Looking for an old "world fashion/clothing" book...

[littlestclouds]

I've been trying to remember the title of this old book but I can't think of it, for the life of me. It had illustrations of clothing/accessories/etc. from ancient dress (the illustrations of Egyptian fashion were done to resemble hieroglyphics) up to the "current" time period of the latest edition I remember reading (I want to say at least the '50s, possibly '60s-'70s and it may have been updated since). I've looked on Amazon but none of the books I looked at quite ping my memory. It might have had "encyclopedia" somewhere in the title.

Dolphin intelligence experiment

[tsukishima_shizuku]

I read this book in elementary school in the mid-90s in USA and I believe it was fairly newly published at the time. It was a middle-grade chapter book with a blue cover.

I don't remember a lot about it but parts of it were told from the point of view of a dolphin (or some type of cetacean) undergoing intelligence testing. Then at some point the dolphin might have escaped from captivity. That's all I remember...
