As I have easy memorization skills, I thought it would be fun to learn all the facts from an encyclopedia.

Unfortunately, I can't find any that meet my criteria:

  • Be made up of a single file (plain text or pdf)
  • Be relatively recent (say after 2015)
  • Be sufficiently complete (at least 2000 a4 pages)

Do you know of any such encyclopedia?


  • It doesn't have to be free
  • Any common language will do the trick
  • Wikipedia English version has 5,896,411 articles. Do you think 2000 pages would be enough? – scaaahu Jul 29 at 11:53
  • And Wikipedia lets you export a book of selected articles as PDF: en.wikipedia.org/w/… (although the options seems to be temporarily out of service at the moment) – Erwan Jul 29 at 11:55

    There's the Stacks project of algebraic geometry, which can be found as a single pdf, but its length is around 6000 pages if I remember correctly. – Evariste Jul 29 at 11:55
  • I definitely won't export 5 million articles. The Stacks Project is too specific but thanks :) – Blincer Jul 29 at 11:58

    I suggest Wookiepedia, which has a lot of facts and an enthusiastic audience! – Trusly Jul 29 at 23:50

I think you're unlikely to find something newer than 2015 for free without involving piracy in some way.

I suggest that, in order to get a relatively recent up-to-date version, you memorise the 2002 Encyclopedia Britannica Concise version which is available at archive.org:


And also the 1823 version, which will surely be a fascinating educational experience:


Having a look through archive.org in general will cede you a lot of interesting results.
