Ohjelmistokirjasto, or software library in English, is a collection of pre-written code modules and subroutines that programmers can use to develop software applications more efficiently. These libraries provide ready-made solutions for common programming tasks, saving developers from having to write the same code repeatedly. They can encompass a wide range of functionalities, from basic input/output operations and mathematical calculations to complex tasks like networking, graphics rendering, and database management.

The use of software libraries promotes code reusability, which is a fundamental principle in software engineering. By leveraging existing, tested code, developers can reduce development time, minimize the introduction of errors, and focus on the unique aspects of their specific project. Libraries are often developed and maintained by communities or companies, and they can be general-purpose or specialized for particular programming languages, operating systems, or application domains.

There are typically two main types of software libraries: static and dynamic. Static libraries are linked directly into the executable code of an application during the compilation process. This results in larger executable files but means the application can run without needing the library file to be present on the target system. Dynamic libraries, on the other hand, are loaded into memory when the application is run. This allows multiple applications to share a single copy of the library, leading to smaller executable files and easier updates, but requires the dynamic library file to be available on the system where the application is executed. Understanding and utilizing software libraries is a crucial skill for any software developer.
