Bibliography (from Greek βιβλίον biblion, "book" and -γραφία -graphia, "writing"), as a discipline, is traditionally the academic study of books as physical, cultural objects; in this sense, it is also known as bibliology (from Greek -λογία, -logia). Carter and Barker (2010) describe bibliography as a twofold scholarly discipline—the organized listing of books (enumerative bibliography) and the systematic description of books as physical objects (descriptive bibliography).
The word bibliographia (βιβλιογραφία) was used by Greek writers in the first three centuries AD to mean the copying of books by hand. In the 12th century, the word started being used for "the intellectual activity of composing books". The 17th century then saw the emergence of the modern meaning, that of description of books. Currently, the field of bibliography has expanded to include studies that consider the book as a material object. Bibliography in its systematic pursuit of understanding the past and the present through written and printed documents describes a way and means of extracting information from this material. Bibliographers are interested in comparing versions of texts to each other rather than in interpreting their meaning or assessing their significance. 
Bibliography as a field of study
Bibliography is a specialized aspect of library science (or library and information science, LIS) and documentation science. The founder of documentation, Paul Otlet, wrote about "the science of bibliography". However, there have recently been voices claiming that "the bibliographical paradigm" is obsolete, and it is not today common in LIS. A defense of the bibliographical paradigm was provided by Hjørland (2007). The quantitative study of bibliographies is known as bibliometrics, which is today an influential subfield in LIS. 
Branches of bibliography
Carter and Barker (2010) describe bibliography as a twofold scholarly discipline—the organized listing of books (enumerative bibliography) and the systematic description of books as physical objects (descriptive bibliography). These two distinct concepts and practices have separate rationales and serve differing purposes. Innovators and originators in the field include W. W. Greg, Fredson Bowers, Philip Gaskell, G. Thomas Tanselle.
Bowers (1949) refers to enumerative bibliography as a procedure that identifies books in “specific collections or libraries,” in a specific discipline, by an author, printer, or period of production (3). He refers to descriptive bibliography as the systematic description of a book as a material or physical artifact. Analytical bibliography, the cornerstone of descriptive bibliography, investigates the printing and all physical features of a book that yield evidence establishing a book's history and transmission (Feather 10). It is the preliminary phase of bibliographic description and provides the vocabulary, principles and techniques of analysis that descriptive bibliographers apply and on which they base their descriptive practice.
Descriptive bibliographers follow specific conventions and associated classification in their description. Titles and title pages are transcribed in a quasi-facsimile style and representation. Illustration, typeface, binding, paper, and all physical elements related to identifying a book follow formulaic conventions, as Bower's established in his foundational opus, The Principles of Bibliographic Description. The thought expressed in this book expands substantively on W. W. Greg's groundbreaking theory that argued for the adoption of formal bibliographic principles (Greg 29). Fundamentally, analytical bibliography is concerned with objective, physical analysis and history of a book while descriptive bibliography employs all data that analytical bibliography furnishes and then codifies it with a view to identifying the ideal copy or form of a book that most nearly represents the printer’s initial conception and intention in printing.
In addition to viewing bibliographic study as being composed of four interdependent approaches (enumerative, descriptive, analytical, and textual), Bowers notes two further subcategories of research, namely historical bibliography and aesthetic bibliography. Both historical bibliography, which involves the investigation of printing practices, tools, and related documents, and aesthetic bibliography, which examines the art of designing type and books, are often employed by analytical bibliographers.
D. F. McKenzie extended previous notions of bibliography as set forth by W. W. Greg, Bowers, Gaskell and Tanselle. He describes the nature of bibliography as "the discipline that studies texts as recorded forms, and the processes of their transmission, including their production and reception" (1999 12). This concept broadens the scope of bibliography to include "non-book texts" and an accounting for their material form and structure, as well as textual variations, technical and production processes that bring sociocultural context and effects into play. McKenzie's perspective contextualizes textual objects or artifacts with sociological and technical factors that have an effect on production, transmission and, ultimately, ideal copy (2002 14). Bibliography, generally, concerns the material conditions of books [as well as other texts] how they are designed, edited, printed, circulated, reprinted, collected.
Bibliographic works differ in the amount of detail depending on the purpose and can generally be divided into two categories: enumerative bibliography (also called compilative, reference or systematic), which results in an overview of publications in a particular category and analytical or critical bibliography, which studies the production of books. In earlier times, bibliography mostly focused on books. Now, both categories of bibliography cover works in other media including audio recordings, motion pictures and videos, graphic objects, databases, CD-ROMs and websites.
An enumerative bibliography is a systematic list of books and other works such as journalarticles. Bibliographies range from "works cited" lists at the end of books and articles, to complete and independent publications. A notable example of a complete, independent publication is Gow's, A. E. Housman: A Sketch, Together with a List of His Classical Papers (1936). As separate works, they may be in bound volumes such as those shown on the right, or computerized bibliographic databases. A library catalog, while not referred to as a "bibliography," is bibliographic in nature. Bibliographical works are almost always considered to be tertiary sources.
Enumerative bibliographies are based on a unifying principle such as creator, subject, date, topic or other characteristic. An entry in an enumerative bibliography provides the core elements of a text resource including a title, the creator(s), publication date and place of publication. Belanger (1977) distinguishes an enumerative bibliography from other bibliographic forms such as descriptive bibliography, analytical bibliography or textual bibliography in that its function is to record and list, rather than describe a source in detail or with any reference to the source's physical nature, materiality or textual transmission. The enumerative list may be comprehensive or selective. One noted example would be Tanselle's bibliography that exhaustively enumerates topics and sources related to all forms of bibliography. A more common and particular instance of an enumerative bibliography relates to specific sources used or considered in preparing a scholarly paper or academic term paper.
Citation styles vary.
An entry for a book in a bibliography usually contains the following elements:
- place of publication
- publisher or printer
- date of publication
An entry for a journal or periodical article usually contains:
- article title
- journal title
- date of publication
A bibliography may be arranged by author, topic, or some other scheme. Annotated bibliographies give descriptions about how each source is useful to an author in constructing a paper or argument. These descriptions, usually a few sentences long, provide a summary of the source and describe its relevance. Reference management software may be used to keep track of references and generate bibliographies as required.
Bibliographies differ from library catalogs by including only relevant items rather than all items present in a particular library. However, the catalogs of some national libraries effectively serve as national bibliographies (de), as the national libraries own almost all their countries' publications.
Fredson Bowers described and formulated a standardized practice of descriptive bibliography in his Principles of Bibliographical Description (1949). Scholars to this day treat Bowers' scholarly guide as authoritative. In this classic text, Bowers describes the basic function of bibliography as, "[providing] sufficient data so that a reader may identify the book described, understand the printing, and recognize the precise contents" (124).
Descriptive bibliographies as scholarly product
Descriptive bibliographies as a scholarly product usually include information on the following aspect of a given book as a material object:
- Format and Collation/Pagination Statement – a conventional, symbolic formula that describes the book block in terms of sheets, folds, quires, signatures, and pages
- According to Bowers (193), the format of a book is usually abbreviated in the collation formula:
- Broadsheet: I° or b.s. or bs.
- Folio: 2° or fol.
- Quarto: 4° or 4to or Q° or Q
- Octavo: 8° or 8vo
- Duodecimo: 12° or 12mo
- Sexto-decimo: 16° or 16mo
- Tricesimo-secundo: 32° or 32mo
- Sexagesimo-quarto: 64° or 64mo
- The collation, which follows the format, is the statement of the order and size of the gatherings.
- For example, a quarto that consists of the signed gatherings:
- 2 leaves signed A, 4 leaves signed B, 4 leaves signed C, and 2 leaves signed D
- would be represented in the collation formula:
- 4°: A2B-C4D2
- For example, a quarto that consists of the signed gatherings:
- According to Bowers (193), the format of a book is usually abbreviated in the collation formula:
- Binding – a description of the binding techniques (generally for books printed after 1800)
- Title Page Transcription – a transcription of the title page, including rule lines and ornaments
- Contents – a listing of the contents (by section) in the book
- Paper – a description of the physical properties of the paper, including production process, an account of chain-line measurements, and a description of watermarks (if present)
- Illustrations – a description of the illustrations found in the book, including printing process (e.g. woodblock, intaglio, etc.), measurements, and locations in the text
- Presswork – miscellaneous details gleaned from the text about its production
- Copies Examined – an enumeration of the copies examined, including those copies' location (i.e. belonging to which library or collector)
This branch of the bibliographic discipline examines the material features of a textual artifact – such as type, ink, paper, imposition, format, impressions and states of a book – to essentially recreate the conditions of its production. Analytical bibliography often uses collateral evidence – such as general printing practices, trends in format, responses and non-responses to design, etc. – to scrutinize the historical conventions and influences underlying the physical appearance of a text. The bibliographer utilizes knowledge gained from the investigation of physical evidence in the form of a descriptive bibliography or textual bibliography. Descriptive bibliography is the close examination and cataloging of a text as a physical object, recording its size, format, binding, and so on, while textual bibliography (or textual criticism) identifies variations – and the aetiology of variations – in a text with a view to determining "the establishment of the most correct form of [a] text (Bowers 498).
A bibliographer is a person who describes and lists books and other publications, with particular attention to such characteristics as authorship, publication date, edition, typography, etc. A person who limits such efforts to a specific field or discipline is a subject bibliographer."
A bibliographer, in the technical meaning of the word, is anyone who writes about books. But the accepted meaning since at least the 18th century is a person who attempts a comprehensive account—sometimes just a list, sometimes a fuller reckoning—of the books written on a particular subject. In the present, bibliography is no longer a career, generally speaking; bibliographies tend to be written on highly specific subjects and by specialists in the field.
The term bibliographer is sometimes—in particular subject bibliographer—today used about certain roles performed in libraries and bibliographic databases.
Systematic lists of media other than books can be referred to with terms formed analogously to bibliography:
Arachniography is a term coined by NASA research historian Andrew J. Butrica, which means a reference list of URLs about a particular subject. It is equivalent to a bibliography in a book. The name derives from arachne in reference to a spider and its web.

Knowing the proper term for your paper’s list of citations can be confusing. Do I call it a works cited page? Should it actually be called a bibliography? How is it different from a reference list? In this article, we explain what these three terms mean and how they are different or related to one another.
To begin, each citation style has its own way of naming the list of sources you used in your paper. Here we break down the differences in these list types, so that you can better understand which option works best for your work.
A “Works Cited” list is an alphabetical list of works cited, or sources you specifically called out while composing your paper. All works that you have quoted or paraphrased should be included. Works Cited is generally used when citing sources using MLA format (Modern Language Association) style, and sources should be listed in alphabetical order by author’s last name.
Example Works Cited entry:
Middlekauff, Robert. The Glorious Cause: The American Revolution. Oxford UP, 2007.
References or “Reference List”
A “Reference List” is very similar to a Works Cited list, and is a term used when citing sources using APA format (American Psychological Association) style. The page should be titled “References,” and is arranged alphabetically by author last name.
Example References entry:
Middlekauff, R. (2007). The glorious cause: The American Revolution. Oxford, UK: Oxford University Press.
Bibliographies, on the other hand, differ greatly from Works Cited and References lists. In Works Cited and References, you only list items you have actually referred to and cited in your paper. A Bibliography, meanwhile, lists all the material you have consulted in preparing your essay, whether you have actually referred to and cited the work or not. This includes all sources that you have used in order to do any research. Bibliographies are often used in Chicago and Turabian citation styles. They usually contain a long reference that has a corresponding footnote within the body of the paper.
Example Bibliography entry:
Middlekauff, Robert. The Glorious Cause: The American Revolution. Oxford, UK: Oxford University Press, 2007.
