User reviews
My most indispensable extension after my adblocker. Quotidian's Library Extension checks library collections and allows you to choose *which* library collections to check (main aka the physical collection? or electronic collection? both?) and then they provide a link for found items. If you have just one library membership this app is a must - and if you have multiple, well, I don't know how you live without it.
