If the code of the library is accessed during the build of the invoking program, then the library is called a static library. A librarian is a person who works in a library. Some programming languages may use a feature called smart linking whereby the linker is aware of or integrated with the compiler, such that the linker knows how external references are used, and code in a library that is never actually used, even though internally referenced, can be discarded from the compiled application. This approach is commonly used in a distributed architecture that makes heavy use of such remote calls, notably client-server systems and application servers such as Enterprise JavaBeans. DCOM, a modified version of COM, supports remote access. This is a side-effect of one of OOP's main advantages, inheritance, which means that parts of the complete definition of any method may be in different places. Examples include IBM's System Object Model (SOM/DSOM), Sun Microsystems' Distributed Objects Everywhere (DOE), NeXT's Portable Distributed Objects (PDO), Digital's ObjectBroker, Microsoft's Component Object Model (COM/DCOM), and any number of CORBA-based systems. Objects can consist of digitized content like print or photographs, as well as originally produced digital content like word processor files or social media posts.  Physical books were relocated to classrooms or donated to developing countries.  In a study conducted by the article's, "Millennials and technology: putting suppositions to the test in an academic library", authors, Pascal Lupien and Randy Oldham, reveal that "our students do use the library in large numbers, and that they appear to understand that they must use a variety of resources, including academic sources, to conduct research". This allows position-dependent code, but places no significant restrictions on where code can be placed or how it can be shared. These may include configuration data, documentation, help data, message templates, pre-written code and subroutines, classes, values or type specifications. Since most computers can do at most one or two things at one time, this is generally done via time-sharing, which means that each program uses a share of the computer's time to execute. The desktop contains icons as shortcuts - clicking on these icons opens up the file, folder, or application that they stand for. In computer science, a library is a collection of non-volatile resources used by computer programs, often for software development. They are used by aspect-oriented programming, some data access frameworks, and for testing to generate dynamic proxy objects.  When explaining the rationale for budget cuts, officials often cite the rise of new technologies and the availability of alternative sources of information.  Library functions, services and usage are changing so rapidly that it is difficult to establish standards or measures of value.  A similar poll of Britons, conducted in 2010, stated that 67 percent had visited a library within the last year.  The number of school librarians has declined, with many school librarians being laid off or assigned to other teaching duties. Secondly, it allows the executables also to be used as shared libraries, if they have a symbol table. For example, a framework called MyFramework would be implemented in a bundle called MyFramework.framework, with MyFramework.framework/MyFramework being either the dynamically linked library file or being a symlink to the dynamically linked library file in MyFramework.framework/Versions/Current/MyFramework. Most libraries are moving existing staff into information positions instead of employing new information custodians, making a developing interest for expert improvement opportunities. This optimization is known as prebinding in macOS and prelinking in Linux. , With public funding declining for both libraries and schools, school libraries face severe economic troubles. With changes on the horizon, the organizations that monitor academic library statistics are seeking new ways to assess value and impact. In general, relocation cannot be done to individual libraries themselves because the addresses in memory may vary depending on the program using them and other libraries they are combined with. These systems make sure, by various tricks like pre-mapping the address space and reserving slots for each shared library, that code has a great probability of being shared.  Public library patrons value access to printed books and traditional reference services. Yet, it shares their mutual properties: software consists of clearly-defined instructions that upon execution, instructs hardware to perform the tasks for which it is designed. Position-independent code avoids references to absolute addresses and therefore does not require relocation.
