by the typewriter, pasted upon cardboard, and then cut apart to slip 



into the indexer. 



All that can be done by the l)ookbinder, like the mounting of cards, 

 the preparation of the lludolph indexer books and the covers for the 

 pamphlets, the pasting and cutting of strips for the indexer, repairs, 

 etc., is done in the bindery of the library. All books are stitched 

 with from four to seven threads which are often of silk, the backs are 

 covered with binder's gauze and provided with linen guards stitched 

 on. All plates are attached to muslin guards, uuich-used volumes 

 have parchment corners, and all are gilded on the upper edge. All 

 parts of yet incomplete volumes of journals, and works issued in parts, 

 are temporarily bound in Rudolph binders. The cover of one of these 

 binders costs the library 30 cents, and the appliances for holding each 

 pamphlet, 10 cents, so the cost of a volume of five pamphlets would be 

 80 cents, certainly a relatively heavy expense, but such a volume is 

 extremely solid and very elegant. If a pamphlet is to be bound by 

 itself, the simple Newberry binder is used, which costs the library 

 4i cents. The production of the Rudolph indexer books costs the 

 library, for the size 12i by 10 inches, with 10 stiff leaves, or 19 by 10 

 inches with 15 flexible leaves, $2.20 each. 



sides of the same leaf. A further very remarkable manifolding process in blue- 

 print is used by Mr. Rudolph for the formation of catalogues. For instance, the 

 Newberry Library in 1899 prepared 10 copies of a folio volume of 500 pages, which 

 bears the title: "British Museum. Catalogue of Printed Books. Accessions, Janu- 

 uary, 1880, to March, 1899. Academies, with an Index." It ig an alphaljetically 

 arranged register, comprising some 5,000 titles (with an index of about 3,000 entries) 

 of accessions concerning "Academies" acquired by the British Museum from 1880 

 to 1899; these titles were contained in 446 single publications of the British Museum, 

 so that it was difficult to find anything in them. They were cut apart, arranged in 

 al])habetical order, and manifolded by blueprinting, which is very quickly done and 

 very cheap. A page of 25 titles costs 4 cents exclusive of labor, a volume of 500 

 pages therefore costs $20 a copy. It w^as contemplated to combine in 40 such vol- 

 umes, alphal)etically arranged, the 900,000 titles of new accessions to the British 

 Museum from 1880 to 1899, but this was stopped after the first volume, because the 

 British Museum had, in the meantime, the prospect of a more speedy publication of 

 its supplementary catalogue of printed books. The method employed by the New- 

 berry Library is, however, so remarkable and promising that I did not wish to leave 

 it unmentioned. Mr. Rudolph had the great kindness to jaresent me with a copy of the 

 10 that had been produced, as well as to provide me with examples of the various 

 stages of the work, wdiich I will be glad to show to any who are interested. On the 

 method itself he has published an article in the Li hrari/ Journal, XXIV, 1899, ]ip. 

 102-105, "The Bluei)rint Process fur Printing Catalogues." I will further say that the 

 leaves of the catalogue I have mentioned have blueprinting on both sides, hut which 

 is only apparently effected by pasting together, back to back, two very thin leaves 

 printed only on one side. Blueprinting can only bedone on oneside, and the originals, 

 too, must not bear print upon the back. Since this is the case with 200 of the first 

 leaves of the British Museum Catalogue just referred to, which later has been pub- 

 lished, printed on only (me side, it has been necessary, before their reproducti()n by 

 blueprint, to S[)lit them apart, whicli for this purpose has also been accomplished. 

 Mr. Rudolph's ingenuity has been successful in overcoming all difficulties.
