### Augmenting Human Intellect: A Conceptual Framework (1962)
The Reference to Doug Engelbart's 1962 research report Augmenting Human Intellect: A Conceptual Framework, introduced here https://en.wikipedia.org/wiki/Douglas_Engelbart#SRI_and_the_Augmentation_Research_Center, is obsolete and should be corrected. The link to his report should be https://dougengelbart.org/pubs/augment-3906.html, and a separate link to the most recent archive version of 2-Jun-2022 on Internet Archive https://web.archive.org/web/20220602190201/https://www.dougengelbart.org/pubs/augment-3906.html -  I have recently overhauled the referenced report on dougengelbart.org to correct many errors and ommissions that had been introduced in the original scanning and subsequent rendering to html since 1997(!) MouseSite version. By matching the text back to the original printed archive I have made numerous spelling corrections, instances of enhanced text (underlined for emphasis in the original, now italicized in the digital), adding back in omitted text such as Forward, Abstract, plus a (clickable) detailed Table of Contents, and rescanning images whose original scans had introduced some errors. Yay for Internet Archive, there is now a 2-Jun-2022 archive of the corrected version of the report to link to instead of the archived obsolete version. The desired Reference format is shown in the Wiki article on Intelligence Amplification https://en.wikipedia.org/wiki/Intelligence_amplification#References items #2 and #3 which do point to the official version on dougengelbart.org and separately link to the Archived version although as of this date they have yet to update that "Archived" link to the 2-Jun-2022 archive Cengelbart (talk) 17:13, 8 June 2022 (UTC)

The page Purple Numbers redirects here, without any mention of the term in the article.  Is this right?  Should something be added to the page? YorkshireLad (talk) 12:22, 15 May 2019 (UTC)

I found this website that mentions purple numbers and Engelbart [1]. It seems obscure. --Frmorrison (talk) 20:48, 21 May 2019 (UTC)
YorkshireLad, Frmorrison - I found this strange, too therefore I have opened a deletion review request to restore the standalone article. After a bit of research I found quite a bit of stuff written about purple numbers on the Web.  « Saper // @talk »  14:37, 29 December 2020 (UTC)
Saper, Thanks for the ping; I don't have anything to add to your DRV atm but I'll keep an eye on it.  :-) YorkshireLad  ✿  (talk) 14:46, 29 December 2020 (UTC)
@Saper: regardless of the outcome of the DRV, it would be helpful to have a mention of purple numbers on this article: in the short term it would resolve the confusing redirect, and, if undeletion goes through (either through DRV or through draft-then-AfC) it would create a convenient place to create a link to avoid the recreated article being an orphan (one could potentially add a red link, but I think that would be discouraged through WP:REDNO).  I tried to add a sentence or two, but the problem I've had is that I can't find any reliable sources talking about this.  (The best I can do is Frmorrison's link, and that seems to be a personal website, which in any case doesn't quite say that Engelbart invented a concept called "purple numbers".  It says he had a website that had purple numbers on it, and that he came up with a similar concept which that website's owner has implemented.)  Looking at the history of the WP:BLARred article, there are no reliable sources in there either: the only reference is itself another wiki.  Have you had any luck finding sources?  (If we collectively draw a blank, it would seem to suggest the solution is to nominate the redirect at WP:RfD.)  YorkshireLad  ✿  (talk) 00:40, 2 January 2021 (UTC)
Christina Engelbart here (Cengelbart (talk)) pinging @Saper:, @YorkshireLad:, @Frmorrison: -- appreciate your diligence! I agree Purple Numbers should have its own page, and/or redirect to the NLS (computer system) article and not this bio article.
I can confirm that "Purple Numbers" did indeed originate in Doug Engelbart's group in the mid-1990s. Building directly on his NLS/Augment software, under a modest DARPA grant purpose to build a browser-style client UI we called VAT to better demo Augment's key features like fine-grained addressability.  I helped spec this UI under this contract, which enabled us finally to add in proportional space fonts and font colorization, text highlighting, scrolling Windows-style file windows, etc. It was my idea to colorize the Augment-supplied address numbers to set them apart visually from the file content. After experimenting for several hours with different colors and intensities, I landed on a shade of orchid purple. You can see the completed UI demonstrated in Augment Demos "2008 Christina" -- showing the very first instance of Purple Numbers. That's Augment software displayed through the VAT client which is doing the colorizing. We very soon incorporated Purple Numbers into our website Bootstrap Institute, as documented here, which persists today. Importantly, today the numbers are flush to the right margin which we wished we could have implemented way back then.
Both Peter Yim and Eugene Kim, who were very involved in Doug's 2000 Colloquium at Stanford and subsequent OHS Working Group, definitively documented Purple Numbers at the time:
PurpleNumbers, by Peter Yim
An Introduction to Purple, by Eugene Kim
Both took stabs at implementing Purple Numbers for Wiki browsing. In 2005-2006 Eugene was hired into Doug's HyperScope project, which included Purple Numbers for fine-grained addressability, and co-presented The Augmented Wiki with Doug at subsequent conference. I'm not sure which of us coined the term "Purple Numbers" -- Eugene may recall.
Bottom line you/whoever can confidently glean from my writing above plus their two pieces, citing especially their two pieces, to flesh out a Purple Numbers page. (Cengelbart (talk) 22:41, 20 February 2024 (UTC) -- Christina Engelbart, Executive Director, The Doug Engelbart Institute.)
... and/or I publish short History of Purple Numbers at [https://dougengelbart.org] that you can cite. Cengelbart (talk) 15:14, 21 February 2024 (UTC)

The four points in guiding philosophy were not said by Engelbart. They seem to be a summation of a number of secondary articles that do not cite their sources. I have found a number of people quoting this online as Engelbart's words. The provenance of this sentiment seems to be citing his various talks:
http://www.dougengelbart.org/colloquium/sessions.html
http://dougengelbart.org/content/view/161/000/
https://stanford.edu/dept/SUL/sites/engelbart/engfmst1-ntb.html
There are many more out there. 
I have been looking but I haven't found him saying these things. To avoid further misquoting it should be made evident that these are a summation and not his specific words. Or the actual source should be cited here rather than secondary articles. This section is not incorrect as far as I can tell, and it sounds like something Engelbart would say. It is rather an abridgment of a summary of his reasoning.  — Preceding unsigned comment added by 142.244.213.153 (talk) 17:11, 20 September 2019 (UTC) 

Thierry Bardini in an early chapter of his work describes evolution of Engelbart's ideas extensively, quoting, among others [Engelbart 1996]: "Douglas Engelbart: An Oral History. Four interviews conducted by H. Lowood and J. Adams, edited by T. Bardini. Stanford, Calif.: Stanford University Libraries. Available on-line at https://www-sul.stanford.edu/depts/hasrg/histsci/ssvoral/engelbart/start.html". Archived at http://web.archive.org/web/19990423125248/https://www-sul.stanford.edu/depts/hasrg/histsci/ssvoral/engelbart/start.html, it seems to be relocated to https://stanford.edu/dept/SUL/sites/engelbart/start1.html
There is also a much later formulation of his goals (http://web.archive.org/web/20060202024324/http://bootstrap.org/#3 - "Reasons for action"), but we refer here to his thoughts from 1950s (it could be changed of course).  « Saper // @talk »  23:35, 29 December 2020 (UTC)
Christina Engelbart here - I think I'm the one who contributed the four bullet points, definitely a summation, paraphrased from his myriad lectures, writings, and interviews. Some good sources for quotes:

The Introduction to Augmenting Human Intellect: A Conceptual Framework, D.C. Engelbart 1962 or any of his abridged versions
Engelbart Oral Histories (Stanford, Smithsonian, Computer History Museum)
The Augmented Knowledge Workshop, D.C. Engelbart, 1986 - his lecture and paper detailing his historic journey from epiphany to R&D, the Demo, and beyond  — Preceding unsigned comment added by Cengelbart (talk • contribs) 20:18, 14 February 2024 (UTC)
