ABSTRACT:
An improved dictionary index that allows a person to open a dictionary often just a few pages from where his word is located. Given the word "ran," r, a, and n are #1, #2, and #3 letters respectively. This index allows a person to open to where the #2 letter begins, and if set up for it, in many cases to open to where the #3 letter begins, so that in this case the person is shown where to open the dictionary to have "ran" on that open page. This is accomplished partly by subdividing the words beginning with #1 letters into lesser categories--26 if each of the letters is to be presented as a #2 letter, and perhaps 40 or more if some #2 letters are further subdivided into #3 letters--for instance such #2 letters as A, E, I, O, U, H, L, N, R. A chart of these perhaps 40 letters is placed for instance on the inside back book cover where the cover extends past the pages. Within the successive pages in the dictionary that are provided for the words of each #1 letter (presuming for the moment that each of the 26 #1 letters' pages are to be dealt with), on the page of any particular #1 letter where each of these 40 categories is earliest found, a mark is printed on that page edge directly across from the category on the chart. The first of these 40 marks, being that they are arranged alphabetically, begins on an earlier page in the dictionary at the top of the dictionary. The last of these 40 marks is at the bottom of the dictionary some pages back at the end of this particular #1 letter, with the in-between 38 other marks arranged between, so that there appears to be a "diagonal line" of marks reaching across the page edges of this particular #1 letter. In same manner make a diagonal line of marks for the pages of each of the other 25 #1 letters. Herein the same categories on the chart are used for each of the #1 letters, so that finally there are 26 separate diagonal lines, and across from each category there are a total of twenty-six marks. With such a manufactured dictionary index, by a person locating his #1 letter's diagonal line and finding his #2 and possibly #3 letter on the chart, he can quickly find where in the dictionary his #2 and possibly #3 letters are located by reaching to the mark across from his category on his #1 letter's diagonal line and opening the dictionary to that point.
