If this is not possible, I would like to request some other way to achieve the same result. Say for example, I have two pgn books. 'Elo_2500_gg', (with all variations for white and for black); and 'Elo_2500_gg_mainlines', (with only the main lines for white and for black). Now I want to create a new pgn book, 'referense_white', to use as reference for my white repertoire. I want the book to include all lines for white from the book 'Elo_2500_gg_mainlines' and all lines for black from the book 'Elo_2500_gg'. I only want white reply’s from the book 'Elo_2500_gg' to be included in the book 'referense_white' if there is no white reply already included in the book 'Elo_2500_gg_mainlines', transpositions included.
It is impossible since PGN books lost all information about sides, scores/weight... Just take a look into a PGN book, you may see each opening line is simply a list of moves without any extra information.

If there was an efficient way to convert bin books to pgn, I could already do this by using the book merging options of bin books. Maybe there is already some method to achieve this? With pgn-extract or maybe some others software.
A binary book such as Polyglot can provide more information such as weight for each move. That is much better for merging and converting to PGN/EDP books.
I will add more tools/functions later (such as converting from Polyglot to PGN one).
I really like the idea of a tool to convert polyglot books to pgn. Polyglot-Tolerant
https://chess.massimilianogoi.com/downl ... ttolerant/, has an option to convert a bin book to pgn. It is very fast but also very inaccurate. A lot of threefold repetitions are included, that where not in the original pgn files, (like knight and bishops getting back to there starting positions, rooks moving back and forward, ect). Also if I convert a merged book to pgn with Polyglot-Tolerant a lot of lines are missing in the pgn file.
Lucas Monge, the programmer of Lucas Chess, send me two converters to convert polyglot books to pgn. An accurate one and a fast one. The accurate one is very, very, very slow, and the fast one does not include al variation in the pgn file if trying to convert a merged book. I will send you a copy of the converters in a PM.

That is all I need, a list of moves. If I want to find the original games, I can do it as described in this post:

It gives probably problems with transpositions. In SCID you can load a pgn database as a tree and see the statics. You cannot see moves that transposes, (like the option in Chessbase for ctg trees), but if you make a move on the board that transposes, you can see the continuations, (unlike navigating an obk book in Chessmaster 9000).
