Interesting change for Google here. They've automated an OCR process that coverts scanned images of documents into indexable and searchable text.
In the past, scanned documents were rarely included in search results as we couldn't be sure of their content. We had occasional clues from references to the document-- so you might get a search result with a title but no snippet highlighting your query. Today, that changes. We are now able to perform OCR on any scanned documents that we find stored in Adobe's PDF format.
