4,542; reprints, 1,129; a tota ^ °* 11,687 copies, or 2,665 more 

 than in 1919. Part of the large sale of publications is due to 

 the fact that the Guide was kept more continuously in print 

 than ever before, but an offset to this is found in the fact that, 

 on account of the amount of printing on hand, it was not pos- 

 sible to keep the Leaflets and Handbooks as constantly in print 

 as the Guide; otherwise the sales would probably have been 

 greater than they were. 



The work of the printing office has been, as usual, large and 



varied. Its efficiency has been increased to some extent by the 



addition of a second monotype casting machine, 



Printing an( j mucn more by the transfer of the printing 



office to the basement, thus bringing together the 



entire force and equipment. 



That more labels have not been printed is due to the fact 

 that so many have been provided in the past few years that we 

 are beginning to catch up, though it is safe to say that no 

 museum is ever completely labeled. 



Another step which has added greatly to the ability of the 

 Museum to handle its publications promptly and efficiently has 

 been the addition of folding and stitching machines to the 

 bindery — under the charge of the librarian ; but, since no addi- 

 tion was made to the bindery force, the amount of work turned 

 out for the library of necessity has been lessened.
