This thread is for showing others what's on your bookshelf and book reviews! I'll start with my current nature related shelf. I haven't read some of these in a while so no reviews until I reread them. I have lots more online books (particularly more expensive books), I obtain through unscrupulous means (I gotta read somehow!).
My birding shelf. I like the "Atlas Of Extinct Animals" because every time I read it I'm reminded by how many animals we humans have wiped out.
My botany shelf. I particularly enjoy the books by RedFern. They do very cool expedition opportunities to places to see rare carnivorous plants like Heliamphora and Nepenthes. A bit too expensive and time consuming for me at the moment sadly. Maybe I'll jump on their offerings for 2028-29.
My marine life shelf. I'm really into reef systems.
And finally my Mycology and feeble insect book collection (most of my ant books are online).
