:This article was started in 2003 and was well developed by 2009 when the book was published. It is possible that the book copied Wikipedia. ~[[User:Kvng|Kvng]] ([[User talk:Kvng|talk]]) 00:04, 22 September 2018 (UTC)
::Actually, the book was [https://www.amazon.ca/Head-First-Design-Patterns-Brain-Friendly/dp/0596007124 first published in 2004]. But I would suspect that the book is quoting directly from the original GoF book or other more authoritative sources anyway. I did a comparison between the [https://books.google.ca/books?redir_esc=y&id=6oHuKQe3TjQC&q=Provide+an+interface+for+creating+families+of+related+or+dependent+objects+without+specifying+their+concrete+classes.#v=snippet&q=Provide%20an%20interface%20for%20creating%20families%20of%20related%20or%20dependent%20objects%20without%20specifying%20their%20concrete%20classes.&f=false 23 design pattern descriptions in the GoF book] and the descriptions in the table in the article, and there are a lot of close matches. (I didn't look at any other sources yet.) I'm not sure how much leeway there is wrt close paraphrasing in this context though, since the GoF definitions are pretty short.

::My subjective impressions:
::* 0 = exact match
::* 0.1 = very close match
::* 0.5 = somewhat different
::* 1 = pretty different
