TITLE: Where can I find online copies of class field theory publications by Kronecker, Weber, Chevalley, Hasse, Hilbert, Takagi, etc?
QUESTION [9 upvotes]: I am writing an undergraduate thesis on local and global class field theory from a classical (i.e., non-cohomological) approach and am hoping to obtain copies of the early groundbreaking publications in the field. I am primarily interested in finding English translations of  articles from Weber, Hasse, Hilbert, Kronecker, and Takagi from 1850 to around 1935 as possible. A fairly comprehensive list of them is found in Hasse's "History of Class Field Theory" in Cassels & Frohlich's ANT, and I can provide a list if needed. Any recommendations for sites that provide translated back issues of Mathematische Annalen and/or Gottinger Nachrichten from these time periods would be of great utility.
Edit:
Thank you all for responding! You're answers will definitely help me develop the historical portion of my thesis. In response to several comments, I realized when posting that it was probably naive to assume that English translations of all these works were available but presented the question in the above manner for the sake of brevity.
@KConrad:
I actually found your cfthistory.pdf file while googling the subject early in my research and have benefited from it greatly! Small world! :)
I would be fine with library copies of the works, of course, but my university would have to order copies from other institutions. As such, I thought I'd first make sure there wasn't some large repository of translated articles from Hilbert et al. online somewhere.
I can't thank you enough for this list of sources, too! I will definitely attempt to get my hands on as many as possible.
Thanks again for helping and posting your history of CFT online!
@Ben Lenowitz:
Thank you for pointing me to the Gottingen database. I haven't been in awhile and not while searching for these articles. I will give it a shot.

REPLY [4 votes]: Recently I found that some of Takagi articles were published in a Botany journal (?!) called "The journal of the College of Science, Imperial University of Tokyo, Japan".
Iyanaga, in his "The Theory of Numbers", cites three articles by Takagi published in this journal: 
[1] Über die im Bereiche der rationalen komplexen Zahlen Abelscher Zahlkörper, J. Coll. Sci. Tokyo 19 (1903), Article 5, 1-42.
[2] Über eine Theorie des relativ-Abelschen Zahlkörpers, J. Coll. Sci. Tokyo 41 (1920), Article 9, 1-133.
[3] Über das Reziprozitätsgesetz in einem beliebigen algebraischen Zahlkörper, J. Coll. Sci. Tokyo 44 (1922), Article 5, 1-50.
All three of them are available in the links above.
Actually, there are some nice illustrations in the Botany articles :)
