  OFFICE 
  LIBRARY. 
  

  

  The 
  growth 
  and 
  increasing 
  value 
  of 
  the 
  office 
  library 
  is 
  perhaps 
  

   not 
  fully 
  realized. 
  The 
  total 
  number 
  of 
  its 
  accessions 
  as 
  reached 
  

   this 
  year 
  now 
  numbers 
  27,100, 
  of 
  which 
  394 
  volumes 
  were 
  added 
  

   during 
  the 
  year. 
  It 
  consists 
  of 
  the 
  following 
  collections: 
  Aero- 
  

   nautical, 
  art 
  room, 
  De 
  Peyster, 
  deposited 
  collections, 
  employees' 
  

   library, 
  periodicals 
  (back 
  numbers), 
  reading 
  room, 
  reference 
  room. 
  

  

  The 
  aeronautical 
  collection, 
  founded 
  by 
  Samuel 
  Pierpont 
  Langley 
  

   while 
  Secretary 
  of 
  the 
  Smithsonian 
  Institution, 
  has 
  been 
  since 
  

   augmented 
  by 
  gifts 
  from 
  Alexander 
  Graham 
  Bell, 
  James 
  Means, 
  

   Charles 
  D. 
  Walcott, 
  the 
  Aero 
  Club 
  of 
  America, 
  and 
  other 
  indi- 
  

   viduals 
  and 
  organizations 
  that 
  have 
  had 
  an 
  important 
  part 
  in 
  the 
  

   development 
  of 
  aeronautics 
  during 
  its 
  pioneer 
  stage. 
  During 
  the 
  

   present 
  year 
  some 
  45 
  volumes 
  were 
  added 
  from 
  the 
  estate 
  of 
  James 
  

   Means, 
  by 
  gift 
  of 
  his 
  sons 
  Dr. 
  James 
  H. 
  Means 
  and 
  Philip 
  Ains- 
  

   worth 
  Means. 
  

  

  By 
  the 
  transfer 
  of 
  the 
  employees' 
  library 
  to 
  the 
  east 
  stacks 
  in 
  

   the 
  main 
  hall 
  of 
  the 
  Smithsonian 
  building, 
  it 
  has 
  been 
  rendered 
  more 
  

   readily 
  accessible 
  to 
  employees, 
  and 
  additional 
  space 
  for 
  its 
  ex- 
  

   pansion 
  has 
  been 
  provided. 
  The 
  collection 
  of 
  back 
  numbers 
  of 
  

   periodicals 
  has 
  been 
  moved 
  to 
  the 
  west 
  stacks. 
  

  

  While 
  the 
  office 
  library 
  is 
  primarily 
  a 
  reference 
  library 
  and 
  books 
  

   are 
  more 
  often 
  consulted 
  than 
  borrowed, 
  many 
  of 
  the 
  volumes 
  are 
  

   available 
  for 
  loan 
  purposes, 
  and 
  many 
  employees 
  of 
  the 
  Institution 
  

   avail 
  themselves 
  of 
  its 
  privileges. 
  The 
  total 
  number 
  of 
  loans 
  for 
  

   the 
  year 
  was 
  3,330.
