Information about these volumes

For the first time in the history of the Bach Society with these volumes
the complete "Ancient Publications by Bach" appear in a digitalized form.

The edition of Leipzig Municipal Library has suffered a lot in the course
of time since 1851. Bindings have been broken and the condition of the paper
has become ruptured and cannot be used for everyday's practical work anymore.
Even more: due to water spots the diagonals have been moved out of place.

Because of the steotype printing of those times you cannot be offered
completely white and clear pages. Nevertheless ink or writing spots and
those due to dampness were removed carefully.
Compared to today's techniques they seem to lessen the quality,
but as they are old documents this should not be a disadvantage!
The advantage of digitalisation is that an important document was saved
for the user, more so as these monumental folios are not allowed
to be taken home anymore (like nearty all the books dated before 1900).

The volumes are a digital copy (by Breitkopf & Härtel) of the edition by Peters, Leipzig,
available in a bound form at Leipzig Municipal Library with more than 16.800 pages
(section music, catalogue number D 17). Because of the size of the data the
pdf-formation was chosen (30O dpi) which can be realized by internet as
well as by PC or Mac®. The edition for the computer with 75 dpi can at once
be enlarged with very good results. lt is important to know that the print was reduced
from folio into legal.
Nevertheless it can be changed into all enlargements or diminutions you ever like.

With the programme Adobe Reader® all the data can be read
by PC vice versa Mac® quickly. This programme is added to the edition.
Laser prints guarantee for best legibility. The index (see textbook)
has got advantages, too: beeause of its clearness you can find items quickly on the CD's.
The "Ancient Edition by Bach" have their own indices which can
also be made use of for special items in panicular.
