Physical text compression

I have accumulated a large number of books in the past two or three centuries, including a rather useful copy of the Book Of Abrelim The Mage. Anyway, as time goes by, the volume of volumes grows while that of our dwelling remains similar. A sufficiently high value to the cosmological constant might remedy this issue, but so far, no dice. I suspect this matter is a common concern.

Therefore, methinks there's a gap in the market for a service which takes one's tomes and renders them into more compact forms, though appropriate for the vintage of the works themselves, thus: the oldest books are copied by scribes into forms using Black Letter and mediaeval palaeographical abbreviations, those of greater intermediate age into Elizabethan handwriting form (which is, incidentally, my own handwriting), those of lesser intermediate age are similarly transcribed into Pitman Script (shorthand is useless for this as it's double-spaced and in any case quite expansive compared to ordinary text) and the newest into printed txt spk. Then, the margins and font size of printed books are somewhat reduced and related volumes are bound together (e.g. Encyclopaedia Britannica has, say, a dozen books rather than more than two dozen) and the paper and ink of the originals are recycled into the paper and ink comprising the new versions, but on thin, Bible-type paper. Maybe also make each page slightly taller or wider, customised for the shape and size of the bookshelves. Photographic reduction a la microfiche, only not so small, more like the reduced version of the OED which comes with a magnifying glass, is also available for works of the appropriate era. Even microfiche itself might be apt for books of the mid-twentieth century when that was seen as the wave of the future.

Your library is then returned to you in a smaller physical form, perhaps with the option of a number of blank notebooks and inkhorns made from the ink and paper saved, though clearly this would be problematic from the space-saving perspective, thereby freeing up one's shelves for further codical influx.
