treasure-trove. What are the best and most interesting
of public-facing (by design or by oversight) public-domain archival materials? How does one find more of them?
My chief interest with this question is finding open directories of large, archival-quality historical maps (such as this one
from U of Wisconsin-Milwaukee
); but I'm always excited when I come across fantastic directories of other materials (images/pdfs/shapefiles) as well.
is a good resource, but it's a little too warez/porn heavy, and my only interest is in public domain archival materials.
How does one find these? I've had luck with just finding where the image lives, and then looking for an "index.html"
. Otherwise, I've had mixed results by kludging together some tailored google searches, such as:
...but I'm sure that these can be improved upon. I arrived at them by trial-and-error and it's frustrating to try to discern the efficacy of minor changes to the formula.
Common file types I am looking for are MrSID [.sid]; JPEG 2000 [.jp2, .j2k, .jpf, .jpx, .jpm, .mj2]; TIFF [.tif, .tiff]; and to a much lesser extent Deja Vu [.djvu, .djv]. Though if you know of any other types associate with large images, I'd welcome the input.
Feel free to MeMail me if you don't want to post publically. I will respect your wishes regarding non-/disclosure of whichever resource.
