Inside are about 50 or 60 ziploc bags, each w= ith 20 to 1000 transistors, one part number per bag, and a big label with p= art number and a few specs. Saving space this way wastes a lot of time each= time I need to find a transistor, half the time I don't even know what I h= ave.

Then by type(BJT, JFET, MOSFET), maybe. Grouping co= mplementary types together seems sensible. What next? Usage(RF, switching, = linear)?

This = is just for my corner of the hobby sphere. > > Thanks, Bob I use the multi-drawer parts cabinets with each cabinet labelled with a=20 letter and each drawer labelled with a 3-digit number. For example. A101=20 - A160 in one 60-drawer bin. Then, all parts are listed in a=20 spreadsheet/database containing quantity, part number, supplier part=20 number, supplier name, cost, etc. This way, I don't have to go to the effort of shifting drawers when I=20 add to new part numbers to inventory, and it is easy to look up a part=20 by whatever characteristic you want.
