CHAPTER XIV
FOR INSURANCE MEN

For the insurance man, whether veteran or tyro, the new Encyclopaedia Britannica has much of value and importance, and it has it in quickly available form so that the desired information may be readily found, whether the experienced student wants an authoritative statement on a difficult point, or the beginner wishes an outline course of the subject. This availability, whether for the expert or the novice, is secured by the Index (the 29th volume), which guides the reader immediately to desired information, if he does not find it in the alphabetically arranged articles in the body of the book upon first turning up the article in which he expects the subject to be treated.

To be more concrete—if you want to know something about insurance, turn first to the article Insurance in Volume 14, beginning on p. 656. You find an elaborate article, which would occupy about 75 pages if printed in type and on a page like this Guide.

In other encyclopaedias you would have no clue to the whereabouts of any information about insurance except what would be given in the article Insurance or in articles to which it might refer you in that article. For anything else you would have to guess how the editor’s mind had worked to find where in the book he had put other information about insurance; and to guess how each contributor’s mental processes have been related to his interest in insurance so that you might know whether in some article, on a topic apparently not related to insurance at all, the contributor had put in some interesting and important fact about insurance.

But in the Britannica you have one entire volume, the 29th, which was made for the sole purpose of increasing the practical efficiency of the other 28 volumes. Under the heading Insurance in this index, you will find references to many articles and cross references to Title Insurance and to Title Guarantee Companies.

Apart from the fact that he has the initial assurance that what he gets from the Britannica in the first place is fuller and better than he would get from another work of reference, what are the advantages offered by the index in this particular instance?
