Does it include all books published in the Meiji period?
This of course is the same question that has always been asked about the Maruzen Meiji Microfilm. The official answer in Maruzen PR was 70 per cent, but there is no indication how they arrived at that number. I suspect that this figure is much too high, if one considers provincial publishers and all sorts of ephemeral publications, but I know of no efforts to arrive at a total number of books published in the Meiji period. (And remember of course no magazines or newspapers are included in the collection: it is only books.
