The problem with those home encyclopedias was they were mostly a decade or more out of date. And only provided a very limited amount of information. Generally only a few paragraphs or a page at best. Reference books suffered the same problems of not being current. Turns out books cost money and knowledge ain’t cheap.
The only reference book that I own that is even remotely up to date is the last Machinery’s Handbook I bought. And even that is multiple issues behind now.
They still do. Birthdays and funerals are also fodder for small town print papers.
