Recto is the "right" or "front" side and verso is the "left" or "back" side when text is written or printed on a leaf of paper ( folium ) in a bound item such as a codex , book , broadsheet , or pamphlet .
35-404: In double-sided printing , each leaf has two pages – front and back. In modern books, the physical sheets of paper are stacked and folded in half, producing two leaves and four pages for each sheet. For example, the outer sheet in a 16-page book will have one leaf with pages 1 (recto) and 2 (verso), and another leaf with pages 15 (recto) and 16 (verso). Pages 1 and 16, for example, are printed on
70-448: A reversing automatic document feeder (RADF) for scanning both sides. Higher volume printers may effectively have two print engines in a single device, and are able to print both sides of the paper in a single pass. Duplex print devices, depending on options, software, and printer settings, can print single-sided page to single-sided page (1:1) or double-sided page to double-sided page (2:2). Many can also combine single-sided pages into
105-409: A colophon or on the title page became more widespread. There are two types of printed incunabula: the block book , printed from a single carved or sculpted wooden block for each page (the same process as the woodcut in art, called xylographic ); and the typographic book , made by individual cast-metal movable type pieces on a printing press . Many authors reserve the term "incunabula" for
140-455: A manuscript is numbered, and the sides are referred to as folium rēctum and folium versum , abbreviated as r and v respectively. Editions of manuscripts will thus mark the position of text in the original manuscript in the form fol. 1r , sometimes with the r and v in superscript, as in 1 , or with a superscript o indicating the ablative rēctō foliō , versō , as in 1r . This terminology has been standard since
175-402: A book. Short-edge binding allows the pages to be oriented correctly if they are flipped vertically, as in a notepad. This second form of printing/binding is sometimes known as "tumble." If the printing is done in landscape mode, these concepts are transposed since the print direction is different. Single-sided printers can print on both sides of the paper via manual removal and turning over of
210-404: A double-sided page format (1:2). Double-sided booklet formats (2:2 with a center fold) are also available, depending on optional outputs from the printer. Duplexed documents can be printed to be bound on either the short edge or the long edge. This functionality is mostly available on printers that come with a duplexer. Long edge binding in portrait mode allows pages to be turned side-to-side like
245-435: A printed book as an incunable does not reflect changes in the printing process, and many books printed for some years after 1500 are visually indistinguishable from incunables. The term " post-incunable " is now used to refer to books printed after 1500 up to 1520 or 1540, without general agreement. From around this period the dating of any edition becomes easier, as the practice of printing the place and year of publication using
280-679: A single volume of a multi-volume work as a separate item, as well as fragments or copies lacking more than half the total leaves. A complete incunable may consist of a slip, or up to ten volumes. In terms of format , the 30,000-odd editions comprise: 2,000 broadsides , 9,000 folios , 15,000 quartos , 3,000 octavos , 18 12mos, 230 16mos, 20 32mos, and 3 64mos. ISTC at present cites 528 extant copies of books printed by Caxton , which together with 128 fragments makes 656 in total, though many are broadsides or very imperfect (incomplete). Apart from migration to mainly North American and Japanese universities, there has been little movement of incunabula in
315-445: A stack of sheets after one side is printed on; however, the user has to manually turn the (half-done) print job over and re-invoke the printing of the document, with care to ensure that the order and orientation is correct. Printing software frequently has an option to print only odd or even pages, simplifying this process. In commercial printing (books, magazines, newspapers, etc.), the term applied to imparting an image to both sides of
350-639: Is fifteener , meaning "fifteenth-century edition". The term incunabula was first used in the context of printing by the Dutch physician and humanist Hadrianus Junius (Adriaen de Jonghe, 1511–1575), in a passage in his work Batavia (written in 1569; published posthumously in 1588). He referred to a period " inter prima artis [typographicae] incunabula " ("in the first infancy of the typographic art"). The term has sometimes been incorrectly attributed to Bernhard von Mallinckrodt (1591–1664), in his Latin pamphlet De ortu ac progressu artis typographicae ("On
385-487: Is Schedel's Nuremberg Chronicle ("Liber Chronicarum") of 1493, with about 1,250 surviving copies (which is also the most heavily illustrated). Many incunabula are unique, but on average about 18 copies survive of each. This makes the Gutenberg Bible , at 48 or 49 known copies, a relatively common (though extremely valuable) edition. Counting extant incunabula is complicated by the fact that most libraries consider

Incunable is the anglicised form of incunabulum , reconstructed singular of Latin incunabula , which meant " swaddling clothes", or " cradle ", which could metaphorically refer to "the earliest stages or first traces in the development". A former term for incunable
455-489: Is necessary to ensure accurate backing up of the job. Some printers only support duplexing if an optional attachment is fitted. Incunable An incunable or incunabulum ( pl. : incunables or incunabula , respectively) is a book, pamphlet, or broadside that was printed in the earliest stages of printing in Europe, up to the year 1500. Incunabula were produced before the printing press became widespread on
490-470: Is the folia ("leaves") rather than the pages, that are numbered. Thus, each folium carries a consecutive number on its recto side, while on the verso side there is no number. This was also very common in e.g. internal company reports in the 20th century, before double-sided printers became commonplace in offices. Double-sided printing Duplex printing is a feature of some computer printers and multi-function printers (MFPs) that allows
525-462: Is the norm for printed books but was an important advantage of the printing press over the much older Asian woodblock printing method, which printed by rubbing from behind the page being printed, and so could only print on one side of a piece of paper. The distinction between recto and verso can be convenient in the annotation of scholarly books, particularly in bilingual edition translations. The "recto" and "verso" terms can also be employed for
560-506: The Hypnerotomachia Poliphili printed by Aldus Manutius with important illustrations by an unknown artist. Other printers of incunabula were Günther Zainer of Augsburg , Johannes Mentelin and Heinrich Eggestein of Strasbourg , Heinrich Gran of Haguenau , Johann Amerbach of Basel , William Caxton of Bruges and London, and Nicolas Jenson of Venice . The first incunable to have woodcut illustrations
595-620: The UK , the term generally covers 1501–1520, and for books printed in mainland Europe , 1501–1540. The data in this section were derived from the Incunabula Short-Title Catalogue (ISTC). The number of printing towns and cities stands at 282. These are situated in some 18 countries in terms of present-day boundaries. In descending order of the number of editions printed in each, these are: Italy, Germany, France, Netherlands, Switzerland, Spain, Belgium, England, Austria,
630-512: The 17th century. Michel Maittaire (1667–1747) and Georg Wolfgang Panzer (1729–1805) arranged printed material chronologically in annals format, and in the first half of the 19th century, Ludwig Hain published the Repertorium bibliographicum —a checklist of incunabula arranged alphabetically by author: "Hain numbers" are still a reference point. Hain was expanded in subsequent editions, by Walter A. Copinger and Dietrich Reichling , but it

The following table shows the 20 main 15th century printing locations; as with all data in this section, exact figures are given, but should be treated as close estimates (the total editions recorded in ISTC at August 2016 is 30,518): The 18 languages that incunabula are printed in, in descending order, are: Latin, German , Italian , French , Dutch , Spanish , English, Hebrew , Catalan , Czech , Greek , Church Slavonic , Portuguese , Swedish , Breton , Danish , Frisian and Sardinian (see diagram). Only about one edition in ten (i.e. just over 3,000) has any illustrations, woodcuts or metalcuts . The "commonest" incunable
700-454: The beginnings of modern codicology in the 17th century. In 2011, Martyn Lyons argued that the term rēctum "right, correct, proper" for the front side of the leaf derives from the use of papyrus in late antiquity , as a different grain ran across each side, and only one side was suitable to be written on, so that usually papyrus would carry writing only on the "correct", smooth side (and just in exceptional cases would there be writing on
735-538: The continent and are distinct from manuscripts , which are documents written by hand. Some authorities on the history of printing include block books from the same time period as incunabula, whereas others limit the term to works printed using movable type . As of 2021, there are about 30,000 distinct incunable editions known. The probable number of surviving individual copies is much higher, estimated at 125,000 in Germany alone. Through statistical analysis, it

A recto-verso drawing is a sheet with drawings on both sides, for example in a sketchbook —although usually in these cases there is no obvious primary side. Some works are planned to exploit being on two sides of the same piece of paper, but usually the works are not intended to be considered together. Paper was relatively expensive in
805-526: The last five centuries. None were printed in the Southern Hemisphere , and the latter appears to possess less than 2,000 copies, about 97.75% remain north of the equator. However, many incunabula are sold at auction or through the rare book trade every year. The British Library 's Incunabula Short Title Catalogue now records over 29,000 titles, of which around 27,400 are incunabula editions (not all unique works). Studies of incunabula began in
840-812: The latter. The spread of printing to cities both in the North and in Italy ensured that there was great variety in the texts and the styles which appeared. Many early typefaces were modelled on local writing or derived from various European Gothic scripts, but there were also some derived from documentary scripts like Caxton 's, and, particularly in Italy, types modelled on handwritten scripts and calligraphy used by humanists . Printers congregated in urban centres where there were scholars , ecclesiastics , lawyers , and nobles and professionals who formed their major customer base. Standard works in Latin inherited from
875-591: The medieval tradition formed the bulk of the earliest printed works, but as books became cheaper, vernacular works (or translations into vernaculars of standard works) began to appear. Famous incunabula include two from Mainz , the Gutenberg Bible of 1455 and the Peregrinatio in terram sanctam of 1486, printed and illustrated by Erhard Reuwich ; the Nuremberg Chronicle written by Hartmann Schedel and printed by Anton Koberger in 1493; and
910-564: The number of pages. The terms are shortened from Latin: rēctō foliō and versō foliō (which translate as "on the right side of the leaf" and "on the back side of the leaf"). The two opposite pages themselves are called folium rēctum and folium versum in Latin, and the ablative rēctō , versō already imply that the text on the page (and not the physical page itself) are referred to. In codicology , each physical sheet ( folium , abbreviated fol. or f. ) of
945-436: The past; good drawing paper still is much more expensive than normal paper. By book publishing convention, the first page of a book, and sometimes of each section and chapter of a book, is a recto page, and hence all recto pages will have odd numbers and all verso pages will have even numbers. In many early printed books or incunables and still in some 16th-century books (e.g. João de Barros 's Décadas da Ásia ), it
980-439: The printed book evolved fully as a mature artefact with a standard format. After about 1540 books tended to conform to a template that included the author, title-page, date, seller, and place of printing. This makes it much easier to identify any particular edition. As noted above, the end date for identifying a printed book as an incunable is convenient but was chosen arbitrarily; it does not reflect any notable developments in
1015-421: The printing of a sheet of paper on both sides automatically. Print devices without this capability can only print on a single side of paper, sometimes called single-sided printing or simplex printing . Consumer and low-to-medium volume office printers use a duplexing unit that reverses a piece of paper after the first side has been printed. Duplex multifunction printers that also support duplex scanning have
1050-401: The printing process around the year 1500. Books printed for a number of years after 1500 continued to look much like incunables, with the notable exception of the small format books printed in italic type introduced by Aldus Manutius in 1501. The term post-incunable is sometimes used to refer to books printed "after 1500—how long after, the experts have not yet agreed." For books printed in
1085-573: The reverse side of the leaf). The terms "recto" and "verso" are also used in the codicology of manuscripts written in right-to-left scripts , like Syriac , Arabic and Hebrew . However, as these scripts are written in the other direction to the scripts witnessed in European codices, the recto page is to the left while the verso is to the right. The reading order of each folio remains first verso, then recto, regardless of writing direction . The terms are carried over into printing ; recto-verso

It is not found in English before the mid-19th century. Junius set an end-date of 1500 to his era of incunabula , which remains the convention in modern bibliographical scholarship. This convenient but arbitrary end-date for identifying
1155-586: The same side of the physical sheet of paper, combining recto and verso sides of different leaves. The number of pages in a book using this binding technique must thus be a multiple of four, and the number of leaves must be a multiple of two, but unused pages are typically left unnumbered and uncounted. A sheet folded in this manner is known as a folio , a word also used for a book or pamphlet made with this technique. Looseleaf paper consists of unbound leaves. Sometimes single-sided or blank leaves are used for numbering or counting and abbreviated "l." instead of "p." for
1190-408: The substrate at the same time is 'perfecting' and is commonly achieved—especially in lithography —by passing the substrate through a perfecting drum, thus turning the sheet over after the first side is printed. The turned sheet then continues its way through the press, being gripped at the opposite edge whilst the second side is printed. This in effect tumbles the job; therefore, accurate sheet sizing
