This PDF documents proposed changes throughout the Dewey Decimal Classification (DDC)
stemming from the adoption of the APG (Angiosperm Phylogeny Group) III classification as the
basis for the DDC’s treatment of flowering plants.
We request comment from any interested party, to be sent to Rebecca Green ([email protected])
by 31 January 2016. Please include “Angiosperm review comments” in your subject line.
-------------------------------------------------------------Why is the DDC adopting a new basis for classifying angiosperms (flowering plants)? During
the latter half of the 20th century, biological classification turned from establishing taxa
predominantly on the basis of morphological similarities to establishing taxa predominantly on
the basis of shared ancestry / shared derived characters, with biological taxonomies mirroring
evolutionary relationships. Phylogenetic analysis typically underlies modern evolutionary
classifications, but has resulted in the development of many competing classifications. Within
the domain of flowering plants, different classification systems have been favored in different
countries. The Angiosperm Phylogeny Group, a global consortium of botanists, has addressed
this issue by developing a “consensus” classification that is monophyletic (i.e., its taxa include
all but only the descendants of a common ancestor). Now in its third version, the APG III
classification is considered relatively stable and useful for both research and practice (e.g., for
organizing plants in herbaria).
The development for flowering plants presented here is the culmination of DDC editorial work
over a span of several years. An early version revised 583–584 to make the schedule compatible
with the APG III classification, while trying to minimize relocations and using see references to
establish the APG III logical hierarchy. But the Dewey Editorial Policy Committee found the
result unsatisfying and recommended instead that the 583–584 development be brought into full
alignment with the APG III classification. A companion document, known as LAPG, which sets
forth a linear sequence of the families of APG III, was also consulted. (Former assistant editor
Giles Martin is responsible for the bulk of the underlying conceptual work of translating APG III
structure and LAPG order into DDC classes.)
-------------------------------------------------------------The Manual note at 583–584 Classification and common names of angiosperms (flowering
plants) has been completely revised and provides useful background:
The subdivisions of angiosperms (flowering plants) in 583–584 are defined by reference
to the article “An update of the Angiosperm Phylogeny Group classification for the
orders and families of flowering plants: APG III,” Botanical Journal of the Linnean
Society 161 (2009): 105–121.
Only the overall outline from early editions of the Dewey Decimal Classification is
retained, in which the eudicots of 583 precede the monocots of 584. Otherwise the
sequence of classes is guided by Haston et al., “The Linear Angiosperm Phylogeny
Group (LAPG) III: a linear sequence of the families in APG III,” Botanical Journal of the
Linnean Society 161 (2009): 128–131.
1
Only APG III families with sufficient literary warrant appear in the headings or notes of
583–584, while all APG III family names have been indexed to the appropriate classes.
Although non-APG names are no longer mentioned in the schedules, they continue to be
indexed, but at relocated numbers, if necessary. As non-APG names are derived from a
different system of classification, their fit may be only approximate.
Latin or Greek taxonomic names are given in the heading, while their English language
equivalents are given in a class-here note. Other Latin or Greek taxonomic names and
their English language equivalents are given in separate including and class-here notes.
Exercise caution in identifying orders and families of flowering plants by common
names; many such names are used for plants in several unrelated taxonomic groups.
Notes in the schedule linking the common names are not exhaustive.
-------------------------------------------------------------In the course of this revision, the Dewey Editorial Policy Committee encouraged the editors to
include more common names. Common names unfortunately are problematic. They are
especially vulnerable to complications of synonymy (a given plant may have more than one
common name) and polysemy (the same common name may be used to refer to several distinct
plants). The common names used may vary by region, language, and/or time. (These patterns
arise in part because common names may be based on physical attributes, similar physical
attributes may be present in various and widespread plant species, while specific plant species
are often subject to limited geographic distribution.) At the same time that some plants have
more than one common name, other plants have no common name at all.
Common names are common in the sense of belonging to everyday language, not necessarily in
the sense of being shared. Consequently, in some cases common names can prove confusing
even within a language, and they can cause outright havoc for translation.
Because of the problems associated with common names, the only way to disambiguate them
consistently is through the use of scientific names. Hence, the schedule now refers, for example,
to bluebells of family Asparagaceae to distinguish them from bluebells of family Boraginaceae
and bluebells of family Campanulaceae.
We have used the Encyclopedia of Life (eol.org) as our source for common/vernacular names:
Its coverage of taxonomic names is excellent; supply of vernacular names is both authoritative
and deliberate. While multilinguality is currently limited, its files are structured to support full
multilinguality.
-------------------------------------------------------------The pages that follow include changes made to different parts of the DDC, as indicated:
Manual: p. 4–6
Table: p. 7
Schedule: pp. 8–29
Relative Index: pp. 30–65

Symbols in the Relative Index have the following meanings (but can mostly be ignored):
•
•
•
•
E: Proposed electronic only
Ia: Mapped LCSH
N: Approved electronic only
P: Proposed print
Because Relative Index headings and mapped Library of Congress Subject Headings are
interfiled in the Relative Index given here (and not displayed separately, as they would [and
will] be displayed in WebDewey), when a Relative Index term and a mapped LCSH match, the
display is somewhat unusual. For example, in the following Relative Index segment,
the first entry for African violets at 635.93396 is for the mapped LCSH African violets. Directly
below that line is a line showing only the index number. This line corresponds to the indexing of
the Relative Index heading African violets at 635.93396.
The following schedule entries are included for context only: 561, 575, 577, 581, 615, 633, 634,
and 635.

577
577.3–.7 vs. 579–590
Ecology of dominant organisms in a specific kind of environment
Use 577.3–.7 for the ecology of dominant organisms (usually plants) of a specific ecological environment (biome). For example, use 577.4 (not 584.917) for the role of
grass in grasslands. Similarly, use 577.3 for the ecology of specific forest associations,
e.g., ecology of coniferous forest associations in Canada 577.30971 (not 585.0971 or
585.170971); and use 577.686 (not 597.17686) for fishpond ecology.
Use 579 or 580–590 only for works that emphasize the biology of the dominant kind
of organism, e.g., the biology of grass in grasslands 584.92 (not 584.9217), the biology
of fish found in fishponds 597.17636.
If in doubt, prefer 577.3–.7.
579–590
Taxonomic nomenclature and sources of information
Taxonomic nomenclature
The notes below mention several of the commonly recognized taxonomic levels used
in classifying organisms. The broadest is kingdom, followed (in order of increasing
specificity) by phylum or division, class, order, family, genus, species.
In the schedules for specific kinds of organisms, scientific terms are preferred in headings for taxonomic numbers below the kingdom level. Except in 583–584, if there is
an alternative scientific name still in current use, it is given in the heading in parentheses following the preferred term. If there are two or more alternative scientific names
in current use, the preferred term is given in the heading, and the alternative names
are given in a variant-name note. For example, Mycetozoa, Myxomycetes, Myxomycophyta, Myxomycota are given as variant names for Myxomycotina (slime molds) at
579.52. Most obsolete names have been dropped. If a common name is well established
in the literature but does not have a clear-cut corresponding scientific term (or terms),
the common name may be used alone, e.g., 598.412–.415 Ducks.
A scientific name given in a class-here note is usually that of a subordinate taxon that
comprises all or most of the members of the group in the heading. For example, under
583.986 Paracryphiales, the class here note gives Paracryphiaceae, the only family in
the order.
Except in 583–584, common names are linked to scientific names by parentheses when
they are generally understood to be exact equivalents. When two common names are
linked to a scientific name, a comma between them means that they are alternative common names, e.g., “(doves, pigeons)“ after Columbidae in the class-here note at 598.65.
An ”and“ means that the two groups with common names together comprise the scientific group, e.g., ”(fireflies and glowworms)“ after Lampyridae in the including note
at 595.7644. Common names that simply refer to well-known members of a scientific
class, however, are listed alphabetically in an including note.
With some plants and animals, the familiar name for families consists of the name of
a typical member or members plus the word “family,” e.g., Taxaceae (yew family) at
585.6. The typical member may be a single species or a large genus with hundreds of
species, but seldom approximates the whole of the family. Classifiers must not assume
that if the family approximates the whole of an order, the typical members do also.

Biology
579
An illustration of two terminology problems appears at 584.288 Laurales. The main
family of this order is Lauraceae, the laurel family, which encompasses ca. 90 percent
of the species of the order. The family is therefore given in a class here note, signifying that subdivisions can be added to the number for works on the family because it
approximates the whole of the order.
Only a few species of the laurel family, however, are individually known as laurels,
while several plants of other orders are also called laurels. Since it is useful to know
where to class comprehensive works on laurels, the including note reads, in part: “Including ... comprehensive works on laurels.” Being listed in an including note means
that laurels (even in its broadest sense encompassing all plants called laurels) do not
approximate the whole of the more than 3000 species in the order Laurales.
Some large classes of organisms have two including notes, for classifier convenience.
The first including note lists the scientific names of families or higher taxa and their
corresponding common names, the second the common names that do not correspond
with the given scientific names. (In 583–584, scientific names and common names are
always in separate including notes, as well as in separate class here notes.) Except in
583–584, genera are listed with the common names because so many have become common names.
Sources of taxonomic information
Taxonomic schedules usually follow the arrangement accepted in The New Encyclopaedia Britannica, 1989. Other works that often prove helpful are Synopsis and Classification of Living Organisms edited by Sybil P. Parker (McGraw-Hill, 1982), and Webster’s
Third New International Dictionary.
See also discussion at 579.24–.25; also at 579.3; also at 583–584; also at 599.
583–585 vs. 600
Interdisciplinary works on specific kinds of seed plants
Use 583–585 for works limited to the botany of useful plants, and for works giving significant treatment to species of no particular economic value. For example, use 583.34
for a works covering the 300 species of the buttercup family, and 583.9593 for a works
on peppers that covers all the species of Capsicum and other genera that are called peppers. Also use 583–585 when there are two or more uses in technology, or one such use
offset by an obvious botanical interest, e.g., 583.65 for oaks because oaks are useful as
ornamental trees as well as lumber trees, and 584.288 for laurels because the many wild
species of interest to botanists usually outweigh the few species that are well known
as ornamentals.
Use numbers in 600 for interdisciplinary works on most kinds of seed plants that have
a single dominant use. For example, use 615.321 for medicinal plants, 633.2–.3 for
forage plants, 635.9 for ornamental plants (635.933644 for roses), 641.33–.35 for food
plants (641.3411 for apples), 674 for lumber plants, and 677 for textile plants (677.21
for cotton).
The interdisciplinary number for most common plants is given in the Relative Index as
the number opposite the unindented term. Use 583–585 for interdisciplinary works on
plants that are not indexed, unless they belong in categories like those mentioned in the
preceding paragraph. If in doubt, prefer 583–585.

Manual on Use of Dewey Decimal Classification
583–584
Classification and common names of angiosperms (flowering plants)
The subdivisions of angiosperms (flowering plants) in 583–584 are defined by reference to the article “An update of the Angiosperm Phylogeny Group classification for the
orders and families of flowering plants: APG III” in Botanical Journal of the Linnean
Society 161 (2009): 105–121. Only the overall outline from early editions of the Dewey
Decimal Classification is retained, in which the eudicots of 583 precede the monocots
of 584. Otherwise the sequence of classes is guided by Haston et al., “The Linear Angiosperm Phylogeny Group (LAPG) III: a linear sequence of the families in APG III“
in Botanical Journal of the Linnean Society 161 (2009): 128–131.
Only APG III families with sufficient literary warrant appear in the headings or notes of
583–584, while all APG III family names have been indexed to the appropriate classes.
Although non-APG names are no longer mentioned in the schedules, they continue to
be indexed, but at relocated numbers, if necessary. As non-APG names are derived from
a different system of classification, their fit may be only approximate.
Latin or Greek taxonomic names are given in the heading, while their English language
equivalents are given in a class-here note. Other Latin or Greek taxonomic names and
their English language equivalents are given in separate including and class-here notes.
Exercise caution in identifying orders and families of flowering plants by common
names; many such names are used for plants in several unrelated taxonomic groups.
Notes in the schedule linking the common names are not exhaustive.
583 vs. 582.13
Angiosperms (Flowering plants) vs. Plants noted for their flowers
Use 583 for works on the taxonomic group called “flowering plants,” as found in
583–584. This group includes most plants that will be found in a typical vegetable garden. Use 582.13 for works largely limited to nondomesticated plants with attractive
flowers. These are the kind of plants that are found in nature, but that might also find a
place in flower gardens or flower books. If in doubt, prefer 583.
615.7 vs. 615.9
Pharmacokinetics vs. Toxicology
Use 615.704, or the number in 615.71–.78 for the system affected, for toxic effects and
interactions of drugs primarily of pharmacokinetic interest. However, use 615.9 when a
drug primarily of pharmacokinetic interest is considered a poison because it is so toxic
that a single inadvertent ingestion would cause serious complications or death, e.g.,
the pharmacokinetics of atropine (belladonna) 615.7 (not in any specific subdivision
because it affects several systems), but the toxicology of belladonna 615.95239593. If
in doubt, prefer 615.7.
