The publication of this Manual together with the Abridged
General Tables, did not by any means mark the end of the
Office's work on the classification. Indeed, it had only just
begun, for, in the period 1899 to 1905, the extended tables for
the whole classification were published in fascicules and in
special subject Manuals. The first of the fascicules was described
as «Summary of the Rules adopted for the Establishment
and Use of the Bibliographic Repertories*. 53 This was at
once a summary and a revision of the 1889 Manual and was
included in the IIB Annual for 1899, 54 and in each of the subject
manuals after that time until 1905.
The «Summary of the Rules» though substantially the same
as the Manual of 1899 did contain some modifications and
refinements. A number of signs of combination and abbreviation
were introduced to complement the signs used for the
common subdivisions. These, it was thought, would facilitate
the presentation of numbers in the tables and the writing and
reading of complex numbers to be used in a card repertory.
A single dash was used to indicate «subdivide like» for the
analytic subdivisions in the tables. A new procedure for
joining the numbers for works with multiple subjects was devised
also. Instead of joining them horizontally by plus signs,
it was suggested that they could be joined vertically bu the
use of a curved bracket, especially when a kind of factoring
n r o
i
g93 4 (05) (44—R.A.) would replace
385(05) (44—R.A.)+623.4(05) (44—R.A.) as the number assigned
to the French periodical Revue d'artillerie which dealt
with the army and with military materials. Another form this
number could take, however, was 358+623.4 (05) (44—R.A.).
The use of square brackets was especially recommended for
compound numbers where the colon was used but to each of
which had been added a common subdivision such as that of
form: [016:355] (05), a periodical bibliography of military
science, instead of 016:355(05) which would indicate a bibliography
of military periodicals. One extremely important addition
to the 1899 Manual was an auxiliary table of the common
analytic subdivisions for «point of view» to be used with the
tables for pure and applied science and for fine arts. Common
analytics were to be signalled by the use of a double zero.
They assured a common method of indicating «theory of»,
«economic aspects of», ^manufacture of», «materials used
for», and so on.
As important segments of the classification were completed,
they were published both as fascicules of the full edition of
the extended tables and in groups as special subject manuals
which comprised subject tables plus general fascicules such
as the «Summary of the Rules», tables of the common subdivi-
