In general usage, a thesaurus is a reference work that lists words grouped together according to similarity of meaning (containing synonyms and sometimes antonyms), in contrast to a dictionary, which provides definitions for words, and generally lists them in alphabetical order.

The main purpose of such reference works is to help the user "to find the word, or words, by which [an] idea may be most fitly and aptly expressed" – to quote Peter Mark Roget, architect of the best known thesaurus in the English language.

A dictionary is a collection of words in one or more specific languages, often arranged alphabetically (or by radical and stroke for ideographic languages), which may include information on definitions, usage, etymologies, phonetics, pronunciations, translation, etc.

or a book of words in one language with their equivalents in another, sometimes known as a lexicon.

It is a lexicographical product which shows inter-relationships among the data.

An encyclopedia or encyclopaedia (also spelled encyclopædia, see spelling differences) is a type of reference work or compendium holding a comprehensive summary of information from either all branches of knowledge or a particular branch of knowledge.

Reference is a relation between objects in which one object designates, or acts as a means by which to connect to or link to, another object.

The first object in this relation is said to refer to the second object.

The second object, the one to which the first object refers, is called the referent of the first object.

A library is a collection of sources of information and similar resources, made accessible to a defined community for reference or borrowing.

It provides physical or digital access to material, and may be a physical building or room, or a virtual space, or both.

A library's collection can include books, periodicals, newspapers, manuscripts, films, maps, prints, documents, microform, CDs, cassettes, videotapes, DVDs, Blu-ray Discs, e-books, audiobooks, databases, and other formats.

Libraries range in size from a few shelves of books to several million items.

In Latin and Greek, the idea of a bookcase is represented by Bibliotheca and Bibliothēkē (Greek: βιβλιοθήκη): derivatives of these mean library in many modern languages, e.g. French bibliothèque.
