Probably not--I'd keep them if I had them on my shelf.

The ones I have from the same time frame are still on my shelf. Not, notably, in the garage.
If you never repair your own printed circuit boards you may consider finding a home for them. They're not trash.

so these coul aid me in some ways when it comes to repairng a heathkit? or osborn?

I see several books there, with the top two being for diodes and SCRs. What are the remainder?
I like to use paper books when working on things. Almost certainly, this stuff is available online, but is not nearly as convenient for bench use.

I've so often looked for an obsolete component online & not found it. Old data/equivalents books are worth hanging on to.

Yes, these are useful in board-level repairs of Osbornes & Heathkits.
If you've got a bad part, you can look up its specifications and select a substitute part if the original isn't available.
Or, when troubleshooting, you can find out what a part should be doing and compare that to how it looks in circuit.
At a simpler level, you can look up exactly what it is and what type of package its in to help you order another one just like it. For example, if you have to replace a power supply transistor, you call up the parts house and say, "I want a TIP-35C transistor." Then they say, "You want TO-3 or TO-218?" You can look up your part in the book ahead of time and know which it is.

Sweet!
That's a great set of basic references for older computer hardware. The time frame is right, too. Late enough to have some of the 16 bit devices in, but not so late that the significant early 8-bit devices have been pushed out.
