of books of first importance for local and general geologic 

 information is therefore an exceedingly difficult task, which 

 is attempted with some misgivings and it is hoped that the 

 effort will be accepted in good part by the public. 



In preparing the list here compiled an effort is made to make 

 it suited for use in public schools and small libraries. In fact, 

 the number is so limited that it can well be accommodated 

 in the private library. The need of keeping the list from 

 attaining unwieldy dimensions prevents the mention of dozens 

 of books, many of which are of equal merit with the State and 

 Federal Survey publications that are mentioned. Persons 

 wishing more ample information concerning books on special 

 subjects will be given earnest attention on application to either 

 the State or Federal Geological Surveys. Only a few of the 

 numerous excellent modern books on geology can be mentioned 

 here and an effort is made to hold strictly to elementary treatises. 

 More ample lists are given in the recent announcements of the 

 American Library Association. There are a number of geologic- 

 magazines which furnish channels for prompt publication of 

 investigations of general interest, and in fact there is muchi 

 information of prime importance which is printed only in such 

 magazines. Some of the more important ones are given in 

 the lists that follow. 



The material suggested for the geological library falls in 

 two classes: (1) Text books and other books of interest as a. 

 general source of geologic information and educational value;. 

 (2) Reports concerning the geology of specific areas including 

 the most important State and Federal Survey publications and 

 also geologic and topographic maps. The first class is useful 

 no matter in what part of America the reader lives. The second 

 class must necessarily consist of many lists, each of which will 

 be appropriate for a State or, where the interests are varied, 

 for part of a State. 



The following lists include, in addition to text books and 

 books of general interest,, the more important publications of 

 interest to people living in Ohio. 



Class I. Consisting of text books, periodicals and pub- 

 lications of the U. S. Geological Surve}^ and Bureau of Alines of 

 general educational value and interest.
