Did those things have a lot of new information? I've got a recurring search going on eBay, but I'm still not sure if it's worth pulling the trigger on this one.
No "new" information at all really. They still had to follow canonical material. Like the Tech Manuals, some extrapolation and assumed interpretations from episodes was needed to describe the functionality of certain devices. I'm sure tech type people would find plenty of assumptions worth being outraged about.
Sometimes unusual bits would creep in, such as brief information on the Rigellians (sabre-toothed turtles) of ST:TMP, while other TMP and ST IV aliens were ignored. Someone tried to explain the "Yesterday's Enterprise" timeline. The Encyclopedia entries had to restart every so often, as brand new "A" and "B" items became canon.
The "Fact Files" went through several teams of writers over their years of publication, so it resembled other ST fact books' information written by "many hands", rather than just the Okudas.
I do have some of the card format ones, btw.
Well, the style of the writing is similar.
I remember the TNG DVD Collectors' Edition mags cannibalised a lot of the material.
The "Nemesis" DVD magazine, of course, contains all-new material, and was my only must-buy from that last revamp.
the entire 304-issue run (with all folders)
I actually bought five copies of issue #1 (which was deliberately only $2 each, with free binder), and this gave me
four extra free binders, allowing me to space out the sections a little more evenly.
I feel like weeping every time I see the dust-covered set in my bookcase and think of how much money I spent on them.
See, this is what I was saying earlier. Buyer regret. You spent
less than $AU5.00 per week on them and the price never increased, except when our GST kicked in. If
you didn't get $5 of enjoyment out of them, reading, splitting the pages apart, filing, browsing over past entries, etc., then why didn't you stop much earlier?
I certainly got my money's worth, esp. the big weekend marathon of error-correction stickers!
