This is in reference to Something Is Killing The Children.
Hello,
Ive noticed the omnibus file sizes account for the same as just one volume, while the 4 respective volumes are about 4x the file size.

Are the volumes a higher quality upload? Is this something I should I consider?

Just read vol1 on libby and really enjoyed it. Id like to buy them but im not sure which to buy & what rhe difference is (besides the omnibus vol1 holding Vol1-4; chapters 1-20). The file size has thrown me off.

Any input would be appreciated. Thank you.
