MD5 of a better version of this file (if applicable). Fill this in if there is another file that closely matches this file (same edition, same file extension if you can find one), which people should use instead of this file. If you know of a better version of this file outside of Anna’s Archive, then please upload it. Please report metadata errors at the source library. If there are multiple source libraries, know that we pull metadata from top to bottom, so the first one might be sufficient. Support authors: If you like this and can afford it, consider buying the original, or supporting the authors directly. A "file MD5" is a hash that gets computed from the file contents, and is reasonably unique based on that content. All shadow libraries that we have indexed on here primarily use MD5s to identify files.
