Help us build the world's largest paper book library!

Sep 09, 2023

We're excited to announce the launch of a project we've been hinting about in our previous blog post: our book exchange initiative. This project has grown beyond our initial concept of a simple book exchange and has evolved into a global library of paper books. Our ultimate goal is to connect readers worldwide and make literature accessible to everyone, regardless of location or financial constraints.

The project will be launched in several stages:
In the current (first) stage, we start gathering books over the world. If you have books that you no longer need or simply wish to share your literary collection, please send them to our designated literary hubs, known as Z-Points. There, we carefully store books, digitize (if the laws of a particular country allow), and send them to users and educational institutions in need.

Сall to sign the petition in support of Z-Library

Aug 15, 2023


As you may have noticed, our library has been through significant updates in the last few months. It's been a time of growth and evolution, as we've worked tirelessly to improve library accessibility and service stability. However, behind the scenes, we're still under tremendous pressure from the FBI.

As you may know, in November 2022, two alleged participants in the project were arrested in Argentina at the request of the United States and still remain imprisoned for almost a year. Their detention occurred without compliance with legal norms and with numerous procedural violations. For example, a court sanction for arrest has been issued after the arrest. This situation has greatly affected the operation and functionality of the Z-Library.

Today, we are calling on you, our community, to join us in our fight for the Z-Library project. This project represents more than just a platform; it's a gateway to knowledge for people all over the world.

We are launching a petition to restore access to Z-Library and stop the illegal criminal prosecution. Your signature can make a world of difference.

Introducing Desktop launcher and updated Android app, share buttons, news channels

Jun 22, 2023

Z-Library desktop launcher

Our team continues working on improving the accessibility to our library, and we now want to introduce the alpha version of our desktop launcher for Windows, macOS and Linux. This launcher will save you the trouble of searching for a working website link, as it will handle everything for you. Additionally, the application can operate over the TOR network, so you will always be able to use the library while maintaining your privacy. As a small bonus, all users accessing the library through the desktop application will get a one-month premium membership and doubled daily download limit (the period starts from the first app launch)!

Please note that since this is an alpha version, the application may not run on your computer. If you encounter any issues, feel free to contact our support team, and we will assist you.

⚠️ Upon the first launch of the application, you may encounter a warning message regarding an unverified developer. This is expected, as we don't yet have a Developer account on these platforms.

The Z-Access page, Share button, return of the Preview option, and stories behind Z-Library

May 20, 2023

Dear Z-Library community,

We are excited to share with you some news from Z-Library. As always, our team is working hard to improve our service and make it more user-friendly and convenient. In this blog post, we will introduce you to several new features and improvements that we have recently added to our platform. So, let's dive in and explore what's new at Z-Library!

Z-Access Page

We have created a special page called Z-Access that provides users with all possible access points to our library, including personal domains, Android app, Telegram bot, magic email, and other useful links. You can find it in the menu or on your profile page.

Worldwide Statistics: How Students and Educators Use Z-Library

Apr 27, 2023

It's no secret that the most active users of our library are students and staff from various universities. We wanted to learn more about this and have collected statistics showing which educational institutions use Z-Library and how they use it. How did we separate one university user from another? For data collection and analysis, we decided to rely on the domain zone where users' email addresses are located. For example, an email like "*" allows us to assume with a high degree of confidence that this is an employee or student of the University of Toronto.

During the collection of statistics, we discovered that Z-Library is currently used by more than 600,000 students and teachers from over 30,000 educational institutions (universities, colleges, and schools) worldwide! These values, and the numbers in the graphs below are a low estimate since not all users give their university email addresses when registering. However, the obtained statistics should be relatively accurate. Also, due to the large number of users from China, we decided to combine the largest universities of this country into one line.

So, let's start with the general statistics. In which countries do university students and staff use Z-Library most actively? (We highlighted Taiwan due to the significant number of our users located there. There are no political reasons involved).

Spring Fundraising 2023 results, magic email address and book swap service

Apr 04, 2023

Dear Z-Library Community,

We are happy to announce that Spring Fundraising 2023 has been successfully completed, and we have raised all the necessary funds to develop our project. With your support we are able to continue our work on improving Z-Library, thank you very much for your help! We aim to provide access to the scientific literature and help educate people around the world. We would like to express our gratitude to everyone who has contributed to our library – your support motivates us to keep working on the project in these difficult times.

And now let's speak of other important news. As you know, some of our domains remain blocked in several countries. Today, we offer the possibility of creating an account or restoring access to an existing one through a special email address. How does it work? Just send any letter from your mailbox to our magic email address, and you will receive your personal access to Z-Library in the auto-generated letter within 3–5 minutes. So simple!

Back to the Clearnet: personal domains

Z-Recommend, say “Thank you” option, new menu, booklist comments and plans for 2023

Jan 26, 2023

Dear Z-Library community,

As you may know, in November 2022, as ordered by the US secret service, almost all the public domains of the library were blocked, and the inner infrastructure of the project suffered some substantial damage, too. Today, we are still under unprecedented pressure. At the moment, Z-Library is going through the hardest times in all the 14 years of its existence. The library might work with interruptions, and we ask you to be patient. Be sure - we are doing everything possible to ensure free access to knowledge for millions of people across the globe, and we expect you to help us with that and to support us.

But despite all the difficulties, the library continues to function and develop! We have recently introduced several important features - the new recommendations section, comments to booklists, the new web-site menu, and also now you can thank the users who made the books appear online. Now, let us speak about each of those and our plans for 2023.

A few words about the events of November 2022

Nov 18, 2022
As many of you know, on November 3rd most of our domains were seized and some our servers were suspended by the United States Department of Justice and Federal Bureau of Investigation. In addition, on November 16 the United States Department of Justice published the indictment against two citizens of Russia, Anton and Valeria. They are accused of criminal copyright infringement, wire fraud and money laundering to operate the Z-Library.

We refrain commenting on the alleged Anton and Valeria involvement in the Z-Library project and the charges against them. We are very sorry they are arrested. We also regret that some authors have suffered because of Z-Library and ask for their forgiveness. We do our best to respond to all complaints about files hosted in our library if it violates author's rights.

We see the resonance recent events caused, we see how many people support and believe in Z-Library. Thank you for your support, it is extremely valuable to us. Thank you for each donation you make. You are the ones who making the existence of the Z-Library possible. We believe the knowledge and cultural heritage of mankind should be accessible to all people around the world, regardless of their wealth, social status, nationality, citizenship, etc. This is the only purpose Z-Library is made for.

My makeup may be flaking
But my smile still stays on

Summer updates: some changes for Kindle option, improved design, Bulgarian language and over 50k new books

Aug 10, 2022

Z-Library is a library that is open twenty-four hours a day, seven days a week. Like our readers, Zlibrary strives to become better, and that's why we've made a number of upgrades.

We want our users to focus on reading, not on technical things. Therefore, we have increased the size of files that can be sent, the limit is now 45 MB and performance of full-text search became higher—search results appear faster. We increased displayed books limit from 500 to 1000 books for premium users only.

As you know, Amazon will stop supporting MOBI files for sending to Kindle at the end of the month. It will be replaced by EPUB. Until that happens, we recommend using MOBI, as EPUB is still a work in progress. While the choice is yours, you can also send EPUB files to Kindle, Zlibrary already has this feature.

Top Moderators, new languages available, moderation section for users and Android app update

Jun 10, 2022

Hello Z-Library community,

We're back to tell you what's new here. As we mentioned in the previous blog post, we have decided to focus on improving the quality of our book collection and have introduced moderation of uploaded books. We were glad to know there are many users who want to become a moderator and ready to spend their time helping the library. Thank you so much! Furthermore, at the request of some moderators, we have added a “Top Moderators” nomination to the Top Z-Librarians page. Similar to uploaders and editors, the most active moderators will get the bonuses.

Spring fundraising, Moderators, updated book page, Z-Alerts & book requests regulations, language filter for booklists, and more

Apr 01, 2022


It's been a long time since our last post. What’s new? Big things, actually. Our Team has been busy making upgrades for the library.

On April 1, we successfully completed our spring fundraiser. Our team would like wholeheartedly to thank all the users who participated (and those who couldn't support us but really wanted to) in the spring fundraiser. We have also considered all of your wishes and suggestions to improve the project. Thank you very much!

Do you know that we have recently passed the 10 million-book upload barrier?! Over the past few years, our book collection has grown significantly thanks to you, our users. To improve the quality of the collection, we have launched a moderation section for uploaded books and invited our trusted users to become moderators. Book moderation will greatly reduce the number of spam, junk files and books with incorrect information. Here's a list of the top ones who have moderated most of the books:

Dear Community

Fundraising results, new “Add to Favorites”, Public Booklists, Android App, updated category filter, and more

Oct 19, 2021

Hello, ZLibrary Community!

We would like to begin by congratulating everyone on a successful fundraising campaign! We are grateful to you for supporting our project despite the difficult last 2 years. Your feedback and suggestions also help the project to develop in the right direction. Thank you all!

Meanwhile, our development team doesn’t just sit around and the new updates are proof of that. No doubt many of you have already noticed the disappearance of the “Saved books” and the “Save for later” button. But don't worry, the feature isn't gone, we have just improved it and now you can save books to Favorites by using the heart button under the book title. We recommend adding tags, this will significantly help you organize your Favorites and quickly sort books. Next to the "Add to Favorites" button, there is another useful button that allows you to add a book to your booklist in one click.

Book requests search, one-click download, booklists and other visual improvements

Aug 23, 2021

Hello, Zlibrary community!

Time for other updates about our library. Since our last blog post, we've spent more time on technical improvements than visual changes, but we still have a lot to share with you.

The long-awaited book requests search option. Now you can find a request by ISBN, book title, author, or publisher.

We also brushed up the form of adding new requests and fixed the flaws of the previous version.

NEW category system, profile page, search results page, and book covers

Jun 15, 2021

Dear Zlibrary community,

We continue to inform you about new features on our site. As we've already mentioned in the previous post, we're planning to refresh the design of some pages/elements and improve the functionality.

Let's start with the preview of our new category system, a feature that we've spent a lot of time and resources on. If you're not already familiar with it, be sure to check it now. In a few words, we have divided the categories into Fiction / Non-Fiction, fundamentally revised the past categories, and added new ones. At the moment most of the books don't have categories. Unfortunately, we can't do this automatically due to technical limitations, so if you know which category a particular book belongs to, please spend a minute to put in a category using the option "Suggest a correction", thus you will help other users to find the book quickly.

Please note that some subcategories may not be displayed on the category page, because they don’t include any books. As soon as at least one book appears there, that subcategory will immediately become available. If you consider that a category/subcategory is missing, our Support Team is always open to your suggestions :)

The results of fundraising, book rating, and a new page of download history

May 10, 2021

Dear Zlibrary Community,

We have some good news to share! The latest fundraising campaign was successfully completed, with about 200 countries participating! This is a sign to us of how our library has grown over the past few years, and all because of you. Thank you for putting up with bugs that come up from time to time, for reporting on errors with lightning speed, and for actively participating in the “life” of our library. Back in 2009, no one thought this project would grow into something big. Your touching feedbacks, which you send to us and post under the blog entry, give us a sense that we've come all this way for a reason. Thank you all!

So let's finally talk about the new features. We've recently implemented a feature to rate the plot of the book and the quality of the file. We hope this will help you choose the highest-quality version of the book, and we will be able to remove books with a low-quality rating in the future. This feature is located on the book page, just under the "author". Find it? You may wonder why two different colored scores are displayed. The orange score is for the plot of the book and the green one is for the quality of the file.

Please note: any user can rate the plot, but only users who downloaded the book can rate the quality.

New options: "book requests" and save your search filters

Feb 15, 2021

Hello booklovers,

Zlibrary team is on the air and we’re going to share the news that has happened since our last “meeting”.

Finally, the long-awaited "Book request" option is now available on our website! And from now on, you don't have to write us an email or a comment asking to add books, you can just use this option. All you need to know is an ISBN of the book and our system will automatically fill in the necessary information.

Please make sure that we don't have the book in the library before creating a request. If the book is available but you need a different file format, you won't be able to request it.

Besides subscribing to a book request (using the "Tracking" button), you can also set up a notification: either by email or through your account. Later we will make a search through book requests and a filter by category.

Telegram bot, updated profile menu, Booklists and more

Dec 27, 2020

We know 2020 isn’t shaping up to be a good year, but we’re still trying to make it better for our ZLibrary family. And we are excited to announce the last updates of this year.

We have finally launched our own Telegram bot! To access it, please use the Telegram icon in a footer, or visit the Edit Profile page. Using this bot you can download extra books in addition to your daily limit on the website. However, if you want to use options such as File conversion, Send-to-email, Send-to-Kindle, Send-to-Google Drive or download a book that is more than 50 MB, you will need to proceed to the website version. There you can also find the latest information about available domains by using the command /weblink. Just hurry up to install our Telegram bot and enjoy the books for the upcoming holidays! ✨

Before we move on to the second key feature, we want to draw your attention to the redesigned menu. We've separated your profile menu sections from the general ones to make it easier to navigate through the menu.

Black Friday promotion, reward system, tabular view, quick search field and more

Nov 22, 2020

Dear booklovers!

Firstly we would like to announce that we are launching the Black Friday promotion from today (November 22nd) until December 1st. During this period you will receive unlimited downloads (or 999 downloads) for 31 days for any donation. Don’t miss the chance to enjoy the collection of your favourite books on Christmas days!

We also want to share with you the exciting news: we have redesigned the Top Z-Librarians page and launched a reward system for the most active users! Users will be rewarded according to the rating for a week and a month. At the moment the top of last week: Beowulf, jourmager and the top of October: Big Bang, umberto, jourmager (editors) and FRANCESCO, Glos, AvidReader (uploaders) have already received their awards. We also plan to reward other users who have actively participated in the life of our library (yes, we are talking about those heroes from the Overall rating). Thank you so much for your contribution! Our book collection wouldn’t be the same without your hard work. Do you want to be one of them? You can check the rules here.

September fundraising, website internationalization, new logo and other updates

Oct 02, 2020

Hello, ZLibrarians!

We would like to share the good news: the September fundraising campaign has been successfully completed. As you know every September and March we launch additional fundraising for the project maintenance and development. And thanks to your active support we are achieving our goals and moving forward! You are the best! We also know that many users failed to donate, but they really wanted to support us. Thank you very much for your efforts, we hope that by the next fundraising we will correct this situation.

Have you ever wondered how many languages are there in the world? A few months ago we asked ourselves whether it is convenient for users from different countries to use the English version of the site (the most complete and up-to-date version at that time) and realised that the project needs to be internationalized. So we would like to announce that we are translated into 28 languages now (some languages will be available soon): Arabic, Armenian, Azerbaijani, Bengali, Chinese, English, French, Georgian, German, Greek, Hindi, Indonesian, Italian, Japanese, Korean, Malaysian, Pashto, Polish, Portuguese, Russian, Serbian, Spanish, Telugu, Thai, Turkish, Ukrainian, Urdu, Vietnamese. Hooray! You can try it now by changing the language at the bottom of the page. Please inform us by email If you find any translation mistakes. We’ll be very grateful for your help!

Converting files. We have slightly increased the limit and now the files up to 8 MB are available for conversion. Unfortunately, we can’t increase it more due to the technical limitations :(

Home page, "Mark as downloaded" button and improved book recommendations

Aug 16, 2020

Hello, book lovers!
Zlibrary project team is on the air and today we’re going to tell you about several interesting updates. Let’s go!

Do you know that we have a home page? On this page, you can always find the relevant information about available domains (books and articles) for your region. As soon as you get to the Home page, our system will automatically match an available domain for you. We recommend you to save it to your bookmarks in case any of the site addresses doesn't work. You can also get to this page by clicking on the “ZLibrary Home” button in the upper left corner of the page.

Domains separation, sending to Google Drive, FTP bulk uploader and the new language filter

Jul 02, 2020

Welcome to another update of ZLibrary!

Let's start with the main update of this month: domains separation by region. If you go to you will be automatically redirected to the domain according to your region. Why is this update necessary? The separation into regions will improve the stability and accessibility of the service in the future, as well as the download speed. Don’t worry, books are uploaded equally to all the domains. Since this is a large and complex update the site may not work well sometimes, please report on current issues to our email

We noticed that many users save books to Google Drive and decided to simplify this process: now you can immediately send books to your Google Drive, moreover, they will be saved in the automatically created “Zlibrary” folder. To use this wonderful option, just click on the arrow on the Download button.

Fundraising results, improved mobile version, Your uploads page and mini-survey

Apr 11, 2020

First of all, we would like to congratulate everyone on another successful fundraising campaign! In truth, we did not expect it to be successful, as it fell on such a difficult period for all of us. Even in this situation, a lot of users have supported our project, and we are very grateful for that! Our Team wholeheartedly says Thank you! The funds received will be used to improve the library and I will tell you in confidence, this year we are planning big updates!

Despite the quarantine, we continue working on the improvements. We noticed that many people use the library from their phones and thought about how to improve the mobile version. We will not describe in detail all the changes, but now using the mobile version has become easier and more convenient.

Improved full-text search, spring fundraising campaign and unlimited downloads

Mar 14, 2020

The Covid-2109 pandemic has gripped the world and more and more regions are quarantining: schools, airports, universities, regions, and even whole countries are closing. And if you are currently quarantined at home - make good use of your time with reading books.

March 15 comes soon, and we traditionally run the additional fundraising event. For those who don't know what we are talking about: twice a year (in September and March) we hold an additional fundraising campaign. And if you support us during this period you will get unlimited downloads for 31 days for any donation. Your active support gives strength to our Team and inspires to work. Only thanks to your support, we not only exist but also actively develop. Each donated dollar is not only money for us, but it is also the confidence that you really need our project!

Now we are going to tell what changes have occurred in the Full-text search. What is the Full-text search and how it differs from the usual search? Answers to these questions you will find in our last post. We finally indexed all the articles that we have today. That means 70+ million articles are available in the Full-text search now

Many users have already tested the full-text search on articles and shared their impressions. And according to your numerous wishes, we have implemented two features that will make the search results as relevant to your requests as possible. It is available both for articles and for books. First, we added the ability to filter full-text search results by year, language and file format. Please note that only the filter by year is available for articles.
