ABSTRACT:
A tabular indexing system is provided having index insert sheets incorporating perforations defining a plurality of index tabs, so that unused index tabs may be removed from the insert sheets, and protective carries into which the index sheets are inserted. The index insert sheets are preferably the size of a full sheet of paper and may be used in photocopiers for making multiple sets of indexes. Index insert sheets having pre-formed, die-cut tabs also may be used. The protective carriers are suitable for use in loose-leaf binders or the like. The index insert sheets may be provided with perforations defining semicircular tabs that may be opened and used for holding additional sheets of paper on the insert to prevent the index tab from being covered.
