I use EXCEl spreadsheet since the nineties. I developed intuitively a field database that in the end was very near to the ARSC system. I use text fields to fill in the information "as it is" and numerical key fields for sorting by dry numbers (catalogue numbers, matrix numbers, control numbers, etc). I register key titles of great works, songs, etc. and artists, and I use always the same spelling, adding between brackets "the real thing" if it's worth (pseudonyms, etc). It is simple, but in the end I have some 30 fields (columns). Now I have almost 10,000 registers (both sides of each 78). Still manageable. And EXCEL filter and sorting tools are great and comfortable to use. Inigo, from Madrid, SPAIN.
