At the present time there are many binders working in England who are capable of turning out work of the highest class, and fortunately there are book-lovers here and in America with the taste and means to commission such work. Probably, if a man were bold enough to spend five or ten thousand pounds on binding the finest books that are being produced at the present time, he would find, if the money were wisely spent, that he had got a library that would be celebrated all over the world. There is an interesting revival in the use of arms-blocks on bindings, and when certain modern libraries come to be dispersed their owners will be remembered by their books in the same way as are the original owners of the many armorial bindings that have come down to us from the past.
There are some qualities that are common to all well-bound books. Of course abnormal books have to be treated specially, but it may generally be said that every leaf of a book should open right to the back. This means that all single leaves and plates should be attached by guards, and that no overcasting or pasting-in should be allowed, and it also means that the back should be truly flexible. The sections should be sewn to flexible cords or tapes, the ends of these should be firmly attached to the boards, and the back should be covered with some flexible material, such as leather, which, while protecting the sewing-thread or cord, shall itself add to the strength of the binding. A fine binding will have many other features added by way of refinement or elaboration, but unless it has these qualities it is likely to be an unsatisfactory piece of work. A well-bound book should open well and stay open, and shut well and stay shut. The binder can bind any book so that it will not open, but there are some books that he cannot bind so that they will open and shut "sweetly."
Bookbinding is only one part of the larger craft of book production, and to obtain a perfect book it is necessary that the workers in each branch of the craft should have a common ideal of what a book should be, and that each should do his part in such a way that this ideal may be attained. Unfortunately it too often happens that the printers are quite content if their printing looks perfect as it comes from the press, with the result--through errors in the choice of paper or the number of leaves to a section--that the bookbinder has unnecessary and sometimes unsurmountable obstacles put in his way. A book that will not open freely and that gapes like a dead oyster when it ought to be shut is not pleasant to use, and when these faults are noticed the binder generally gets the blame. Sometimes he deserves the blame, for the fault may be his, but more often than not the fault lies with the paper. To open a book a certain number of leaves of paper must be bent, and if the paper is so stiff that a single leaf will not fall over by its own weight, the book cannot be made to open quite satisfactorily if bound in the ordinary way. By swinging each leaf on a guard it is possible to bind a pack of playing-cards into something like a book which will open and shut freely, but that this _can_ be done is no excuse for the production of books which necessitate this drastic treatment before they can be bound satisfactorily.
