So I decided to run a little test: take a [[random sample]] of 100 pages from [[Polish Wikipedia]] (4th largest Wikipedia with over 250,000 articles) and see how many have interwiki links to en wiki. The sample was taken by clicking the '[[Wikipedia:Random page|random page]]' button and noting down if article has an interwiki or not.

Results: out of 100 pages randomly selected on Polish Wikipedia, 72 had no interwiki links to en Wikipedia. (test as of 22 July 2006; WikipiediaWikipedia at that time had about 1,350,000 articles.)

Next, I decided to run a comparison of 'how many articles from a random encyclopedic publication' are missing on Wikipedia. The publication I selected, [[Polski Słownik Biograficzny]] (encyclopedia of famous Poles), was not completely random, but as far as I know there is no project dedicated to creating relevant stubs on en-wiki, and as one of my past projects there is a nice index at [[User:Piotrus/List of Poles]]. Note also that PSB is not a general knowledge encyclopedia but a specialized knowledge encyclopedia.

Results: as of 22 July 2006 out of selected 1000 entries of [[User:Piotrus/List of Poles/Kisielinski-Korzelinski]], about 30 entries have blue links (I ignored entries in need of disambigation, like 10 entries for [[Konrad]]). WikipiediaWikipedia at that time had about 1,350,000 articles.

=== Updates ===

Preeliminary analysis suggests coverage improvement of ~1% per year, with the estimate completion around turn of the century, assuming a linear growth model...

# 8 August 2007. I counted 34 blue links in 'Kisielinski-Korzelinski'. I counted two more for better stats: 'Olbrycht-Pawleta' - 37; 'Ebenberger-Gembicki' - 28 - so the ~3% still holds. WikipiediaWikipedia at that time had about 1,800,000 articles.

# 16 May 2008. 'Jesionowski-Kisielewski': 47. 'Skowron-Spiczakow': 23. 'Biergel-Bzowski': 36. Some interesting outliers, but it is safe to say ~3% still holds. WikipiediaWikipedia at that time had about 2,250,000 articles. WikipiediaWikipedia at that time had about 2,300,000 articles.

# 25 December 2008. 'Biergel-Bzowski': 36, 'Hoser-Jerzykowski': 46, 'Majnert-Michiels': 44. ~4%? WikipiediaWikipedia at that time had about 2,600,000 articles.

# 23 March 2009. 'Danielski-Dzwonkowski': 52. 'Lichtenstein-Majkowski': 67. 'Rutowicz-Schreiber'. 58 ~5%? WikipiediaWikipedia at that time had about 2,750,000 articles.

# 16 June 2009. 'Skowron-Spiczakow': 28. 'Przyalgowski-Retke': 65. 'Grodecki-Hoscki': 48. ~5%? WikipiediaWikipedia at that time had about 2,950,000 articles.

# 8 Dec 2010. 'Kisielinski-Korzelinski' 58. 'Olbrycht-Pawleta' 66; 'Ebenberger-Gembicki' 60. ~6%, and double the coverage of 2007. WikipiediaWikipedia at that time had about 3,500,000 articles.

# 23 May 2011. 'Gemma-Groddeck' 58; 'Rutowicz-Schreiber' - 70; 'Krzesinski-Lichtarowicz' - 61. Keeping at ~6%

# 25 Oct 2011. 'Abakanowicz-Bienkowski' 57, 'Korzeniewski-Krzesimowski' 67, 'Skowron-Spiczakow' - 37. No change.
