A method of associating first media with at least second media is described where the first media comprises encoded first auxiliary information. The first auxiliary information is auxiliary to the first media. The method includes receiving electronic data representing at least a portion of the first media, the electronic data being obtained from a portable storage device; decoding the encoded first auxiliary information from the electronic data to obtain the first auxiliary information; providing second auxiliary information, wherein the second auxiliary information is based on the first auxiliary information and is auxiliary to the second media; and encoding the second auxiliary information in the second media by altering data representing the second media to yield encoded second media, wherein the second media comprises an electronic form, storing the encoded second media in a storage device in a handheld device.
