1 - Realize that you have an old LP, 45 or audio cassette that you miss hearing because maybe you have no turntable or cassette player or you just want them preserved on a CD.
2 - If it is a commercial recording, check online or at your local music store to see if it has rereleased on CD and available and if so purchase it there as your record or tape probably has scratches or tape is not the original quality.
3 - If #2 above is not feasible, or it is a unique recording such as your cousins band did an album or you have a tape of yourself or friends or maybe you have tapes of your great grandmother telling of old family history then go to step #4.
4 - Deliver albums or tapes to me with any info as far as titles that may not be evident.
