Quite simply DATABASE SOFTWARE, wether it be Access on PC or FileMaker Pro on MAC, we register every tape as a R0000 number on entering the building. This number is kept all the time, when somebody has time i.e. runner…he LOGS the tape into sections…i.e. windfarm…..car ride….bus ride……etc.When the program is finished, it becomes a MASTER thus earning a M0000 number and a seperate database is the set up for MASTERS.
then just do a search for material required.
