title: Iesi.Collections official page
body: <p>Iesi.Collections.dll is shipped with nHibernate and has some good collections worth reusing. However I cannot find any official documentation page for them, and it might be dangerous to use unversioned undocumented library in the production, especially when a new nHibernate gets released breaking undocumented API.</p>
  
  <p>Where do I find the official page?</p>
