Instructions stay within the boxes or bags of the set (bags in case I do not have the box anymore).
Reason is to keep the set complete (including the instruction) and in case I want to play with the set and setup the content (especially complex building sets) I have the instruction right handy with the set itself. -- So with this no need for me to find a solution organising the paperwork.
For "organising" the instructions I also use the computer: I scan them into one PDF document each single instruction so I can look up items when I'm at the computer (what is quite often ... being at the computer, not looking up
).
The PDF documents are names with the set number and the ordering number of the instruction itself, e.g.
3068 - 30892100-pdf. They are all located in one directory for easy access.
Additionally I have setup my local copy of my collection HTML-page from
my homepage in that way, that when clicking on the instruction symbol the PDF document will be opened directly within a browser window; most times this is faster than navigating to the instructions folder.
