Many libraries found this system too detailed and complex for their needs, and Cutter received many requests from librarians at small libraries who wanted the classification adapted for their collections. He devised the Expansive Classification in response, to meet the needs of growing libraries, and to address some of the complaints of his critics.<ref>For the Expansive Classification as a response to Cutter's critics, see: Miksa, Francis L., ed.

==Structure of the Expansive Classification==

The Expansive Classification uses seven separate schedules, each designed to be used by libraries of different sizes. After the first, each schedule was an expansion of the previous one,<ref>Miksa, Francis L., ed. ''Charles Ammi Cutter: Library Systematizer". Littleton, CO, Libraries Unlimited. 1977, p. 58.</ref> and Cutter provided instructions for how a library might change from one expansion to another as it grows.<ref>Cutter, C. A.

== Summary of schedules ==

===First classification===

The first classification is meant for only the very small libraries. The first classification has only seven top level classes, and only eight classes in all.

=== First classification ===

The first classification is meant for only the very small libraries. The first classification has only seven top -level classes, and only eight classes in all.total:

* '''A''' Works of reference and general works which include several of the following sections, and so could not go in any one.

Line 32 ⟶ 73:

* '''YF''' [[Outline of fiction|Fiction]]

=== Further classifications ===

Further expansions add more top -level classes and subdivisions. Many subclasses arranged systematically, with common divisions, such as those by geography and language, following a consistent system throughout.<ref>{{Cite web | url=https://archive.org/details/cu31924092476229 |title = Expansive classification|year = 1891}}</ref>

By the fifth classification all the letters of the alphabet are in use for top -level classes. These are:

* '''A''' General Works

Line 64 ⟶ 105:

* '''Z''' Book arts

These schedules were not meant to be fixed, but were to be adapted to meet the needs of each library. For example, books on the English language may be put in X, and books on language in general in a subclass of X, or this can be reversed. The first option is less logical, but results in shorter marks for most English language libraries.<ref>Cutter, C. A. [https://books.google.com/books?id{{r|n=L10oAAAAYAAJ&pg=PA1 ''Expansive Classification: Part I: The First Six Classifications'']. Boston, C. A. Cutter. 1891–93, -1891|p. =27.</ref>}}

==How ExpansiveConstruction Classificationof call numbers are constructed==

{{Expand section|citations and corrections|date=August 2011}}

Most call numbers in the Expansive Classification follow conventions offering clues to the book's subject. The first line represents the subject, the second the author (and perhaps title), the third and fourth dates of editions, indications of translations, and critical works on particular books or authors. All numbers in the Expansive Classification are (or should be) shelved as if in decimal order.

Line 72 ⟶ 113:

Size of volumes is indicated by points (.), pluses (+), or slashes (/ or //).

For some subjects a numerical geographical subdivision follows the classification letters on the first line. The number 83 stands for the United States&mdash;henceStates—hence, F83 is U.S. history, G83 U.S. travel, JU83 U.S. politics, WP83 U.S. painting. Geographical numbers are often further expanded decimally to represent more specific areas, sometimes followed by a capital letter indicating a particular city.

The second line usually represents the author's name by a capital letter plus one or more numbers arranged decimally. This may be followed by the first letter or letters of the title in lower-case, and/or sometimes the letters a, b, c indicating other printings of the same title. When appropriate, the second line may begin with a 'form' number&mdash;enumber—e.g., 1 stands for history and criticism of a subject, 2 for a bibliography, 5 for a dictionary, 6 for an atlas or maps, 7 for a periodical, 8 for a society or university publication, 9 for a collection of works by different authors.

On the third line a capital Y indicates a work about the author or book represented by the first two lines, and a capital E (for English&mdash;otherEnglish—other letters are used for other languages) indicates a translation into English. If both criticism and translation apply to a single title, the number expands into four lines.

=== Cutter numbers (Cutter codes) ===

{{Expand section|examples and additional citations|date=August 2011}}

One of the features adopted by other systems, including Library of Congress, is the Cutter number or Cutter code. It is an alphanumeric device to code text so that it can be arranged in alphabetical order using the fewest characters. It contains one or two initial letters and Arabic numbers, treated as a decimal. To construct a Cutter number, a cataloguer consults a Cutter table as required by the classification rules. Although Cutter numbers are mostly used for coding the names of authors, the system can be used for titles, subjects, geographic areas, and more.

|}

Initial letters Qa–Qt are assigned Q2–Q29, while entries beginning with numerals have a Cutter number A12–A19, therefore sorting before the first A entry.<ref>{{cite web|title=LC Cutter Tables |url=http://staff.library.mun.ca/staff/toolbox/tables/lccutter.htm |website=Queen Elizabeth II Libraries |publisher=Memorial University of Newfoundland |accessdateaccess-date=14 August 2014 |url-status=bot: unknowndead |archiveurlarchive-url=https://web.archive.org/web/20140814173419/http://staff.library.mun.ca/staff/toolbox/tables/lccutter.htm |archivedatearchive-date=14 August 2014 }}</ref>

So to make the three -digit Cutter number for "Cutter", youone would start with "C", then looking under ''other consonants'', find that "u" gives the number 8, and under ''additional letters'', "t" is 8, giving a Cutter number of "C88".
