<s>Not sure if this is the proper way to request a new list ([[ https://meta.wikimedia.org/wiki/Talk:Mailing_lists | meta suggests posting to bugzilla ]] :) ), but let's see.</s> Last week we started [[ https://pl.wikipedia.org/wiki/Wikiprojekt:Biblioteka | a new wikiproject at pl.wiki ]] for coordination of a large project devoted to librarians, libraries, books, bibliology and related topics. During [[ https://pl.wikimedia.org/wiki/Warsztat_dla_Stowarzyszenia_Bibliotekarzy_Polskich | wikiworkshops ]] I gathered a list of email addresses of people interested in taking part in the project, later this year we will hold additional workshops, in January we plan an editathon, there's a list of red links in the making - all in all the project is in full swing. I guess a public mailing list will be the easiest way to contact the participants.
The name most consistent would be wikipedia-pl-bibliotekarze@lists.wikimedia.org, as it's intended for librarians active on Polish Wikipedia (bibliotekarze means librarians in Polish).
The initial list administrator's address is krzysztof.machocki@wikimedia.pl (my official chapter's address), we'll add additional admins if need be. Secondary email address is j.potega@gmail.com (the group's leader on behalf of the Polish Librarians Association).
