miniature book

norm: miniature book

text:
A small to very small book, generally up to 3, or perhaps even 4 inches in height, in which the principal, if not only, interest lies in its small size. It is designed on a small scale (although some consider books reduced in size by photographic means to qualify as miniatures), printed with small type, bound and decorated on a small scale, and, if illustrated, provided with reproductions appropriate to the size of the book.

The idea of a miniature is artificial, although they are very popular. Many Bibles, devotional works, almanacs, classics, etc., have been issued in miniature form from an early date.

morocco

norm: morocco

text:
A vegetable tanned leather having a characteristic pinhead grain pattern developed either naturally or by means of graining or boarding, but never by embossing. The most common and characteristic grain pattern is known as "hard grain."

By long usage, the term "morocco" is taken to denote a goatskin, tanned by any vegetable tannage, and boarded in the wet condition; in a more strict interpretation, however, morocco is defined as a goatskin tanned exclusively with SUMAC, and boarded in the wet condition. Leather made from vegetable tanned goatskin having a grain pattern resembling that of genuine morocco, but produced other than by hand boarding, is more properly termed "morocco grained goat" or "assisted morocco. "

When properly produced, morocco goatskins are very durable, flexible, beautifully grained, and relatively strong, making them eminently suitable for use as a bookbinding leather. The skins are (or, at least, have been) obtained from several areas, including: wild goats, principally from Africa, which generally produce heavy skins with a very bold grain, e.g., LEVANT; domestic goats, which produce a leather with the more familiar hard grain or PINHEAD MOROCCO; and true PERSIAN MOROCCO, which is produced from Indian or East Indian goatskins. The term, however, is also applied (incorrectly) to East Indian sheepskin tanned with condensed tannins and dressed in imitation of goatskin; so-called Cape morocco (produced from goatskins from the Cape of Good Hope), which, when obtainable, were of high quality and had the most pronounced grain pattern and the richest finish; and NIGER goatskins, which are soft and can be obtained in a wide range of colors.

Alum-tawed "morocco" stained pink, was first produced by the Moors, possibly before the 11th century. Vegetable-tanned morocco was in use in some part of Europe in the 16th century, particularly in Italy where the goat was more common than in the north of Europe, where calfskin was more abundant. Morocco leather was rarely used in England before 1600.

Straight-grained morocco was popular in the late 18th and early 19th centuries. Bright red and green were the most popular colors, with dark blue, black, citron, and even purple skins also being used.

Throughout the 19th century, morocco, in its various grain patterns, was used in the finest bookbinding, and it is still used for much of the better binding, although it is very expensive and is also becoming more and more difficult to obtain.

Today, to refer to a leather as "morocco" gives no indication as to the subspecies "Levant," "Niger," etc., since most of the morocco now used in bookbinding comes from other parts of the world. The only common denominator among the numerous varieties of leather which now go under the name morocco is that they are all goatskins.

morocco

text: A fine kind of grained leather prepared from goatskin.


morocco

text: Leather made from goatskins, tanned with sumac, originally made in the Barbary states, but afterwards very largely in the Levant, and now produced in Europe and America from skins imported from Asia and Africa. The peculiar qualities of true morocco are great firmness of texture, with flexibility, and a grained surface, of which there are many varieties. This surface is produced by a process which consists largely in rolling and folding, called graining. True morocco is of extreme hardness, and makes the most durable book bindings; it is used also for upholstering seats and for similar purposes, and to a certain extent in shoemaking.

Its main disadvantage, other than its highly disagreeable odor, is the tendency of the treated paper to revert to an acid condition in the presence of high relative humidity.


Morris, William

text: An English poet, painter, architect and printer, who led the movement in search of higher standards of workmanship among craft bookbinders in the latter years of the 19th century. It was Morris' wife who recommended that Cobden-Sanderson take up bookbinding. Later Cobden-Sanderson founded the Doves Bindery to bind books produced by the Kelmscott Press. Morris and his group also sought to improve the quality of the materials used in bookbinding, and, under his influence, great emphasis was placed on both utility and beauty. While Morris' name is best remembered for his revival of fine printing, some outstanding bindings were executed on editions of beautifully printed books produced at his Kelmscott Press, which he founded in 1891. These vellum bindings were not ornamented except for the title in gold on the spine, and had projecting covers which were bent over the fore edge. Ribbon ties held the covers closed. They had flat spines, and were sewn on tapes, which were extended to the fore edge to form the ties.

text: Bookbindings decorated by inlaying or onlaying small pieces of leather of various colors to form patterns. The technique is particularly associated with the work of the 19th century French bookbinders, Antoine Michel Padeloup, Louis Fran,cois, and Jean Le Monier. This form of decoration has been used for a considerable length of time; examples of mosaics of inlaid leather, while extremely rare, date back to the 16th century. Painted mosaics consist of geometrical interlacings filled with a colored and varnished incrustation, with borders of gold lines. Very brilliant when first executed, the composition in time cracks and peels off, thus damaging the line work of gold encircling it. See PLATE VII.

The uneven dyeing of paper pulp fibers resulting from the coloring of a small number of fibers before complete dispersion of the dye. This is due to the manner of addition of a hot concentrated solution of dyestuff to the beater, or of dyeing a combination furnish containing fibers which take up the dye more readily than others. 4. An uneven dyeing of a paper due to the application of drops of dye on the web while it is on the Fourdrinier wire or on the finished sheet after it has left the papermaking machine.

In the most typical of such bindings the main decorative feature consists of a blind geometrical pattern with double outline interlacings (strapwork), with either all or part of the background being filled in with dots, small tools, and the like. Various types of small oblong or square stamps were also used, not all mudéjar in character. In typical Muslim tradition, however, tools representing living creatures were avoided. Although the characteristic mudéjar binding was decorated in blind, later bindings were decorated in both blind and gold. Most of the mudéjar bindings have wooden boards (and the remainder pasteboards) and the majority are covered in CORDOVAN LEATHER.

The name derives from the Mudéjares, or Moors, who remained in Spain during and after the Christian reconquest of that country. See also: GÓTICO-MUDÉJAR STYLE.

MUSIC

norm: music

text:
It is not necessary in this work to define what music is, nor enter at all into any disquisition on the subject, as the object is the printing of it only; and all that I shall attempt is to give the plan of a pair of Music Cases, with the characters, and a specimen.

The English musical types have never to my knowledge undergone any improvement, till within a few years, when Mr. Hughes cut two new founts, which are looked upon as the best we have, and the largest of which I have used for this article.

Mr. E. Cowper devised a plan for printing music, in which one page was the lines only, and the other page was the notes, &c. only, and the chase was prepared to turn upon a centre fixed in the table of a press: thus the first impression was that of the lines without the notes, &c. on one page, and the notes, &c. without the lines on the other; the form was then turned half round, and the second impression was, the lines on the notes on one page, and the notes on the lines on the other. There is an objection to this plan for good work, which is, that the page of notes requires a different making ready to the page of lines, and when the two are completed they will be unequal in the effect, for either the lines will be too strong, or the notes have too little impression.

Mr. R. Branston struck out a different mode: he produced his music by the usual process for printing it with the rolling press, only the punches were struck deeper in the plate, and he then took a stereotype plate from it in type metal, and after the white parts were blocked out the music was sufficiently in relief to be printed at the type press. Both these plans were adopted to preserve the continuity of the lines, which in types got rounded off by wear where they joined, and spoiled the appearance.

In distributing music, the compositor should be careful not to injure the corners of the lines.

Music of the Presses. When a house has sufficient business to employ all the presses within it, and a master printer walks through his press room when they are all at work, and hears the creaking of the heads, the thumping of the balls, the noise of the running in and out of the carriage, and all the other miscellaneous, and, to unaccustomed ears, discordant noises, he styles them the music of the presses, which he declares to be the finest music in the world, as it brings grist to his mill.

The Music of the Presses, before the introduction of cylindrical machines worked by steam engines, was a standing toast after dinner at all parties among printers; and I hope it will never be neglected.

NAMES, Ancient, of Cities and Towns.

The names distinguished by an asterisk * and an obelisk † were taken from Dr. Adam Clarke’s Bibliographical Miscellany, where they form two lists. The additional names were collected by myself.

In the towns marked * printing was carried on in the fifteenth century; and Dr. A. Clarke says—“In this List, great care has been taken not to omit one place where printing was carried on prior to the year 1500.”—“In this list, because the name refers to the work executed there, the genitive case has been retained. Panzer in his list has followed the same plan. This will be of some use to the mere English scholar, as he will at once see the same form of the word in its alphabetical order in this list, which he finds in the title of his book.”

In the towns marked † printing has been established and carried on since the fifteenth century, and Dr. A. Clarke observes—“This part might have been much enlarged, but it was not judged indispensably necessary. As the most difficult names are here explained, which usually occur in the titles of books, the residue it is hoped will occasion little embarrassment to any scholar.”—“It may be necessary to observe, for the information of the less experienced reader, that in this Supplement, as the Latin name stands in reference to no printed work, the nominative case has been always used.”

music manuscript

norm: music manuscript

variant: music paper

text: A paper printed with staff lines and used for the writing of musical scores. It is produced from rag and/or bleached chemical wood pulps. It is stiff enough to stand in a music rack and has a surface that will take pencil or pen and ink. Basis weights generally from 60 to 80 pounds (25 X 38—500) or 24 to 30 pounds (17 X 22—500). Erasability is an important characteristic. Music printings are used for reproducing music, and are produced mainly from bleached chemical wood pulp. The paper is well formed and is sized and processed to insure good pick strength and minimum curl. The basis weights range from 60 to 90 pounds (25 X 38—500).

myrabolans

norm: myrabolans

variant: myrobalans

text:
A vegetable tanning material obtained from the dried astringent fruits of certain species of Terminalia, and used extensively in the tanning of leather. The dried fruit is rich in tannin, averaging 30 to 32%, but the percentage varies greatly with different grades and sources.

One of the principal advantages of myrabolan extract, which has to a large extent replaced sumac and plant galls in European tanneries, is its acid-forming properties. It contains 3 to 5% sugars, which is much more than most other tannins contain; consequently fermentation takes place readily in the tan liquor and satisfactory plumping of the hides and skins is obtained in the early stages of tanning. Myrabolan tannin also contains a large proportion of ellagitannic acid, and thus readily deposits bloom. The disadvantages of the tannin are its slow penetration, and its tendency to produce a spongy leather of poor wearing quality. Because of these characteristics, myrabolans is usually blended with other more astringent tannins, e.g., wattle, quebracho, or mangrove, which penetrate faster.

Myrabolans is a pyrogallol class of tannin, with low viscosity, a medium pH (3.2) and salts content, and very high acids content. The tannin also contains chebulinic acid and a fairly high proportion of ellagitannin.

In addition to its used in the tanning industry, myrabolan tannin is also used as a black dye and in the manufacture of some inks. See also: VEGETABLE TANNINS.

nailing

norm: nailing

text: A method of securing the leaves or sections of a book (usually a newspaper or a book in sheets that has an ample binding margin) in which ordinary flat-heated nails, or specially designed nails or staples, are driven through the paper near the binding edge from both sides. The nails are slightly shorter than the thickness of the pile of leaves, so that they do not emerge from the paper on the reverse side of the pile. This style of binding is cut flush and is not rounded and backed. Unless the book is very large, and is made up of suitable paper, a nailed binding usually has poor to very poor OPENABILITY.

natural dyestuffs

norm: natural dyestuffs

text:
A class of dyes extracted and processed from plant or animal sources, as distinguished from dyestuffs manufactured from derivatives of coal-tar. The use of natural dyes predates recorded history. Other dyestuffs were later developed in ancient Greece, Rome, and the Orient, while still others were used in medieval and Renaissance times. Although still used to a limited extent for specialized work or for reasons of economy, their use in archival work is now virtually obsolete.

Few, if any, of the natural dyestuffs are resistant to external influences, such as light; they do, however, fade at different rates. Upon fading, they either darken or undergo a change in hue.

Some of the natural dyestuffs are: blues—indigo, woad, chemic, and Prussian blue; reds—madder, cochineal, brazilwood, alkanet, annatto, and safflower; yellows—fustic, quercitron, dock, goldenrod, sassafras, and tumeric; browns—butternut, catechu, alder, and hemlock; purples—orchil and cudbear; blacks—logwood; and neutral colors—barks of various trees, including birches and oaks, galls and sumac.
