How can I read an Chess Informant Monograph I have a paperback version of A65 The Benoni by Chess Informant. This is my first monograph ever, and I cannot understand how to read it. Any ways to do it? Searching didn't help at all.
In the very first pages of the book you will find code system. It is described in 5 world languages and Serbian. 

This is important to know so you can see at the end of the line what is the final evaluation of the position, if there are any novelties or alternative moves and so on.

Then you can skip the pages all the way to the line you wish to investigate.

Main line is written in bold font and the subvariations are given in normal font. This is the important part, and probably the one that confuses you:

If you see a number next to the move, something like ♘f319 this means that there are alternative moves. You can find them by searching for that number ( in our case 19 ) in the section that comes after the main lines end. 

Below is the picture of what I am talking about:



You seek the number next to the move in the section marked with an arrow, at the bottom of the picture. Instead of playing ♘f3, from our example above, you play the move from that section. 

That's it! If you have further questions leave me a comment ( for now there is nothing else I can do to help because your question is not specific enough ).

Hope this helps, good luck!
