Hi LibriVox,
In https://librivox.org/the-hunting-of-the-snark-by-lewis-carroll-3/ one can download https://archive.org/download/huntingofthesnark_1603_librivox/hunting_snark_1606.pdf
There you write: "Cover picture by Henry Holiday. Copyright expired in U.S., Canada,
EU. and all countries with author’s life +70 yrs laws. Cover design
by Annise. This design is in the public domain"
That is wrong. The correct text should be: "The cover picture is a collage by Goetz Kluge (2012) from images by Henry Holiday (1876, engraver: Joseph Swain) and Thomas Landseer (1838, based on a painting by Conrad Martens, 1834). Copyright expired in U.S., Canada, EU. and all countries with author’s life +70 yrs laws. Cover design by Annise. This design is in the public domain"

I know that you work with volunteers and that you don't use my collage for profit. So it's fine with me to have that cover in public domain. But all contributors should be mentioned.
Best regards,
Goetz
