1. Different binding methods 

Hardcover book 

The spine is bonded with eco-friendly hot melt adhesive between the inner pages and the cover. There are no needles or threads involved. The whole thing is smooth and simple, commonly used for exercise books, notebooks and picture albums. 

Paperback edition 

The pages are sewn together using cotton thread and lockstitching. The spine is lined with stitching, making it more sturdy. This type of binding is commonly found on thick books, mistake correction books, and high-quality note-taking books. 

II. Balanced Writing Experience 

Hardcover: It is very difficult to fully lay flat at a 180° angle. When writing on the middle cross-page, it will get stuck against the spine and be uncomfortable to hold. It is also prone to cracking when forcibly opened. 

Stationary format: It can be laid flat and spread out at 180°, allowing for unrestricted writing and drawing across pages, making the writing experience more comfortable. 

III. Durability and Stability 

Hardcover: If repeatedly folded and pulled over a long period of time, it is prone to losing glue, pages falling off, and the spine cracking. Its service life is generally not long. 

Stationary binding: Sewn securely with thread, it is less likely to separate pages or fall off, more resistant to folding, and has greater durability, making it suitable for long-term and repeated use. 

IV. Appearance and Thickness 

Hardcover edition: The spine is thin and simple, the overall design is elegant and simple, with a wide variety of styles and reasonable prices. 

Hardcover: The spine is slightly thicker, and the stitching design can be seen. It has a better texture and a higher grade, but the price is slightly higher. 

V. Applicable Scenarios 

Hardcover books: Primary school students' exercise books, short-term practice books, lightweight notebooks, with high cost-effectiveness. 

Stationery format: Error correction notebooks, handbooks, drawing books, long-term record books, frequently rewritten books. 

VI. Summary of Purchase Choices 

Daily short-term practice exercises and class assignments: Binding them into a hardcover book is a cost-effective solution that is sufficient. 

For long-term use, frequent page-crossing writing, and the need for durability without page-tearing: choose the hardcover version.
