Yes, avoid any and all books on the subject of "rune magic", rune associations and rune interpretation. 99% is horse**** made up out of whole cloth by new agers. On the other hand, strictly archeological works are good, as are factual studies on how the runes where used as a writing system.
If you don't know about writing with runes, here's an introduction for the younger futhark:

We don't know anything about the individual runes except some lines of anglosaxon poetry written about them long after they were in use as a magic system, but a take the general meaning of each rune can be revealed there. For ease of perusal, here's the wikipedia list of the runes, click on a rune's article and you'll see the associated poem on the page:
Runes - Wikipedia
Then, read the eddas! It's shock full of instructions
Most importantly is this line in the Vóluspa that tells of the various ways runes can be activated:
"Runes you will find, and readable staves,
Very strong staves,
Very stout staves,
Staves that Bolthor stained,
Made by mighty powers,
Graven by the prophetic God.
For the Gods by Odin, for the Elves by Dain,
By Dvalin, too, for the Dwarves,
By Asvid for the hateful Giants,
And some I carved myself:
Thund, before man was made, scratched them,
Who rose first, fell thereafter.
Know how to cut them,
know how to read them,
Know how to stain them,
know how to prove them,
Know how to evoke them,
know how to score them,
Know how to send them,
know how to send them."
And it is, of course, the last eight lines you'll want to take note of.
From there, it's largely experimentation. I've found using my shamanic and vølve practice helpful: I will use a drum to enter the otherworld, visit the rune in question and communicate with it.
Good wind on your way to work with the runes, and be careful.
