpub authors through the Royalty Pool, as explained above. Finally, your paid Reader Membership helps us build a better Leanpub for our authors and our readers!

    • What are book credits and course credits?

      One or more book credits can be used to purchase ANY Leanpub book, and one or more course credits can be used to purchase ANY Leanpub course. Every Leanpub book and course has a price in credits listed on its store page. When you use credits to purchase a book or course, you do not pay anything extra. (You pay any taxes on credits when buying the credits themselves.) Most Leanpub books cost either 1 or 2 book credits, and most Leanpub courses cost 1 course credit.

    • Why are book credits and course credits different?

      There are two reasons: (1) books are typically much cheaper than courses, and (2) book credits and course credits need to be taxed differently in the EU and UK. More about taxes below.

    • How can I get book credits or course credits?

      You can get credits when your Light, Standard, Pro, or Max Reader Membership subscription renews, either monthly or annually. You can also buy additional credits at any time from the Buy Credits page.

    • Why buy extra book credits or course credits?

      We have different levels of paid Reader Memberships that we currently sell, which come with different numbers of book credits and course credits. However, if you need extra credits, you can buy them easily on the Buy Credits page. This way, you can get the credits you need without changing your membership level, and have the convenience of shopping with credits instead of money. These credits are just like the book or course credits you get with your paid Reader Membership, and can be used toward buying any book or course on Leanpub.

    • Can I use my royalties to buy book credits or course credits?

      Yes, as long as you have a Reader Membership! Just add the credits to the shopping cart on the Buy Credits page, and at checkout choose to pay with your Leanpub royalties, credit card or PayPal.

    • Can I use my royalties to pay for a Reader Membership?

      No. Since all Reader Memberships we currently sell include credits, we no longer offer a Lifetime option for any of these Reader Memberships. So, because of this, you cannot use royalties. Making royalty purchases work for subscription payments would be too complex to justify doing.

    • What is a Legacy Reader Membership? What happened to the old Reader Membership?

      We used to sell just one type of Reader Membership. We are now calling this the Legacy Reader Membership. The Legacy Reader Membership used to cost $4.99 per month, $19 per year, or $99 lifetime. (These memberships paid $2.50, $9.50 or $49.50 into the Royalty Pool, respectively.) The Legacy Reader Membership provided free access to about 2000 books which are Free With Membership, and did not come with any credits for premium books or courses. The Legacy Reader Membership is no longer available for sale. We discontinued the Legacy Reader Membership when we introduced the new paid Reader Memberships with credits.

    • I have a Legacy Reader Membership. What happens to it?

      If you currently have a Legacy Reader Membership, nothing changes. Your price does not increase, and the membership benefits do not change. This is true if you have a Monthly, Annual or Lifetime Legacy Reader Membership. Your membership continues to give you free access to about 2000 books which are Free With Membership. It does not come with any credits for premium books or courses, of course, because those credits were never part of that membership.

    • If I upgrade to one of the other Reader Memberships, what happens to my Legacy Reader Membership?

      If you upgrade from a Monthly or Annual Legacy Reader Membership, you cannot downgrade back to the Legacy Reader Membership. If you upgrade from a Lifetime Legacy Reader Membership, you will automatically downgrade back to the Lifetime Legacy Reader Membership if your upgraded Reader Membership expires or if you cancel it.

    • How do my Leanpub credit card, PayPal or royalty purchases support Leanpub authors?

      For credit card, PayPal or royalty purchases, we pay 80% royalties on books and courses priced at $7.99 and up. Below $7.99, we pay 80% minus 50 cents. So, Leanpub authors earn $3.50 from a $5 sale, $8 from a $10 sale, $16 from a $20 sale, and $24 from a $30 sale. You'd be surprised how many people buy $20 and $30 ebooks! Similarly, on a $129 course sale, the author earns $103.20. That adds up fast. Leanpub was founded by authors, and exists to serve our authors.

    • How are the credit prices of books and courses calculated?

      To calculate the credit price, by default we divide the the minimum price of a book by $25, or the minimum price of a course by $125, and round up. So, a $19 minimum price book costs 1 credit, and a $39 minimum price book costs 2 credits. Similarly, a $99 minimum price course costs 1 credit, and a $249 minimum price course costs 2 credits. Now, this is just the default: authors can choose to price their books and courses at a discount when purchased with credits, so your credits may go even further! (For example, an author might choose to price a $29 or $39 book at 1 book credit, or a $129 or $149 course at 1 course credit.)

    • How do taxes like VAT work for book credits and course credits?

      Book credits are taxed like Leanpub ebooks, and course credits are taxed like Leanpub courses. For our EU and UK customers, this means that if your country has a discounted rate for ebooks, then the book credits will have this same discounted rate. This is correct because a book credit can only be used to purchase a Leanpub ebook, so it is a single-purpose voucher whose VAT rate can be calculated at the time of purchase. Similarly, a course credit can only be used to purchase a Leanpub course, so it is also a single-purpose voucher that gets the standard non-discounted VAT rate that applies to Leanpub courses. For example, in the UK, ebooks are taxed at 0% VAT, while online courses are taxed at 20% VAT. This is the main reason why we have separate book credits and course credits.

    • Do I still support authors with book credits or course credits?

      Yes! When you use credits to purchase a book or course, the author still earns great royalties. Typically the author earns the same amount of royalties as a minimum nonzero price purchase with a credit card or PayPal. The exact details are shown later on this page. So, you continue to provide excellent support to Leanpub authors when you use book or course credits to make a purchase.

    • How do author royalties work for purchases using book credits or course credits?

      The short answer is that the author typically earns the same royalties they would earn on a minimum nonzero price purchase. The longer answer is that the royalty rate is determined by comparing the credit cash price to the minimum nonzero price, as explained in the questions below.

    • What is the credit cash price?

      The credit cash price is determined by calculating the cash equivalent of the credit price. The credit price is the number of book or course credits needed to purchase the book or course. To calculate the credit cash price, the credit price is multiplied by $25 for each book credit and by $125 for each course credit, regardless of their actual purchase cost. (With Leanpub Reader Memberships, book and course credits are typically acquired at a discount.) For example, if a book has a 2 book credit price, the credit cash price is $50 (as 2 book credits x $25 per book credit = $50). Similarly, if a course has a 1 course credit price, the credit cash price is $125 (as 1 course credit x $125 per course credit = $125). The credit cash price is then compared to the minimum nonzero price to determine author royalties, as explained in the cases below.

    • What is the minimum nonzero price?

      The minimum nonzero price is set by the author, and is the minimum non-free price that a reader can pay for a book or course. Leanpub books and courses can also be available for free, either Free With Membership or Free For Everyone. However, even in these cases, there is also a minimum non-free price which the author sets, and which any reader can pay to buy the book or course. This price is the minimum nonzero price. The minimum nonzero price is the smallest amount of money above $0 that a reader can pay for the book or course. The minimum nonzero price affects how author royalties work for purchases using credits, as discussed below.

    • What are the author royalties for purchases where the credit cash price is lower than the minimum nonzero price?

      If a reader is using credits to buy a book or course, and the credit cash price is lower than the minimum nonzero price, the author earns 80% royalties on the credit cash price. So, in this case, the author earns $20 per book credit used (as $20 is 80% of the $25 book credit cash price), or $100 per course credit used (as $100 is 80% of the $125 course credit cash price). For example, if a book has a $29 minimum nonzero price and a 1 book credit price, the author earns $20 (which is 80% of $25) when a reader purchases the book with 1 book credit. Similarly, if a course has a $129 minimum nonzero price and a 1 course credit price, the author earns $100 (which is 80% of $125) when a reader purchases the course with 1 course credit. For us, this is the ideal scenario: the reader gets a slight discount, and the author still earns excellent royalties!

    • What are the author royalties for purchases where the credit cash price is greater than or equal to the minimum nonzero price?

      If a reader is using credits to buy a book or course, and the credit cash price is greater than or equal to the minimum nonzero price of that book or course, the purchase is treated as a minimum nonzero price purchase. For example, if a book has a $19 minimum nonzero price and a 1 book credit price, the author earns $15.20 (which is 80% of $19) when a reader purchases the book with 1 book credit. Or, if a book has a $39 minimum nonzero price and a 2 book credit price, the author earns $31.20 (which is 80% of $39) when a reader purchases the book with 2 book credits. Similarly, if a course has a $99 minimum nonzero price and a 1 course credit price, the author earns $79.20 (which is 80% of $99) when a reader purchases the course with 1 course credit. Or, if a course has a $249 minimum nonzero price and a 2 course credit price, the author earns $199.20 (which is 80% of $249) when a reader purchases the course with 2 course credits. Finally, if a book has a $5 minimum nonzero price and a 1 book credit price, the author earns $3.50 (which is 80% of $5 minus 50 cents) when a reader purchases the book with 1 book credit. (In this case, however, the reader typically would be better off just using money to make the $5 purchase, of course, so we don't expect this to be a common use case!) In all of these cases, the author earns the same royalties as they would on a minimum nonzero price purchase.
