Japaneses Transistor Manuals

In the late 90's there were a variety of Japanese semiconductor manuals. In the lineup was a substitution manual. MCM used to sell them. I checked Parts Express and they only have speaker books. Where can I find the Transistor Substitution manual? Below is what I have.

Somewhere on these boards, a long time ago, someone posted PDF's containing Japanese transistor substitutions. I think there were four PDF's in total, not sure. I do remember downloading them but where they are in my files, I'm not sure. Doing a search here might bring them up.
 
Probably not a whole lot of use since even the subs they would call out are obsolete. ECG manuals were not very good either, some called them the book of lies. ECG datasheets were lacking a lot of info. Many of the Japanese device data sheets are available except I can’t find ones for mfr like Mitsubishi. Lots of older device data sheets are written in Japanese. Once you have device data sheets then you have data in order to find a sub if it’s possible from what is being made today.
 
Way back when, before the internet...

Companies had actual libraries and in those libraries you often found shelves full of electronics manufacturer's books listing components and datasheets.

I imagine they were all recycled by the ton. I remember cleaning out a "library" at one place I worked at in AZ. I reclaimed a couple of text books but all the manufacturer data books got recycled.

Finding something like that nowadays is like treasure hunting.
 
I got mine (4-6 of them) from eBay... but they were very, very hard to find there.

Lately I did see a little "lot of databooks" for next to nothing (compared to the past...) on the internet market, but there were no bids.
