Isn’t the iPad (kind of designed for reading magazines digitally) a good option, given the days of print are almost certainly gone or going for everything? They’re also searchable and bookmark-able.
BTW, I downloaded all of the PDFs from a useful resource for getting the back-cats of MacUser (146 editions) and MacWorld (258 editions), available at Vintage Apple.
I also have all PDF issues of Lee Garrett’s (previously started by Don MacAllister!) excellent ScreenCastsOnline magazine edition (~£50/year for the whole service is very fair).
Also know Apple podcaster Stephen Hackett mentioning several times on various podcasts he had a vast DevonThink db of past Apple magazines, can’t remember which ones though. 
Anyone know of any other (preferably downloadable) archives?
(e.g. MacWeek , MacFormat , MacLife , et al.)
Edit 1 - Searching of Archive.org gave some back-cat editions:
MacWeek: https://archive.org/details/macweekmagazine
MacFormat: https://archive.org/search?query=MacFormat
MacLife: https://archive.org/search?query=MacLife
…presume the latter two are likely still under copyright as they still exist even in digital form, hence lack of availability.
Edit 2 - all back-cat editions:
MacAddict: https://archive.org/details/macaddict?&sort=titleSorter&page=2 [pre-MacLife publication]
