A brief history of homophobia in Dewey decimal classification [View all]

[Behind the Aegis]

Libraries in more than 138 countries organise their resources according to Dewey decimal classification, or DDC for short. This proprietary system is the most widely used in the world. The DDC number reflects specific subject areas. Browsing shelves for books on similar topics, grouped together to make them easy to find, is both the beauty of and the frustration with the Dewey decimal system.

Once upon a time and yet not so long ago, LGBTI (lesbian, gay, bisexual, transgender and intersex) topics have variously been assigned to DDC categories such as Abnormal Psychology, Perversion, Derangement, as a Social Problem and even as Medical Disorders. Is it any wonder that someone browsing ‘similar’ library items in this area could feel alienated?

Addressing inclusion and alienation, in June 2015 Linda Rudell-Betts of the Los Angeles Public Libraries wrote a post on making sure its LGBTI Collection was assigned DDC call numbers from the twenty-second edition, so that its users are not confronted with earlier, demeaning classifications:

Dewey decimal classification (DDC) itself would assign lesbians, gay men, bisexual people and transgender people (LGBTI people) to a call number, 301.4157, as a kind of ‘abnormal sexual relations’ (modified fourteenth edition of the DDC).

Admittedly the fourteenth edition of DDC was published in 1942, but nonetheless, the spectre of earlier hurtful classifications can linger even when improved numbers have been assigned.
