JOTWELL's legal history section has posted some 
new material: 
Angela Fernandez (University of Toronto) writes about her appreciation for 
Irus Braverman, Zooland: The Institution of Captivity (Stanford University Press, 2012). Here's an excerpt from the beginning of Fernandez's short essay:
Irus Braverman’s recent book Zooland
 is a wonderful read on a topic that is of both historical and current 
interest—zoos. How should we view zoos given the frank admission by all,
 including zoo advocates, that zoo animals are captives, forced to forgo
 what would otherwise be a superior existence in order to serve the 
pedagogical and conservationist agenda that zoos have cultivated as 
justifications for their existence? . . .  
Legal historians will be interested in the shift Braverman describes 
from zoos as sites of entertainment, a variation on the old menagerie 
style collection of animals, preferably exotic, that would then perform 
various colonialist and empire-building functions, to the (arguably) 
more laudable conservationist rationale and its accompanying practices 
often targeted at educating adults and children about species and 
habitat decline and destruction. . . .
