Correcting a misunderstanding, zlibrary, which is mentioned in almost every answer, is not the first choice!!!

Seniors or School Group Forums
The advantage of seniors or school group forums is that they have the highest fit with the university textbooks you need. As long as you still use their textbooks, you can almost always find the electronic version you need.
After all, the problem you encounter is not a special case, but a common problem encountered by several generations, or even more than a dozen generations of seniors. In the inheritance of these dozen generations, someone may have already packaged the electronic books you need for you, and even included precious resources such as past years' papers and notes.
Show the resources of our school group.


Of course, there are also cases where new textbooks are just changed in your session. At this time, there are no e-book resources on websites such as zlib (no one scans and uploads). At this time, you can also ask for help from seniors or classmates of the same level. They may help you scan a book.
Don't ask me why I know, because I have already helped my classmates scan two or three books (there are no electronic versions on zlib and annas).
In this way, you will basically get more than half of the electronic textbooks you need.
Various QQ groups, WeChat groups or forums related to your major
The principle is basically the same as the previous method, relying on the inheritance of predecessors and everyone's help.
These QQ groups, WeChat groups or forums have a probability of bursting out high-quality, uncirculated, first-hand e-books.
For example, the following books have been repaired and enhanced by experts, including but not limited to adding bookmarks, OCR, enhanced scanning, missing page repair, etc.

And these are resources that are difficult to find or simply not available on zlib or various websites!
Major E-book Resource Websites
In terms of resource richness, Anna's Archive is the first choice. It can be said that zlibrary, which is mentioned in almost every answer, is just a subset of it!!!
Because Anna's Archive has "liberated" the collection data of zlibrary.

The following are recommended resource websites, all of which have been tested by me.
- Anna's Archive
- Z-Library – The world's largest e-library. Freely access knowledge and culture.
- Chinese Text Project
- Shuge
Among them, Anna's Archive has the richest resources, but downloading requires queuing, so it is not the first choice. And Z-Library – The world's largest e-library. Freely access knowledge and culture. has rich enough resources, convenient download, and beautiful interface, so it should be the first choice.
The subsequent Chinese Text Project and Shuge focus on two subdivided fields of Chinese philosophical books and Chinese ancient books, and are the first choice for books in the field.
Network Disk Channels
You can use Sousoupan - Pansousou - Network Disk Resource Search Engine to aggregate search resources of major network disks.
BT Channels
Since BT websites are easy to hang, a BT navigation station is given here.
BT Ant Magnet | A magnetic search navigation website that understands you
Search Engine
The most convenient method, but the quality is not guaranteed.

In search engines, you can find resources from various websites mentioned above, as well as resources from platforms such as Zhihu, Xiaohongshu, Weibo, github, personal homepages, and various forums.
However, the quality of these resources cannot be guaranteed, and paid downloads may be required.
Paid Channels
Including but not limited to:
- Various e-commerce platforms, such as Taobao
- Various second-hand trading platforms, such as Xianyu
This may be the last resort for the poor, or the first choice for the rich.
E-book No Bookmarks?
If the e-book has no bookmarks, in addition to trying to find another e-book with bookmarks, you can also manually add bookmarks yourself.
Refer to the answer I wrote before.

Besides Textbooks, Want to Read Manga?
Learning certainly requires a combination of work and rest. Why not read manga to take a break.
For methods on how to get manga resources, please refer to my previous answer.
