Abstract

A system for indexing releasably bound numerically categorized textual material provides a high degree of convenience. A plurality of dividers is provided each of which corresponds to and separates alpha numerical categories and each divider has a tab associated therewith. Each tab includes means for displaying indicia which include at least the last digit of the respective alpha numerical category. The releasably bound assembly of textual material has an edge-face portion which is divided into a number of fields equal to the number of possible last character of alpha numerical categories. Each field corresponds to the last character of a numerical category and contains a bank of tabs arranged sequentially in superposed relationship. Each tab in a respective bank of tabs has the same last character, e.g., digit. The system provides for frequent revision, such as removal of some categories and addition of other categories along with the respective dividers and associated tabs while maintaining the same high degree of order and convenience, even after extensive revision.

  1. 1. A system for indexing an assembly of releasably bound textual material divided into categories and subcategories, the assembly including a top face, bottom face and a side edge face which is defined by a top edge and a bottom edge and extends from an upper corner to a lower corner of the side edge face, the system comprising:indicia associated with each category and subcategory for titling the categories and subcategories with a categorical number and a field number, wherein the field number includes at least one digit which is "0" or an integer in the range of "1" to "9", the field number being the last number associated with the category or subcategory;category and subcategory dividers, all being substantially the same width and length, each of which corresponds to and marks the beginning or end of a category or a subcategory;single primary tabs each attached to a category divider at the beginning of a category, each primary tab displaying to least the last digit of the respective category so as to provide a field number, each primary tab having a selected area and projecting from the side edge face of the assembly when the assembly is closed so as to be visible when the assembly is closed;single secondary tabs attached to each subcategory divider at the beginning of a subcategory, each secondary tab displaying at least the last digit of a field number and having a selected area substantially less than that of a primary tab and each secondary tab projecting beyond the side edge face of the assembly when the assembly is closed so as to be visible when the assembly is closed;wherein the length of the edge-face portion is divided into ten non-overlapping fields equal to the number of possible digits, and each field corresponds in a one-to-one correspondence to one of said digits;wherein each tab is located in the field which corresponds to its last digit;wherein at least one field contains a plurality of category and subcategory tabs, and all fields containing a plurality of said tabs have said tabs arranged sequentially is superposed relationship, andwherein the numbers on the tabs in each field are arranged in ascending order beginning from the top face of the assembly and moving toward the bottom face of the assembly;whereby the total number of tabs between the first tab in the first field and last tab in the last field is not limited by the number of categories in the system, allowing the system to easily expand and contract as categories and subcategories are added and deleted, thus providing a flexible system which maintains its convenience over time.
  2. 4.4. A system for indexing government regulations or statutes arranged in an assembly of releasably bound textual material divided into categories and subcategories, the assembly including a top face, bottom face and a side edge face which is defined by a top edge and a bottom edge and extends from an upper corner to a lower corner of the side edge face, the system comprising:indicia associated with each category and subcategory for titling the categories and subcategories with a categorical number and a field number, wherein the field number includes at least one digit which is "0" or an integer in the range of "1" to "9", the field number being the last number associated with the category or subcategory; the field numbers being organized with the digit "0" positioned after the digit "9" so that the digit "0" represents the number "10", thereby providing a number field for numbers which are a multiple of the number "10"; the field numbers being arranged to start from the upper corner of the side edge face of the assembly and ascending toward the lower corner of the side edge face of the assembly;category and subcategory divides, all being substantially the same width and length, each of which corresponds to and marks the beginning or end of a category or a subcategory;single primary tabs each attached to a category divider at the beginning of a category, each primary tab displaying at least the last digit of the respective category so as to provide a field number, each primary tab having a selected area and projecting from the side edge face of the assembly when the assembly is closed so as to be visible when the assembly is closed;single secondary tabs attached to each subcategory divider at the beginning of a subcategory, each secondary tab displaying at least the last digit of a field number and having a selected area substantially less than that of a primary tab and each secondary tab projecting beyond the side edge face of the assembly when the assembly is closed so as to be visible when the assembly is closed;wherein the length of the edge-face portion is divided into ten non-overlapping fields equal to the number of possible digits, and each field corresponds in a one-to-one correspondence to one of said digits;wherein each tab is located in the field which corresponds to its last digit;wherein at least one field contains a plurality of category and subcategory tabs, and all fields containing a plurality of said tabs have said tabs arranged sequentially is superposed relationship, andwherein the numbers on the tabs in each field are arranged in ascending order beginning from the top face of the assembly and moving toward the bottom face of the assembly;whereby the total number of tabs between the first tab in the first field and last tab in the last field is not limited by the number of categories in the system, allowing the system to easily expand and contract as categories and subcategories are added and deleted, thus providing a flexible system which maintains its convenience over time.
