Body: <p>I understand the Polyglot opening format is open source, but I can't find available opening books for polyglot. I'm looking to use a book to automatically identify (and exclude) opening moves from a program to analyze large numbers of PGN files.<br />
  Is there a reliable place existing (open-source) polyglot books are available?</p>

  I understand the Polyglot opening format is open source, but I can't find available opening books for polyglot. I'm looking to use a book to automatically identify (and exclude) opening moves from a program to analyze large numbers of PGN files.  
  Is there a reliable place existing (open-source) polyglot books are available?

  I found two sources for Polyglot opening books:
  
  1. Richard Pijl has released [his opening book](https://maughancdn.s3.amazonaws.com/chess/The%20Baron/baronbook30.zip) alongside *The Baron 3.43*, which he says is almost identical to the version that played in the 2018 WCCC. Read more about these [here](https://www.chessprogramming.net/new-version-of-the-baron-v3-43-plus-the-barons-polyglot-opening-book/).
  2. Sourceforge claims to have a polyglot book collection for download [here](https://sourceforge.net/projects/codekiddy-chess/files/Books/Polyglot%20books/Update1/polyglot-collection.7z/download). The main page is [here](https://sourceforge.net/projects/codekiddy-chess/files/Books/Polyglot%20books/Update1/).
  
  EDIT: Found two more [here](https://digilander.libero.it/taioscacchi/programmi/saros-page.html).
