There are a lot of old theology monographs and journals to be found digitized online, but I'm becoming increasingly militant in my commitment to the physical documents and have decided to slowly stockpile an arsenal of texts to fend against any possible disaster that might render digitized representations inaccessible. I strongly support digitizing efforts, but not as a floating currency. I will continue to hoard the paper standard.
So, I bought a few books; nothing amazing, but all in the name of incremental additions to my 19th century German works, which has really become my focus outside of the contemporary literature. I found a pile of Theologische Studien und Kritiken issues from the 1830's, 50's, and 60's in very bad condition, but I've been using the journal a fair amount and thought it would be good to have some of it in print. Included in the pile, I discovered when I came home, were some other items - three issues of Zeitschrift für die gesammte lutherische Theologie und Kirche, with which I wasn't familiar, and a few loose items including a study of Hebrews, and what appears to be the contents of a bishop's personal library (for sale at auction?) and a publisher's newsletter/catalog.
