With the emergence of the internet and software
tools such as Calibre and “[let’s share books],”20 librarianship has been given an opportunity, similar to astronomy and the project SETI@home21, to
include thousands of amateur librarians who will,
together with the experts, build a distributed peerto-peer network to care for the catalog of available
knowledge, because
a public library is:
— free access to books for every member of society
— library catalog
— librarian
With books ready to be shared, meticulously
cataloged, everyone is a librarian.
When everyone is librarian, library is
everywhere.22

Transformations
in the Bibliographical Apparatus
of the Sciences [1]
Repertory — Classification — Office
of Documentation
1. Because of its length, its extension to all countries,
the profound harm that it has created in everyone’s
life, the War has had, and will continue to have, repercussions for scientific productivity. The hour for
the revision of the old order is about to strike. Forced
by the need for economies of men and money, and
by the necessity of greater productivity in order to
hold out against all the competition, we are going to
have to introduce reforms into each of the branches
of the organisation of science: scientific research, the
preservation of its results, and their wide diffusion.
Everything happens simultaneously and the distinctions that we will introduce here are only to
facilitate our thinking. Always adjacent areas, or
even those that are very distant, exert an influence
on each other. This is why we should recognize the
impetus, growing each day eve

before our very eyes. The increasing production of
books and periodicals has revealed the inadequacy of
older methods. The increasing internationalisation
of science has required workers to extend the range
of their bibliographic investigations. As a result, a
movement has occurred in all countries, especially
Germany, the United States and England, for the
expansion and improvement of libraries and for
an increase in their numbers. Publishers have been
searching for new, more flexible, better-illustrated,
and cheaper forms of publication that are better-coordinated with each other. Cataloguing enterprises
on a vast scale have been carried out, such as the
International Catalogue of Scientific Literature and
the Universal Bibliographic Repertory. [2]
Three facts, three ideas, especially merit study
for they represent something really new which in
the future can give us direction in this area. They
are: The Repertory, Classification and the Office of
Documentation.

2. The Repertory, like the book, has gradually been
increasing in size, and improvements in it suggest
the emergence of something new which will radically modify our traditional ideas.
From the point of view of form, a book can be
defined as a group of pages cut to the same format
and gathered together in such a way as to form a
whole. It was not always so. For a long time the
Book was a roll, a volumen. The substances which
then took the place of paper — papyrus and parchment — were written on continuously from beginning to end. Reading required unrolling. This was
certainly not very practical for the consultation of
particular passages or for writing on the verso. The
codex, which was introduced in the first centuries of
the modern era and which is the basis of our present
book, removed these inconveniences. But its faults
are numerous. It constitutes something completed,
finished, not susceptible of addition. The Periodical
with its successive issues has given science a contin

tions was
clear. Nor was there any doubt as to the unitary or
monographic notion: one work, one title; one title,
one card. As a result, registers which listed the same
collections of books for each library but which had
constantly to be re-done as the collections expanded,
have gradually been discarded. This was practical
and justified by experience. But upon reflection one
wonders whether the new techniques might not be
more generally applied.
What is a book, in fact, if not a single continuous line which has initially been cut to the length
of a page and then cut again to the size of a justified
line? Now, this cutting up, this division, is purely
mechanical; it does not correspond to any division
of ideas. The Repertory provides a practical means
of physically dividing the book according to the
intellectual division of ideas.
Thus, the manuscript library catalogue on cards
has been quickly followed by catalogues printed on
cards (American Library Bureau, the Catalogue or

90

Paul Otlet

the Library of Congress in Washington) [3]; then by
bibliographies printed on cards (International Institute of Bibliography, Concilium Bibliographicum)
[4]; next, indices of species have been published on
cards (Index Speciorum) [5]. We have moved from
the small card to the large card, the leaf, and have
witnessed compendia abandoning the old form for
the new (Jurisclasseur, or legal digests in card form).
Even the idea of the encyclopedia has taken this
form (Nelson’s Perpetual Cyclopedia [6]).
Theoretically and technically, we now have in
the Repertory a new instrument for analytically or
monographically recording data, ideas, information. The system has been improved by divisionary cards of various shapes and colours, placed in
such a way that they express externally the outline
of the classification being used and reduce search
time to a minimum. It has been improved further
by the possibility of using, by cutting and pasting,
materials that have been printed on large leaves o

been made to improve classification. These have taken three principal directions: classification studied as an activity
of the mind; the general classification and sequence
of the sciences; the systematization appropriate to
each discipline. The idea of order, class, genus and
species has been studied since Aristotle, in passing
by Porphyrus, by the scholastic philosophers and by
modern logicians. The classification of knowledge
goes back to the Greeks and owes much to the contributions of Bacon and the Renaissance. It was posed
as a distinct and separate problem by D’Alembert
and the Encyclopédie, and by Ampère, Comte, and
Spencer. The recent work of Manouvrier, Durand
de Cros, Goblot, Naville, de la Grasserie, has focussed on various aspects of it. [8] As to systematics,
one can say that this has become the very basis of
the organisation of knowledge as a body of science.
When one has demonstrated the existence of 28 million stars, a million chemical compounds, 300,000

92

Paul Otlet

vegetable species, 200,000 animal species, etc., it is
necessary to have a means, an Ariadne’s thread, of
finding one’s way through the labyrinth formed by
all these objects of study. Because there are sciences of beings as well as sciences of phenomena, and
because they intersect with each other as we better
understand the whole of reality, it is necessary that
this means be used to retrieve both. The state of development of a science is reflected at any given time
by its systematics, just as the general classification
of the sciences reflects the state of development of
the encyclopedia, of the philosophy of knowledge.
The need has been felt, however, for a practical
instrument of classification. The classifications of
which we have just spoken are constantly changing, at least in their detail if not in broad outline. In
practice, such instability, such variability which is
dependent on the moment, on schools of thought
and individuals, is not acceptable. Just as the Repertory

of Bibliography, which was doing this work,
was part of the invaded territory.
In its latest state, the Decimal Classification has
become an instrument of great precision which
can meet many needs. The printed tables contain
33,000 divisions and they have an alphabetical index consisting of about 38,000 words. Learning is
here represented in its entire sweep: the encyclopedia of knowledge. Its principle is very simple. The
empiricism of an alphabetical classification by subject-heading cannot meet the need for organising
and systematizing knowledge. There is scattering;
there is also the difficulty of dealing with the complex expressions which one finds in the modern terminology of disciplines like medicine, technology,
and the social sciences. Above all, it is impossible
to achieve any international cooperation on such
a national basis as language. The Decimal Classification is a vast systematization of knowledge, “the
table of contents of the tables of contents” of all

94

Paul Otlet

treatises. But, as it would be impossible to find a
particular subject’s relative place by reference to
another subject, a system of numbering is needed.
This is decimal, which an example will make clear.
Optical Physiology would be classified thus:
5 th Class
3rd Group
5th Division
7th Sub-division

Natural Sciences
Physics
Optics
Optical Physiology

or 535.7
This number 535.7 is called decimal because all
knowledge is taken as one of which each science is
a fraction and each individual subject is a decimal
subdivided to a lesser or greater degree. For the sake
of abbreviation, the zero of the complete number,
which would be 0.5357, has been suppressed because
the zero would be repeated in front of each number.
The numbers 5, 3, 5, 7 (which one could call five hundred and thirty-five point seven and which could
be arranged in blocks of three as for the telephone,
or in groups of twos) form a single number when
the implied words, “class, group, division and subdivision,” are ut

is less
well known: the combination of various classification numbers whenever there is some utility in expressing a compound or complex heading. In the
social sciences, statistics is 31 and salaries, 331.2. By
a convention these numbers can be joined by the
simple sign : and one may write 31:331.2 statistics
of salaries.01
This indicates a general relationship, but a subject also has its place in space and time. The subject
may be salaries in France limited to a period such as
the 18th century (that is to say, from 1700 to 1799).
01 The first ten divisions are: 0 Generalities, 1 Philosophy, 2
Religion, 3 Social Sciences, 4 Philology, Language, 5 Pure
Sciences, 6 Applied Science, Medicine, 7 Fine Arts, 8 Literature, 9 History and Geography. The Index number 31 is
derived from: 3rd class social sciences, 1st group statistics. The
Index number 331.2 is derived from 3rd class social sciences,
3rd group political economy, 1st division topics about work,
2nd subdivision salaries.

96

Paul Otlet

The sign that characterises division by place being
the parenthesis and that by time quotation marks
or double parentheses, one can write:
33:331.2 (44) «17» statistics — of salaries — in
France — in the 17th century
or ten figures and three signs to indicate, in terms
of the universe of knowledge, four subordinated
headings comprising 42 letters. And all of these
numbers are reversible and can be used for geographic or chronologic classification as well as for
subject classification:
(44) 31:331.2 «17»
France — Statistics — Salaries — 17th Century
«17» (44) 31:331.2
17th Century — France — Statistics — Salaries
The subdivisions of relation and location explained
here, are completed by documentary subdivisions
for the form and the language of the document (for
example, periodical, in Italian), and by functional
subdivisions (for example, in zoology all the divisions by species of animal being subdivided by biological aspects). It follows by virtue of the law o

ulness of such a
classification to the Repertory. It has rid us of the
difficulty of not having continuous pagination. Cards
to be intercalated can be placed according to their
class number and the numbering is that of tables
drawn up in advance, once and for all, and maintained with an unvarying meaning. As the classification has a very general use, it constitutes a true
documentary classification which can be used in
various kinds of repertories: bibliographic repertories; catalogue-like repertories of objects, persons,
phenomena; and documentary repertories of files
made up of written or printed materials of all kinds.
The possibility can be envisaged of encyclopedic
repertories in which are registered and integrated
the diverse data of a scientific field and which draw
for this purpose on materials published in periodicals. Let each article, each report, each item of news
henceforth carry a classification number and, automatically, by clipping, encyclopedias on cards can

98

Paul Otlet

be created in which all the results of international
scientific cooperation are brought together at the
same number. This constitutes a profound change
in the technology of the Book, since the repertory
thus formed is simultaneously a constantly up-dated book and a cooperative book in which are found
printed elements produced in all locations.
•••
4. If we can realize the third idea, the Office of Documentation, then reform will be complete. Such an
office is the old library, but adapted to a new function. Hitherto the library has been a museum of
books. Works were preserved in libraries because
they were precious objects. Librarians were keepers.
Such establishments were not organised primarily
for the use of documents. Moreover, their outmoded
regulations if they did not exclude the most modern
forms of publication at least did not admit them.
They have poor collections of journals; collections
of newspapers are nearly nonexistent; photographs,
films, phonograph discs have no

tracts together by subject; catalogues; chronological
repertories of facts or alphabetical ones of names;
encyclopedic repertories of scientific data, of laws,
of patents, of physical and technical constants, of
statistics, etc. All of these repertories will be set up
according to the method described above and arranged by the same universal classification. As soon
as an organisation to contain these repertories is
created, the Office of Documentation, one may be
sure that what happened to the book when libraries
first opened — scientific publication was regularised
and intensified — will happen to them. Then there
will be good reason for producing in bibliographies,
catalogues, and above all in books and periodicals
themselves, the rational changes which technology and the creative imagination suggest. What is
still an exception today will be common tomorrow.
New possibilities will exist for cooperative work
and for the more effective organisation of science.

5. Repertory, Classification, Office of Documentation are therefore the three related elements of a
single reform in our methods of registering scientific discoveries and making them available to the
greatest number of people. Already one must speak
less of experiments and uncertain trials than of the
beginning of serious achievement. The International Institute of Bibliography in Brussels constitutes
a vast intellectual cooperative whose members are
becoming more numerous each day. Associations,
scientific establishments, periodical publications,
scientific and technical workers of every kind are
affiliating with it. Its repertories contain millions of
cards. There are sections in several countries02 . But
this was before the War. Since its outbreak, a movement in France, England and the United States has
been emerging everywhere to improve the organisation of the Book. The Office of Documentation has
been suggested as the solution for the requirements
that have been discussed.
It is important that the world of science and
technology should support this movement and
above all that it should endeavour to apply the new
methods to the works which it will be necessary to
re-organise. Among the most important of these is
the International Catalogue of Scientific Literature,
that fine and great work begun at the initiative of the
Royal Society of London. Until now, this work has
02 In France, the Bureau Bibliographique de Paris and great
associations such as the Société pour l’encouragement de
l’industrie nationale, l’Association pour l’avancement des
sciences, etc., are affiliated with it.

the same kind: it has not recognised the value of a
card repertory or a universal classification. It must
recognise them in the future.03 ❧

des sciences,” Revue scientifique 58 (1918): 236-241.
[2] The International Catalogue of Scientific Literature, an enormous work, was compiled by a Central Bureau under the
sponsorship of the Royal Society from material sent in from
Regional Bureaus around the world. It was published annually beginning in 1902 in 17 parts each corresponding to
a major subject division and comprising one or more volumes. Publication was effectively suspended in 1914. By the
time war broke out, the Universal Bibliographic Repertory
contained over 11 million entries.
[3] For card publication by the Library Bureau and Library of
Congress, see Edith Scott, “The Evolution of Bibliographic
Systems in the United States, 1876–1945” and Editor’s Note
36 to the second paper and Note 5 to the seventh paper in
International Organisation and Dissemination of Knowledge; Selected Essays of Paul Otlet, translated and edited by
W. Boyd Rayward. Amsterdam: Elsevier, 1990: 148–156.
[4] Otlet refers to the Concilium Bibliographicum also in Paper
No. 7, “The Reform of National Bibliographies...” in International Organisation and Dissemination of Knowledge; Selected
Essays of Paul Otlet. See also Editor’s Note 5 in that paper
for the major bibliographies published by the Concilium
Bibliographicum.
[5] A possible example of what Otlet is referring to here is the
Gray Herbarium Index. This was “planned to provide cards
for all the names of vascular plant taxa attributable to the

Transformations In The Bibliographical
Apparatus Of The Sciences

103

Western Hemisphere beginning with the literature of 1886”
(Gray Herbarium Index, Preface, p. iii). Under its first compiler, 20 instalments consisting in all of 28,000 cards were
issued between 1894 and 1903. It has been continued after
that time and was for many years “issued quarterly at the
rate of about 4,000 cards per year.” At the time the cards
were reproduced in a printed catalogue by G. K. Hall in 1968,
there were 85 subscribers to the card sets.
[6] Nelson’s Perpetual Loose-Leaf Encylcopedia was a popular,
12-volume work which went through many editions, its
principle being set down at the beginning of the century.
It was published in binders and the publisher undertook to
supply a certain number of pages of revisions (or renewals)
semi-annually after

lcopedia on the Card-Index System,” in the Scientific American 109 (1913): 213. The Berlin
Correspondent of the journal reports a proposal made in
Berlin which contains “an idea, in a sense ... already carried
out in an American loose-leaf encyclopedia, the publishers
of which supply new pages to take the place of those that
are obsolete” (Nelsons, an English firm, set up a New York
branch in 1896. Publication in the U.S. of works to be widely
circulated there was a requirement of the copyright law.)
The reporter observes that the principle suggested “affords
a means of recording all facts at present known as well as
those to be discovered in the future, with the same safety
and ease as though they were registered in our memory, by
providing a universal encyclopedia, incessantly keeping
abreast of the state of human knowledge.” The “bookish”
form of conventional encyclopedias acts against its future
success. “In the case of a mere storehouse of facts the in-

104

Paul Otlet

finitely more mobile form of the card index should however
be adopted, possibly,” the author goes on making a most interesting reference, “in conjunction with Dr. Goldschmidt’s
Microphotographic Library System.” The need for a central
institute, the nature of its work, the advantages of the work
so organised are described in language that is reminiscent
of that of Paul Otlet (see also the papers of Goldschmidt
and Otlet translated in International Organisation and
Dissemination of Knowledge; Selected Essays of Paul Otlet).
[7] These machines were derived from Herman Hollerith’s
punched cards and tabulating machines. Hollerith had
introduced them under contract into the U.S. Bureau of
the Census for the 1890 census. This equipment was later
modified and developed by the Bureau. Hollerith, his invention and his business connections lie at the roots of the
present IBM company. The equipment and its uses in the
census from 1890 to 1910 are briefly described in John H.
Blodgett and Claire K. Schultz, “Herman Hollerith: Data
Processing Pioneer,” American Documentation 20 (1969):
221-226. As they observe, suggesting the accuracy of Otlet’s
extrapolation, “his was not simply a calculating machine,
it performed selective sorting, an operation basic to all information retrieval.”
[8] The history of the classification of knowledge has been treated
in English in detail by E.C. Richardson in his Classification
Theoretical and Practical, the first edition of which appeared
in 1901 and was followed by editions in 1912 and 1930. A
different treatment is given in Robert Flint’s Philosophy as
Scientia Scientarium: a History of the Classification of the
Sciences which appeared in 1904. Neither of these works
deal with Manouvrier, a French anthropologist, or Durand

de Cros. Joseph-Pierre Durand, sometimes called Durand
de Cros after his birth place, was a French physiologist and
philosopher who died in 1900. In his Traité de documentation,
in the context of his discussion of classification, Otlet refers
to an Essai de taxonomie by Durand published by Alcan. It
seems that this is an error for Aperçus de taxonomie (Alcan,
1899).
[9] General Hippolyte Sebert was President of the Association française pour l’avancement des sciences, and the Société d’encouragement pour l’industrie nationale. He had
been active in the foundation of the Bureau bibliographique
de Paris. For other biographical information about him see

So we won the battle but lost the war. By “we”, I
mean those avant-gardes of the late twentieth century whose mission was to free information from the
property form. It was always a project with certain
nuances and inconsistencies, but over-all it succeeded beyond almost anybody’s wildest dreams. Like
many dreams, it turned into a nightmare in the end,
the one from which we are now trying to awake.
The place to start is with what the situationists
called détournement. The idea was to abolish the
property form in art by taking all of past art and
culture as a commons from which to copy and correct. We see this at work in Guy Debord’s texts and
films. They do not quote from past works, as to do
so acknowledges their value and their ownership.
The elements of détournement are nothing special.
They are raw materials for constructing theories,
narratives, affects of a subjectivity no longer bound

efined by the urgency of mitigating the
effects of the planetary ecological crisis cannot be thought
apart.
