Starting Out v. Move by Move
If you have the time and energy, my guess is that Lakdawala is the way to go. As I mentioned, he has something of a repertoire-for-White attitude, leaving out some possible White choices in order to provide more help on others. However, at times, he does make some attempt to give the reader more than one choice.

Actually, the Amazon description states that a Slav repertoire for Black is given by Lakdawala. Highly rated book.
When you face one of those quandries that one sometimes encounters, you can ask yourself, "What would Vigus do?"

Of course, HoneyBadgerOz is has emphasized the intros and explanations of Sadler (possibbly outdated but for my level probably won't matter) and Vigus...I'll see if I get any more input...then make a decision...
I should have the link to the review of Lakdawala, tomorrow. I think I can find a Vigus review, too.

I like Kasparov's books. Although I understand very little of what he's saying, they look great on my shelf.

He probably doesn't understand the Slav. Sometimes he misses a move, six moves ahead. His IQ is only 190.

What is that photo all about? He is into fist fights? Looks like he should stick with chess and not boxing.

I respectfully disagree, chess-boxing is great fun!

ROFL. Maybe Lakawakachewbacha he just wanted to write an extraneous 200 pages. That guy is off the list. I don't have time for that drivel.
I find Reuben Fine to be a good writer...
I'll add Sadler to the list. Good suggestions. Will start with Vigus most likely...and, of course, Robert's Slav blogs (instilled with sardonic and impetuous temerity).
Fine is quite a bit outdated, writing in the 1940's.
Vigus is good. Flear would be even better.
Get both.

If I remember correctly, the Lakdawala book got a good review. I'll try to post a link tomorrow. For now, I'll just make some obvious points. (I am not really qualified to make any other kind.) The Lakdawala book is over 400 pages and does not cover the Semi-Slav. About half of the (much shorter) Flear book is for the Semi-Slav. In addition to covering more Slav possibilities, Lakdawala made some attempt to discuss how a Slav-player could adapt it for play against flank stuff. Also, Lakdawala's book is more recent. Flear comes closer to providing a quick Slav introduction. Vigus has more emphasis on lots of lines and less emphasis on explanation, compared to Lakdawala and Flear. Sadler is kind of like an older Flear. Last century if I remember correctly, but Sadler was a really big name in chess in those days. He covered the Slav and Semi-Slav in separate books. Lakdawala and Vigus had more of a repertoire-for-White approach than Flear and Sadler.
Flear's book is much shorter, but 200 pages of Lakdawala is the meaningless drivel I posted on page 1.
