Update:
Since last update, When I try to open Internet Archive catalog, I get "Catalog error. Cannot connect to online catalog." I can download books directly on Internet Archives webpage, though, so I can connect to their online catalog. The app just cannot. No problem with other in-app catalogs, so it must be a glitch. Please fix!
Best ereader app. Great customer support, too.
