In addition to traditional awards celebrating best film, cinematography, actor/actress, etc. for each year's release of films, The Boston Society of Film Critics also intermittently selects a group of films which they consider to be the best "discoveries" or "rediscoveries" of past films which might have been misjudged or missed.
The lists comes from this parent page: www.bostonfilmcritics.org/content/past-award-winners (accessed 2017/08/17). The current awards stem from this page: www.bostonfilmcritics.org/content/bsfc-2016-awards-commendations-and-rediscoveries (same access date). I have organized this list directly from that page's ordering - which is to say the top-most films are the latest "rediscoveries" and the bottom are the oldest.
The ordering is no indication of relative perceived quality by any party, though the fact that these films are "discovered" would indicate an opinion of some good regard for all these films in general.
