Abstract: An index tab for a file folder includes an integral base member adapted to be affixed to the file folder. The base member includes a relatively flat base portion engageable with a surface of the file folder, the base portion having a pair of opposed strip engageable notches at opposite edges of the member. The base portion further includes at least one ear means bent about the base portion and engageable with an opposite surface of the file folder. A rotatable strip of flexible material circumscribes the base portion and engages within the opposed strip engageable notches. The strip carries a series of indentifying indicia. The ear means, in one version, can be bent about a fixed axis and a point on the strip is rotatable within a plane which is perpendicular to the fixed axis. In another version, a point on the strip is rotatable within a plane which is parallel to the fixed axis.The rotatable strip can include alphanumeric indicia such as numerals, months, years, dates, and color.
