— Many  scientists  lack  the  library  facilities  which  their  work  de- 
mands. They  are  compelled  either  to  journey  to  distant  libraries  or 
to  try  to  borrow  books  by  mail.  Often  it  is  difficult  for  them  to  lo- 
cate some  thing  that  is  badly  needed,  and  again  it  may  be  impossible 
to  borrow  it. 
The  Research  Information  Service  of  the  National  Research 
Council  is  prepared  to  assist  investigators  by  locating  scientific  pub- 
lications which  are  not  generally  or  readily  accessible.  It  will  also, 
as  is  desired,  have  manuscripts,  printed  matter  or  illustrations  copied 
by  photostat  or  typewriter.  The  cost  of  copying  varies  from  ten  to 
twenty-five  cents  per  page.  No  charge  is  made  for  this  service  un- 
less an  advance  estimate  of  cost  has  been  submitted  and  approved 
by  correspondent. 
Requests  for  assistance  should  be  addressed,  National  Research 
Council,  Information  Service,  1701  Massachusetts  Avenue,  Wash- 
ington, D.  C.
