5 Controversial Facts About Melvil Dewey and the Dewey Decimal System

Melvil Dewey, the inventor of the Dewey Decimal System, was born on December 10, 1851. Among other things, Dewey was a self-proclaimed reformer, so when working for the Amherst College library in the 1870s, he began to reclassify the facility’s books and how they were organized.

Though the system has gone through plenty of changes over the years, it’s still in wide use all over the world today and forever changed how libraries categorize their books. It has also caused a handful of controversies. In honor of Dewey Decimal Day, we dug into the organizational system—and its creator’s—dark side.

1. Melvil Dewey co-founded the American Library Association, but was forced out because of offensive behavior.

Melvil Dewey was an extremely problematic figure, even in his time. Though he co-founded the American Library Association (ALA), his often-offensive behavior—particularly toward women—didn’t make him a lot of friends.

In Irrepressible Reformer: A Biography of Melvil Dewey, author Wayne A. Wiegand described Dewey’s “persistent inability to control himself around women” as his “old nemesis.” In 1905, Dewey and several fellow ALA members took a cruise to Alaska following a successful ALA conference, with the purpose of discussing the organization’s future. Four women who were part of the trip ended up publicly accusing Dewey of sexual harassment—a rarity for the time. Within a year, Dewey was forced to step down from his involvement with the organization he helped to create.

2. Dewey required applicants to his School of Library Economy to submit photos.

In 1887, Dewey founded the School of Library Economy at Columbia College, where 90 percent of his students were female. It was long rumored that in addition to basic information like name, age, and educational background, Dewey required that prospective female students also submit their bust sizes. While this rumor was eventually proven to be false, Dewey did ask women to submit photos, often noting that “You cannot polish a pumpkin.”

3. A Howard University librarian reorganized Dewey's original system because of its racial bias.

Dewey’s personal biases spilled over into his creation, too, and it has taken sincere effort and work to right those wrongs. In the 1930s, Howard University librarian Dorothy Porter helped create a new system to undo the racist way Dewey’s system treated black writers. As Smithsonian reported:

All of the libraries that Porter consulted for guidance relied on the Dewey Decimal Classification. “Now in [that] system, they had one number—326—that meant slavery, and they had one other number—325, as I recall it—that meant colonization,” she explained in her oral history. In many “white libraries,” she continued, “every book, whether it was a book of poems by James Weldon Johnson, who everyone knew was a black poet, went under 325. And that was stupid to me.”

In addition to charges of racism, the DDS has also been accused of being homophobic. Early editions of the system classified books on or regarding LGBT issues under Abnormal Psychology, Perversion, Derangement, as a Social Problem, or even as Medical Disorders.

4. Its 'religion' section is skewed heavily toward Christianity.

The DDS section on religion starts at 200, and no other religion besides Christianity is covered until 290. Given that there are more than 4000 religions in the world, saving a mere 10 numbers for their classification doesn’t leave a lot of room for thorough coverage or exploration. Though some changes have been made as new editions of the system have been introduced, the process of restructuring the entire 200s is a project that has yet to be undertaken.

5. Critics of the system would prefer libraries take the Barnes & Noble approach.

The Dewey Decimal System is the most used library classification system, with the Chicago Tribune estimating that more than 200,000 libraries in 135 countries use it. But it’s far from a perfect system. As such, many libraries are experimenting with other organizational techniques, and many are dropping the DDS altogether.

The main complaint that public libraries have is that the Dewey Decimal System does not make reading exciting, and that there are other ways of categorizing and organizing books that are more like that of general bookstores. By doing away with the numbers (which are hard to remember for general library patrons), some libraries are classifying books simply by category and organizing by author—a system they've begun referring to as "Dewey-lite."

10 Fascinating Facts About the Thesaurus for National Thesaurus Day

Writers often turn to a thesaurus to diversify their vocabulary and add nuance to their prose. But looking up synonyms and antonyms in a thesaurus can help anyone—writer or not—find the most vivid, incisive words to communicate thoughts and ideas. Since January 18 is Thesaurus Day, we’re celebrating with these 10 fascinating facts about your thesaurus.

1. Its name comes from the Greek word for treasure.

Most logophiles consider the thesaurus to be a treasure trove of diction, but the word thesaurus really does mean "treasure." It derives from the Greek word thésauros, which means a storehouse of precious items, or a treasure.

2. You can call them thesauruses or thesauri.

How do you refer to more than one octopus? People say everything from octopuses to octopi to octopodes. Similarly, many people have trouble figuring out the correct plural form of the word thesaurus. Though thesauri is technically correct—it attaches a Latin suffix to the Latin word thēsaurus—both thesauri and thesauruses are commonly used and accepted today.

3. Early thesauruses were really dictionaries.

Ask a French scholar in the 16th century to see his thesaurus, and he'd gladly give you a copy of his dictionary. In the early 1530s, a French printer named Robert Estienne published Thesaurus Linguae Latinae, a comprehensive Latin dictionary listing words that appeared in Latin texts throughout an enormous span of history. And in 1572, Estienne's son Henri published Thesaurus Linguae Graecae, a dictionary of Greek words. Although the Estiennes's books were called thesauruses, they were really dictionaries comprised of alphabetical listings of words with their definitions.

4. A Greek historian wrote the first book of synonyms.

Philo of Byblos, a Greek historian and grammarian, wrote On Synonyms, a dictionary of synonyms that scholars consider to be the first ancient thesaurus. Dating to the late 1st century or early 2nd century CE, the book lists Greek words that are similar in meaning to each another. Sadly, we don’t know much more about On Synonyms because copies of the work haven’t survived over the centuries.

5. An early Sanskrit thesaurus was written in the form of a poem.

In the 4th century CE, an Indian poet and grammarian named Amara Sinha wrote The Amarakosha, a thesaurus of Sanskrit words. Rather than compile a boring list of similar words, Amara Sinha turned his thesaurus into a long poem. Divided into three sections—words relating to the divine, the earth, and everyday life—The Amarakosha contains verses so readers could memorize words easily. This thesaurus is the oldest book of its kind that still exists.

6. A British doctor wrote the first modern thesaurus.

Peter Mark Roget is the British doctor credited with authoring the first modern thesaurus. In 1805, he began compiling a list of words, arranged by their meaning and grouped according to theme. After retiring from his work as a physician in 1852, Roget published his Thesaurus of English words and phrases; so classified and arranged as to facilitate the expression of ideas and assist in literary composition. Today, Roget’s Thesaurus is still commercially successful and widely used. In fact, we celebrate Thesaurus Day on January 18 because Roget was born on this day in 1779.

7. The thesaurus has a surprising link to a mathematical tool.

The division between "words people" and "numbers people" is deep-seated. Many mathematicians may try to steer clear of thesauruses, and bibliophiles may avoid calculators, but the thesaurus is actually linked to a mathematical tool. Around 1815, Roget invented the log-log slide rule, a ruler-like device that allows users to easily calculate the roots and exponents of numbers. So while the inventor of the thesaurus was compiling words for his tome, he was also hard at work on the log-log slide rule. A true jack-of-all-trades.

8. The Oxford English Dictionary has its own historical thesaurus.

In 1965, a professor of English Language at Glasgow University suggested that scholars should create a historical thesaurus based on entries in the Oxford English Dictionary. The project was a massive undertaking, as people from multiple countries worked for 44 years to compile and classify words. Published in 2009, the Historical Thesaurus to the Oxford English Dictionary contains 800,000 words organized by theme and date. The thesaurus covers words and synonyms from Old English to the present day and lets readers discover when certain words were coined and how long they were commonly used.

9. One artist turned his love of words into a series of thesaurus paintings.

In 2014, the Jewish Museum in New York showed a survey of conceptual artist Mel Bochner’s art. Bochner had incorporated words and synonyms in his paintings for years—which were collectively referred to as the thesaurus paintings—featuring word paintings and lists of synonyms on canvas. The brightly colored paintings feature different groups of English and Yiddish synonyms. According to Bochner, Vietnam and Iraq war veterans cried after seeing his thesaurus painting Die, which features words and phrases such as expire, perish, succumb, drop dead, croak, go belly up, pull the plug, and kick the bucket.

10. There's an urban thesaurus for all your slang synonym needs

Urban Dictionary helps people decipher the latest slang terms, but where should you go when you need a thesaurus of slang? Urban Thesaurus, of course. The site, which is not affiliated with Urban Dictionary, indexes millions of slang terms culled from slang dictionaries, then calculates usage correlations between the terms. Typing in the word money, for example, gives you an eclectic list of synonyms including scrilla, cheddar, mulah, coin, and bling.

10 Endangered Alphabets You Should See Before It's Too Late

The Arabic and Simplified Chinese scripts aren't in danger of going anywhere anytime soon, but the same can't be said for Balinese, Mali, Pahawh (or Pahauh) Hmong, and the other 100-some alphabets that Vermont-based writer Tim Brookes has cataloged in his online Atlas of Endangered Alphabets, which is set for a soft launch on January 17. The featured alphabets—which Brookes has loosely defined to include writing systems of all sorts—are vanishing for varied reasons, including government policies, war, persecution, cultural assimilation, and globalization.

“The world is becoming much more dependent on global communications and those global communications take place in a relatively small number of writing systems—really something between 15 and 20,” Brookes tells Mental Floss. “And because that’s the case, all the others are to some degree being eroded.”

The atlas will include a bit of background information about each alphabet as well as links to any organizations attempting to revive them. By creating a hub for these alphabets, Brookes hopes to connect people who want to preserve their language and culture, while also showing the world how beautiful and intricate some of these scripts—including the 10 below—can be.

1. Cherokee

Although the Manataka American Indian Council says an ancient Cherokee writing system may have existed at one point but was lost to history, Cherokee was more or less a spoken language up until the early 19th century. Around 1809, a Cherokee man named Sequoyah started working on an 86-character writing system known as a syllabary, in which the symbols represent syllables. Most remarkably, Sequoyah himself had never learned how to read. At the time, many Native Americans deeply distrusted writing systems, and Sequoyah was put on trial for witchcraft after tribal leaders caught wind of his new creation. However, once they realized that written Cherokee could be used to preserve their language and culture, they asked Sequoyah to start teaching the syllabary. “The Cherokee achieved 90 percent literacy more rapidly than any other people in history that we know of,” Brookes says. “[Sequoyah’s syllabary] is one of the greatest intellectual achievements of all time.”

After a period of decline in the years following the Indian Removal Act of 1830, Cherokee language education saw somewhat of a revival in the late 20th century. The predominance of English and the Latin alphabet has made these efforts an uphill battle, though. Brookes says it’s difficult to find people who can teach the script, and even among Cherokee translators, few are confident in their grasp of the writing system.

2. Inuktitut

Nine different writing systems are used among Canada’s 59,500 Inuit. Many of these are based on the Latin alphabet, but the one shown above uses syllabics that were first introduced by European missionaries in the 19th century. Since it’s difficult and costly to represent each of these writing systems in official documents, many Inuit officials write and hold meetings in English, all but ensuring the demise of their mother tongue. However, Canada’s national Inuit organization, the Inuit Tapiriit Kanatami, is now in the process of developing one common script for all Inuit. “Our current writing systems were introduced through the process of colonization,” the organization writes on its website. “The unified Inuktut [the collective name for Inuit languages] writing system will be the first writing system created by Inuit for Inuit in Canada.” It remains to be seen what that script will look like.

3. Glagolitic

It’s widely believed that Glagolitic, the oldest known Slavic script, was invented by missionaries Saint Cyril and Saint Methodius around 860 CE in an effort to translate the Gospels and convert the Slavs to Christianity. The name Glagolitic stems from the Old Church Slavonic word glagolati, meaning to speak. Some of the symbols were lifted from Greek, Armenian, and Georgian, while others were entirely new inventions. Nowadays, academics are typically the only ones who can decipher the script, but some cultural institutions have made efforts to preserve its legacy. In 2018, the National and University Library in Zagreb launched an online portal containing digitized versions of Glagolitic texts. In addition to being a source of Croatian heritage and pride, the alphabet has also become an object of tourist fascination. Visitors can view monuments containing Glagolitic symbols along the Baška Glagolitic Path on the Croatian island of Krk. And in Zagreb, the capital city, it’s not hard to find gift shops selling merchandise adorned with Glagolitic writing. However helpful this may be to the tourism sector, it's no guarantee that more Croatians will want to start learning the script.

4. Mandombe

The Mandombe script

This African script is unusual for several reasons. For one, the Mandombe alphabet reportedly came to David Wabeladio Payi—a member of the Kimbanguist church in the Democratic Republic of Congo—in a series of dreams and spiritual encounters in the late ‘70s. One day, he was looking at his wall when he noticed that the mortar between the bricks seemed to form two numbers: five and two. He believed these were divine clues, so he set out to create a series of symbols based off those shapes. Eventually, he assigned the symbols phonographic meaning and turned it into an alphabet that could be used by speakers of the Kikongo and Lingala languages. Perhaps most remarkably, the pronunciation changes depending on how the symbols are rotated. “It’s one of about three writing systems in the world where that’s true,” Brookes says. Unlike most of the other alphabets on this list, Mandombe is growing in popularity rather than declining. However, because it’s primarily being taught in Kimbanguist schools and used only for religious texts, it will be a challenge to convince the rest of the population to start using it. Elsewhere in the country, the Latin alphabet is used (French is the official language). “What it’s up against is, in essence, exactly the same forces that a declining script is up against,” Brookes says. For this reason, many new alphabets can be considered endangered.

5. Ditema tsa Dinoko

In a similar vein, Ditema tsa Dinoko is also a minority script, and it's too new to tell if it will stick around. A team of South African linguists, designers, and software programmers invented this intricate, triangular-shaped alphabet in just the last decade in hopes of forging a single script that could be used by speakers of indigenous languages in South Africa, Botswana, Zimbabwe, and Mozambique. Because the symbols were inspired by artworks and beadwork designs that are typical of the region, the alphabet is also a celebration of culture. “One of the really interesting features of African alphabets is how deeply embedded they are in what we would call graphic design,” Brookes says. “Instead of imitating the shapes or structures or layout of other writing systems, such as our alphabet, they often start from a completely different point of view and draw on designs that are found in war paintings, weaving textiles, pottery, and all of those other available graphic elements.” The colors used in the alphabet aren't necessary to understand the script, but they hark back to the alphabet's artistic origins while also functioning as a kind of font. For instance, different writers may use different colors to give their text "a certain feel or emotional resonance," Brookes says.

6. Mandaic

This ancient, mystic script dates back to the 2nd century CE and is still being used by some Mandaeans in Iraq and Iran. According to mythology, the language itself predates humanity, and the script was historically used to create religious texts. Charles Häberl, now an associate professor of Middle Eastern languages and literatures at Rutgers University, wrote in a 2006 paper that Mandaic is “unlike any other script found in the modern Middle East." And unlike most scripts, it has changed very little over the centuries. Despite its enduring quality, many of the speakers in Iraq have fled to other countries since the U.S. invasion in 2003. As these speakers assimilate into new cultures, it becomes more challenging to maintain their linguistic traditions.

7. Lanna

According to Brookes, the Lanna script was primarily used during the time of the Lanna Kingdom in present-day Thailand from the 13th century to the 16th century. It’s still used in some regions of northern Thailand, but faces stiff competition from the predominant Thai script. The word Lanna translates to "land of a million rice fields." The script is one of Brookes’s personal favorites as far aesthetics are concerned. “It is so extraordinarily fluid and beautiful,” he says. “They developed this script to indicate not only consonants, but then the consonants have vowel markings and other consonant markings and tonal markings both above and below the main letters, and so you have this amazingly joyous and elaborate writing system, and it’s like a pond of goldfish. Everything is just curving around and swimming in all these different directions.”

8. Dongba

Members of the Naxi ethnic minority in China’s Yunnan province have been using this colorful pictographic script for well over 1000 years. The pictures stand for tangible objects like mud, mountains, and high alpine meadows, as well as intangible concepts such as humanity and religion [PDF]. Historically, it was mainly used by priests to help them remember their ceremonial rites, and the word Dongba means "wise man." However, the script has undergone something of a revival in recent years, having been promoted by people working in the arts and tourism industries. It’s also taught in some elementary schools, and it remains one of the few pictographic scripts that’s still in use today. At the same time, Brookes says he's seen little evidence of efforts "to create a circumstance where the script is actually used in a functional, everyday fashion." With the predominant Chinese script looming large throughout much of the country, Dongba's days may be numbered.

9. Tibetan

Some of the world’s alphabets and languages are endangered for political reasons. Tibetan is perhaps the best-known example of that. The Chinese government has cracked down on language instruction in recent years, with the aim of promoting Mandarin, the predominant language—although some have argued this policy comes at the expense of minority languages. In Tibet, many schools now conduct the bulk of their lessons in Mandarin, and Tibetan might be taught in a separate language course. Chinese officials put a Tibetan activist on trial in January 2018 for “inciting separatism”—partly because he criticized the government’s policies on Tibetan language education. He was sentenced to five years in prison. In general, “the story behind endangered alphabets is almost never a pleasant or cheerful one, so that’s the human rights side of it,” Brookes says.

10. Mongolian

Some have likened the appearance of the traditional Mongolian script to a kind of vertical Arabic. The script traveled to Mongolia by way of a Turkic ethnic group called the Uighurs in the 1100s. Beginning with Genghis Khan, Mongol leaders used the script to record historic events during their reign. Later, when Mongolia became a Soviet satellite state, the country started using the Cyrillic alphabet in the 1940s, and the traditional script was largely cast aside. The traditional alphabet is still used in inner Mongolia and is returning to Mongolia, and the renaissance of Mongolian calligraphy has bolstered its usage to some degree. Nonetheless, it, too, remains endangered.
