During the latter part of the year the Museum film "Through 

 These Doors," produced in 1950 (see page 22), was made available 

 to schools and various other organizations as an educational and a 

 public-relations service. The film was presented at one of the meet- 

 ings of the Conference of Woman's Clubs and a printed announce- 

 ment of the availability of the film was sent to schools throughout 

 the Chicago area. Shortly thereafter many requests for loan were 

 received, and as many requests as possible were honored. The film 

 is offered without charge to such groups, and so it is expected that 

 many additional opportunities to present the story of the Museum 

 to interested groups in many places will occur in the next year.
