The Bliss bibliographic classification (BC) is a library classification system that was created by Henry E. Bliss (1870–1955) and published in four volumes between 1940 and 1953. Although originally devised in the United States, it was more commonly adopted by British libraries. A second edition of the system (BC2) has been in ongoing development in Britain since 1977.
The Dewey Decimal Classification (DDC), colloquially known as the Dewey Decimal System, is a proprietary library classification system which allows new books to be added to a library in their appropriate location based on subject. It was first published in the United States by Melvil Dewey in 1876. Originally described in a 44-page pamphlet, it has been expanded to multiple volumes and revised through 23 major editions, the latest printed in 2011. It is also available in an abridged version suitable for smaller libraries. OCLC, a non-profit cooperative that serves libraries, currently maintains the system and licenses online access to WebDewey, a continuously updated version for catalogers.
The Library of Congress Classification (LCC) is a system of library classification developed by the Library of Congress in the United States, which can be used for shelving books in a library. LCC is mainly used by large research and academic libraries, while most public libraries and small academic libraries used the Dewey Decimal Classification system. The classification was developed by James Hanson, with assistance from Charles Martel, in 1897, while they were working at the Library of Congress. It was designed specifically for the purposes and collection of the Library of Congress to replace the fixed location system developed by Thomas Jefferson.
A library classification is a system of organization of knowledge in which sources are arranged according to the classification scheme and ordered very systematically. Library classifications are a notational system that represents the order of topics in the classification and allows items to be stored in the order of classification. Library classification systems group related materials together, typically arranged as a hierarchical tree structure. A different kind of classification system, called a faceted classification system, is also widely used, which allows the assignment of multiple classifications to an object, enabling the classifications to be ordered in many ways.
George Herbert Putnam was an American librarian. He was the eighth Librarian of Congress from 1899 to 1939. He implemented his vision of a universal collection with strengths in many languages, especially from Europe and Latin America.
Melville Louis Kossuth "Melvil" Dewey was an influential American librarian and educator, inventor of the Dewey Decimal system of library classification, a founder of the Lake Placid Club, and a chief librarian at Columbia University. He was also a founding member of the American Library Association. Although Dewey's contributions to the modern library are widely recognized, his legacy is marred by allegations of sexual harassment, racism, and antisemitism.
A toy or plaything is an object that is used primarily to provide entertainment. Simple examples include toy blocks, board games, and dolls. Toys are often designed for use by children, although many are designed specifically for adults and pets. Toys can provide utilitarian benefits, including physical exercise, cultural awareness, or academic education. Additionally, utilitarian objects, especially those which are no longer needed for their original purpose, can be used as toys. Examples include children building a fort with empty cereal boxes and tissue paper spools, or a toddler playing with a broken TV remote control. The term "toy" can also be used to refer to utilitarian objects purchased for enjoyment rather than need, or for expensive necessities for which a large fraction of the cost represents its ability to provide enjoyment to the owner, such as luxury cars, high-end motorcycles, gaming computers, and flagship smartphones.

Shiyali Ramamrita Ranganathan was a librarian and mathematician from India. His most notable contributions to the field were his five laws of library science and the development of the first major faceted classification system, the colon classification. He is considered to be the father of library science, documentation, and information science in India and is widely known throughout the rest of the world for his fundamental thinking in the field. His birthday is observed every year as the National Librarian Day in India.
The Nippon Decimal Classification is a system of library classification developed for mainly Japanese-language books maintained and revised by the Japan Library Association since 1948. Originally developed in 1929 by Kiyoshi Mori, the 10th and latest edition of this system was published in 2014. The decimal notation system is similar to the Dewey Decimal System, and the order of main classes is inspired from the Cutter Expansive Classification. The system is based upon using a three digit number to classify subjects, where more digits can be added if necessary and a decimal point is used to separate the third and fourth digit. The first division level is called a class, the second level is called a division, and the third level is called a section. Each '1-9' digit is used to represent a specific category, with the digit '0' being used to represent general works.
The following outline is provided as an overview of and topical guide to library and information science:
Dorothy Louise Porter Wesley was a librarian, bibliographer and curator, who built the Moorland-Spingarn Research Center at Howard University into a world-class research collection. She was the first African American to receive a library science degree from Columbia University. Porter published numerous bibliographies on African American history. When she realized that the Dewey Decimal System had only two classification numbers for African Americans, one for slavery and one for colonization, she created a new classification system that ordered books by genre and author.
An academic library is a library that is attached to a higher education institution and serves two complementary purposes: to support the curriculum and the research of the university faculty and students. It is unknown how many academic libraries there are worldwide. An academic and research portal maintained by UNESCO links to 3,785 libraries. According to the National Center for Education Statistics, there are an estimated 3,700 academic libraries in the United States. In the past, the material for class readings, intended to supplement lectures as prescribed by the instructor, has been called reserves. Previously before the electronic appliances became available, the reserves were supplied as actual books or as photocopies of appropriate journal articles. Modern academic libraries generally also provide access to electronic resources.
Age appropriateness refers to people behaving as predicted by their perspective timetable of development. The perspective timetable is embedded throughout people's social life, primarily based on socially-agreed age expectations and age norms. For a given behavior, such as crawling, learning to walk, learning to talk, etc., there are years within which the behavior is regarded appropriate. By contrast, if the behavior falls out of the age range, it will be considered age-inappropriate. Most people are adhered to these age norms and are aware of whether their timing is "early," "delayed," or "on time."
Music librarianship is the area of librarianship that pertains to music collections and their development, cataloging, preservation and maintenance, as well as reference issues connected with musical works and music literature. Music librarians often have degrees in both music and librarianship. Music librarians deal with standard librarianship duties such as cataloging and reference, which become more complicated when music scores and recordings are involved. Therefore, music librarians generally read music and have at least a basic understanding of both music theory and music history to aid in their duties.
Play is a range of intrinsically motivated activities done for recreational pleasure and enjoyment. Play is commonly associated with children and juvenile-level activities, but may be engaged in at any life stage, and among other higher-functioning animals as well, most notably mammals and birds.
Charles Martel was an American librarian responsible for the creation of the Library of Congress Classification; he is often considered to be one of the most influential librarians in American library history.
Metis is a Dewey-free library classification system developed and implemented in 2011 by Sue Giffard, Tali Balas Kaplan, Jennifer Still, and Andrea Dolloff, the librarians at the Ethical Culture School in New York City. The system places the thinking, interests, information needs and information-seeking behavior of children at its center. It was developed as an alternative to the Dewey Decimal Classification System and the practices which customarily accompany that system in school and public libraries in the United States: namely, the alphabetical arrangement of fiction by author, and the frequent arrangement of biographies in alphabetical order by biographee. The Metis system was designed to encourage productive independent browsing by children, as well as allowing for successful catalog searching by elementary school students.
Dewey-free refers to library classification schemes developed as alternatives to Dewey Decimal Classification (DDC). Dewey-free systems are often based on the BISAC subject headings developed by the Book Industry Study Group, and are typically implemented in libraries with smaller collections. Instead of using numerical notation to indicate a document's shelving location, Dewey-free systems organize documents alphabetically by natural language words. Dewey-free systems have been implemented in both public and school libraries.
Indigenous librarianship is a distinct field of librarianship that brings Indigenous approaches to areas such as knowledge organization, collection development, library and information services, language and cultural practices, and education. The Encyclopedia of Library and Information Sciences states that Indigenous librarianship emerged as a "distinct field of practice and an arena for international scholarship in the late twentieth century bolstered by a global recognition of the value and vulnerability of Indigenous knowledge systems, and of the right of Indigenous peoples to control them."
