 Despite that, Miller found it interesting that public domain titles had functionality to view them either as a "scanned version - with the original type, page numbering and even library stamps and marginalia, basically photographs of the printed pages" and also as "searchable "flowing text," rendered by optical character recognition".Miller also wrote that the eBookstore was not easy to search, "an irony considering that the Google empire was built on search".She criticized the user interface for being "poor" and seemingly "devised by people who know next to nothing about the book trade".
