Just wondering how most bands operate the music library and how do you allocate new music to the library? Some years ago the KSB library was kept by "category" and then allocated a code and number e.g. Marches (A) A1 - BB&CF, A2 - Castel Coch, A3 - ORB, Test Pieces, Overtures etc would then be allocated the same way. As new pieces were added they would get the last number in the sequence which of course would then mean it wasn't in an alpabetical order. Disadvantages with this system would be how to categorise the music - e.g. items that for example have been a show and a film. The library was re-filed some years ago on a purely alphabetical order A1,A2,A3....B1, B2, B3 etc and a separate spreadsheet is kept with additional information about type and where a piece can be allocated to one or more themes it is identified. Disadvantage with this system is that as new music is added it gets the last number so we might have 50 pieces begining with "A" that are filed alphabetically but then the last 4 pieces will not be in alphabetical order. So what's the best way? I was considering scrapping the numbers and codes altogether and simply filing the music in alphabetical order - I've got all the details on a spreadsheet which is easy to adjust and search for information. But most bands libraries that I've seen always seem to have a number on the music too - can anyone suggest why? I suppose if you have a sequential set of numbers you can see if something is missing, which is not so easy with just the alphabet by title.
