"A brief history of homophobia in Dewey decimal classification"
Interesting article in the Australian radical literary and cultural magazine, Overland.
The author, Doreen Sullivan, very briefly traces the controversies in using DDC (especially in the past). She draws heavily on a student paper, "Naming the Love That Dare Not Speak Its Name: A Look at How Gays and Lesbians are Classified in the Dewey Decimal Classification", by Michelle Drumm, written in 2000 (which is curiously dismissive of the work of pioneer Sanford Berman).
This is an important issue, as it allocates library materials to a particular place in 'knowledge', which may reflect all sorts of biases.
