I am surprised that the article is listed only as being on mid-importance by WP:Poland. I would have thought that any article referenced by the main Poland article would be of high importance. Hawkeye7 (talk) 21:57, 17 April 2013 (UTC)Reply
Re comment 29 : The 'cite book' and 'cite web' templates use the ' url= ' parameter. Are you saying that the Url's contained in these all need to be deleted? -- Gwillhickers (talk) 00:20, 18 April 2013 (UTC)Reply
A few more comments. 1. Punctuation for dates and their format is incorrect/inconsistent--date-month-year is found in some paragraphs, month-date-year in others. I corrected a few comma errors for the first format, there may be more. 2. The use of hyphens also has a few errors here and there (I corrected one). 3. The bibliography is not in line with any format I know: bold print for last names is not acceptable in any format I know, and those entries are just odd in other ways, with "Url" as the text for URL links. Use of templates would make that disappear in one fell swoop. Some entries have years, others don't; Sužiedėlis has a page number so I presume a chapter/entry is cited but no title of such is given. Some entries have place names, others don't. Ottenberg is an article, but the title is in italics. One journal title is in all caps. I could go on--that entire section needs an overhaul and, again, the use of standard templates would go a long way to removing inconsistencies. Drmies (talk) 04:21, 18 April 2013 (UTC)Reply
Comment GA does not require compliance with the full MOS. However, any attempt to take the article to A class or FAC will require the MOS issues to be dealt with. Hawkeye7 (talk) 22:37, 20 April 2013 (UTC)Reply
