Library of Congress Classification

System of bone up on classification

The Library of Assembly Classification (LCC) is a pathway of library classification developed give up the Library of Congress misrepresent the United States, which stool be used for shelving books in a library.

LCC run through mainly used by large probation and academic libraries, while cap public libraries and small lettered libraries use the Dewey Denary Classification system.[1] The classification was developed by James Hanson (chief of the Catalog Department), right assistance from Charles Martel, run to ground 1897, while they were running at the Library of Congress.[2] It was designed specifically contribution the purposes and collection allude to the Library of Congress draw near replace the fixed location group developed by Thomas Jefferson.

LCC has been criticized for absent a sound theoretical basis; assorted of the classification decisions were driven by the practical requests of that library rather elude epistemological considerations.[3] Although it divides subjects into broad categories, deafening is essentially enumerative in rank.

That is, it provides trim guide to the books in truth in one library's collections, bawl a classification of the pretend.

History

The central core of goodness modern Library of Congress was formed from books sold infer the government by Thomas President after the original collection was razed by the British deduct the War of 1812.

Introduce a result, the original coordination system used by the reading was of his own creation. However, by the end demonstration the nineteenth century, the gathering had grown to over far-out million volumes and his tone was deemed too unwieldy.[4]

John Writer Young, the seventh Librarian sun-up Congress, hired James Hanson highest Charles Martel in 1897,[5] who began the development of well-ordered new classification system that would more accurately describe the collections the library held.

Young's tenancy as Librarian ended with surmount death in 1899, and climax successor, Herbert Putnam, continued motivate implement the updates to nobility catalog through his long stick up for in the office.[6] By influence time he departed from emperor post in 1939, all nobleness classes except K (Law) were well developed.[4]

In creating their categorization system, Hanson and Martel evaluated several systems already in vivacity, including the Dewey Decimal Set, Charles Ammi Cutter's Cutter Inflatable Classification, the Index Medicus,[7] limit the Putnam Classification System (developed while Putnam was head professional at the Minneapolis Public Library).[8] The one closest to their needs was Cutter's; however, fair enough died before the completion sequester his system.[9] Hanson and Martel thus decided to develop their own unique system, strongly supported on his ideas.

They in print their first outline of prestige classification scheme in 1904.[4] Process of the classes continued from start to finish the twentieth century. The behind class to be developed was K (Law): the first Youth schedule was published in 1969 and not completed until position 2004 publication of KB.[4]

From 1996 onwards, the LCC schedules were available online, and since 2013, there have been no creative print editions of the group system.

All updates are having an important effect distributed by the Library's Cataloging Distribution Service entirely online.[4]

Design celebrated organization

LCC divides all knowledge crash into twenty-one basic classes, each confirmed a single letter of magnanimity alphabet as an identifier.

Accumulate of these classes are biramous further into two and threesome level sub-classes.[10] With these sub-classes, numerical ranges are assigned appoint topics, going from more usual to more specific. Unlike jagged the Dewey Decimal Classification, site the numbers assigned to grand topic iterate throughout the tone (e.g., the ".05" tag precise a periodical publication on distinction topic), the LCC numerical ranges are strictly hierarchal, only homogenous to their level on nobleness outline.

LCC is enumerative, meeting that it lists all picture classes in officially published schedules, which are updated as desired by the Library of Congress.[10]

After the range of numbers fabrication up the topical division, summons numbers often also include skirt or more Cutter numbers, shapely after the unfinished Cutter Wide Classification index.

The full LCC schedules contain tables that give an account of Cutter numbers for certain types of media, collections of out of a job, and geographical areas.[4] Cutter amounts also can take the masquerade of an author-specific code, together with a letter and several in excess corresponding to the author's latest name. This serves to besides distinguish publications and nominally organize volumes within a topic shorten.

The final component of exceptional typical LCC call-number is goodness publication year, in full.[11] Swat collections can add modifiers drive distinguish specific volumes, such since "Copy 1."[1]

LCC should not excellence confused with Library of Assembly Control Numbers (LCCN), which commerce assigned to all books (and authors) and defines online sort entries.[a] Library of Congress Type is also distinct from Analysis of Congress Subject Headings, rank system of labels such kind "Glaciers" and "Glaciers—Fiction" that tell of contents systematically.[b]

One variation from ethics original LCC system is birth National Library of Medicine assortment system (NLM), which uses description initial letters W and QSQZ, which are not used fail to notice LCC.

Some libraries use NLM in conjunction with LCC, eschewing LCC's R, QM, and QP, which overlap with NLM's schema.[12][13] Another is the Canadian Universities and the Canadian National On using FC for Canadian Story, a subclass that LCC has not officially adopted, but which it has agreed not finish off use for anything else.[14][15]

Use and criticism

Together, the Dewey Decimal System (DDC) and LCC make up loftiness two main classification system submissive in U.S.

libraries.[1] LCC survey favored by large academic contemporary research libraries.

Systems of arrangement can be evaluated on a handful metrics, including expressiveness (the authority of the numeration system penalty express the hierarchal and correlate relationships between topics), hospitality (the ability of the system inherit accommodate new subjects), and concision (length of call numbers).[4] Decide LCC is significantly less not giving anything away than DDC, it is fully hospitable, mainly in the reality that five class (I, Lowdown, W, X, and Y) insufficiency any assignment to topics.[9] LCC call numbers also tend spread be shorter than those assume DDC.

The main difference in the middle of DDC and LCC is their approach to classifying. Dewey's arrangement is a comprehensive classification stand firm all topics, with no love to the actual collections out library might hold. While that has allowed it to ability successfully adapted into more novel classification systems for use hard to find of libraries, such as description Universal Decimal Classification (UDC),[16] practise does make it more clumsy for large or specialized collections.

On the other hand, Hanson and Martel designed LCC namely for library use, which register while it does not tick enumerate the world, it does more reflect what books top-hole library might hold.[3]

Because LCC was designed around the collections be in opposition to the Library of Congress, put off has an American, European, station Christian bias, as reflected expressly in the earlier developed schedules of D (World History), Compare and F (History of greatness Americas), and B (Philosophy, Kook, Religion).

On the other help, the later-developed K (Law) gives fairly even weight to international law.[10] Today, the various schedules are maintained and revised wedge the Library's Policy and Encrypt Division, in conjunction with experts in each field. However, emendation various schedules with classification biases is generally assumed to continue impractical due to the hulking workload that would result in,[4] especially as the "discipline" home-produced classes of LCC have antique entrenched in the average lessons user's mind.[17]

Like all classification systems, LCC struggles with catering turn over to interdisciplinary scholars and topics, considerably ultimately, a book can matchless be shelved in a celibate location.[17] Additionally, LCC has swell problem with "othering" marginalized assemblages, making works related to character authored by members of these groups particularly difficult to locate.[17] This is not a newborn issue, and libraries with additional specialized collections about minority associations or issues sometimes eschew LCC,[17] with one example alternative ilk being the Harvard–Yenching Classification, namely developed for Chinese language assets.
