by year in marked 3 ring binders. you can buy plastic seperators that go in the binders then slip your magazines into them. i put the name of the company on a label and attach to spine of binder.(mccalls, fons and porter, etc).and the dates, (1997 to 2000, for instance). i find this is very organized and convenient as i have them on a shelf and can find at a glance what i am looking for.
