HARVEST Archive Files

These are the scans of the archive files, and the documents they contain, ordered by archive file number. The archive file folder cover contains archival reference data. Concatenating all the files will reconstruct the original archive file.

The files were scanned as grayscale images at 600 dpi to TIFF, with deflate (Zip) compression, then converted to PDF. Thus, the files can be rather large, weighing in at about 4.5MB per page. This was necessary as the originals vary greatly in quality, and often contain fine-line diagrams which would be otherwise lost. Each page is legal-sized to match the photocopies. Most of the documents are letter-sized, however. There is no OCR text processing.

Articles derived from these sources can be found at the HARVEST main page.
