I don't think those magazine publishers are going to be too happy about someone else offering their old magazines, even if they're not offering them themselves.

I don't think those magazine publishers are going to be too happy about someone else offering their old magazines, even if they're not offering them themselves. Besides, keep it under your hat, archive.org has much more comprehensive collections! In some cases, publishers have accepted that there's a nostalgia-led interest in their old titles, but not to the point that anyone really wants to pay for them, and the titles aren't worth republishing today as their contents are obsolete. As an example of a very nice publisher, Usborne Publishing (RIP Peter Usborne) is still a major publisher in the UK childrens books market, but it freely allows adults to download PDFs of its old books that taught them about computers 40 years ago: https://usborne.com/gb/books/computer-and-coding-books https://usborne.com/gb/books/computer-and-coding-books
