Many pop­u­lar mag­a­zines are now included in Google books cover-to-cover.  One can search the whole lot, or within indi­vid­ual titles.  Two of the titles which might be of inter­est to read­ers of this news are Pop­u­lar Mechan­ics and Pop­u­lar Sci­ence.  The list­ing by title (cover) is here:

Don’t expect the very lat­est issues!  The inclu­sive dates dif­fer for each title.
