The following outline is provided as an overview of and topical guide to library and information science: Library and information science (LIS) is the scientific study of issues related to libraries and the information fields. This includes academic studies regarding how library resources are used and how people interact with library systems.
Library science (previously termed library studies and library economy) [note 1] is an interdisciplinary or multidisciplinary field that applies the practices, perspectives, and tools of management, information technology, education, and other areas to libraries; the collection, organization, preservation, and dissemination of information resources; and the political economy of information.

In general, a judgment may be any inductively definable assertion in the metatheory. Judgments are used in formalizing deduction systems: a logical axiom expresses a judgment, premises of a rule of inference are formed as a sequence of judgments, and their conclusion is a judgment as well (thus, hypotheses and conclusions of proofs are judgments).
The Handbook of Mathematical Logic [1] in 1977 makes a rough division of contemporary mathematical logic into four areas: . set theory; model theory; recursion theory, and; proof theory and constructive mathematics (considered as parts of a single area).
Mathematics and Plausible Reasoning is a two-volume book by the mathematician George Pólya describing various methods for being a good guesser of new mathematical results. [ 1 ] [ 2 ] In the Preface to Volume 1 of the book Pólya exhorts all interested students of mathematics thus: "Certainly, let us learn proving, but also let us learn guessing."
The five laws of library science is a theory that S. R. Ranganathan proposed in 1931, detailing the principles of operating a library system. Many librarians from around the world accept the laws as the foundations of their philosophy. [1] [2] These laws, as presented in Ranganathan's The Five Laws of Library Science, are: Books are for use.
Computational logic is the branch of logic and computer science that studies how to implement mathematical reasoning and logical formalisms using computers. This includes, for example, automatic theorem provers , which employ rules of inference to construct a proof step by step from a set of premises to the intended conclusion without human ...
