Abstract Record cards including film jackets and/or film record cards may be readily and conveniently indexed for filing and retrieval by applying a coded pressure sensitive tape at an edge of the record card after the record card has been dated or up-dated. Advantageously the pressure sensitive tape may be applied along an edge or a portion of an edge of the card with the length and location of the tape serving an indexing function. The tape is preprinted with striping or other indicia and is color coded. Application of the tape to only a portion of the edge allows the use of the edge for additional means of indexing such as notching. In addition, the tapes may be superimposed on each other. Where the film jacket is transparent the pressure sensitive material may be a transparent material bearing printed matter which printed matter will be reproduced with the microfilm in the jacket.
