I've used some lick books over the years, but I don't think any of it ever crept into my playing.
On the other hand ...
One of my teachers, Steve Erquiaga, had me write out licks. I think there were some rules (this was quite a few years ago, so I don't recall it clearly), mainly that the downbeats had to be in the chord or scale and the upbeats could be anything. Or something like that.
Anyway, I wrote out a handful of them one week. I still use one of them.
I also use a couple of licks I learned from teachers. And a few from records.
But, for some reason, I don't think I use any lick I ever learned from a book.
Anyway, the point is that I've spent lots of time with things that didn't seem to get into my playing and reading licks out of books is one them. Maybe if my memory was better, I'd have gotten more out of that sort of thing.
If I had to recommend a book anyway, I think it would be one of Lenny Niehaus'. Not a guitarist tho.
