The information about DDC number building and synthesized DDC numbers is not obvious nor easy to understand so a more detailed description would help to better understand DDC. --JakobVoss (talk)16:02, 25 March 2021 (UTC)[reply]

This is summarised under §3 Design. There needs to be a balance struck between three competing viewpoints:WP:COPYVIO – the tables are (I believe) copyright;WP:NOTHOWTO – the aim is to describe, not instruct and lastly a desire for WP to be as universal as possible. I might be persuaded to have a go at explaining in more detail if others would indicate where the balance is, alternatively would a librarian would take up the task?Martin of Sheffield (talk)16:32, 25 March 2021 (UTC)[reply]

Hi everyone! I was reviewing reference number 52 in relation to the section on the treatment of Homosexuality and I think the source was misread. It has an accurateWikipedia:As of tag, but the source itself provides further information regarding a classification change. The OCLC no longer recommends the use of 363.49, directly contradicting the claim made by the post. I'm still new here, so I wanted to post a note before going in to settle on an edit that would work.Whisperwind1242 (talk)00:23, 5 February 2024 (UTC)[reply]

I removed the statement that the Richardson copy was the only one extant. Comaromi is careful not to say that it is the only one and I can find at least 3 copies in HathiTrust - Harvard, UC Berkeley, and University of Michigan. The UC Berkeley one has some notes by J C Rowell, who himself developed a library classification that was used in the Berkeley library.Lamona (talk)02:39, 2 September 2025 (UTC)[reply]
