PUBLICATIONS 



The issue of a series of publications was begun 

 early in the history of Field Museum of Natural His- 

 tory. These have been published in the following 

 series: Report, Anthropological, Botanical, Geological, 

 Ornithological and Zoological. More than two hundred 

 have been published up to the present. Among them 

 are excellent treatises and monographs, as well as nu- 

 merous reports of discoveries of scientific interest. 

 These publications have a wide circulation among 

 other museums, scientific societies and educational 

 institutions, with which an exchange system has been 

 established. A list of the publications may be had on 

 application to the Director. 



Lately a series of illustrated leaflets of a popular 

 type has been started. These treat of interesting ex- 

 hibits, some of them being economic in character. 



Since its removal into the new building, the Museum 

 has installed presses and now does its own printing, 

 and photogravure work.

 world is a vast treasure-house filled with an inexhaust- 

 ible store of riches, which await the arrival of the 

 trained investigator who alone is able to recognize 

 the value of these gems in the rough. All great mu- 

 seums have expeditions in the field, searching dili- 

 gently for treasures of various kinds. Field Museum 

 of Natural History holds a proud record for field inves- 

 tigations during its short history. It has extended its 

 expeditions, like tentacles, to practically all parts of
