Technical Note

Please note that full-text searching for the electronic-facsimile texts in our collections is based on uncorrected OCR (Optical Character Recognition) results. While such text is often highly accurate, it will contain errors that may affect your search results. In particular, texts with the following characteristics are particularly prone to error (in some cases, accuracy for such texts is so low that we have decided not to attempt to provide full-text searching):

• Hand-written texts;
• Texts that contain diacritics;
• Texts that contain non-Latin scripts;
• Texts that contain obsolete characters (including the "long S" [looks like an "f"]);
• Texts that are printed in a font in which the letters are difficult for the software to differentiate.
