What is the difference between a scanned PDF and a native PDF?

 
Scanned PDFs vs. Native PDFs
 
 

Scanned PDFs are PDFs that are made up of scanned images of a given document. With scanned PDFs, the user is generally unable to search across the text because the PDF is actually a collection of images. Native PDFs, on the otherhand, are PDFs of documents that were "born" digital - that is, the PDF was created from an original electronic version of a document - a Microsoft Word document, for example. More and more of the content ProQuest includes in our databases is "born" digital, and therefore available as a native PDF when in PDF format (some full text is only available in ASCII/HTML). Each year, the percentage of born digital content added to ProQuest databases increases.
