Some extra information, according to your questions
This is the description of the document as in the library catalog. To describe documents (books, reports, serials etc.) there are international guidelines, which believe it or not are very comprehensive as it has to comply with all nations, languages etc.
One of the golden rules in cataloging that the document is taken at face value - what's on the title page that's the source, no more and no less. What you see in this catalogue description is that certain data is between parentheses (
[...] ). These data were added by the cataloguer, but cannot be found on the document. Perhaps there were other secondary sources to describe the document.
Sure the catalogue is in German and presents -
- Title
- Subtitle [
Titelszusatz]
- Publisher [
Verfasserangaben]
- Data about place, time [
Impressum]
Here
s.l . means 'sans location' (French) - that's no location of the publisher / printer is given in the book
o. Verl. means ohne Verleger (without publisher), not given anywhere in the book
- Number of pages [
Umfang]
79 S. means 79 Seiten ( = pages)
You see the exact description of these books is quite a work
In the meantime I have found also a
1916 edition of the B.L.V.
After the end of the war the IdFlieg published a commemorative book -
Geschichte der deutschen Flugzeugindustrie, which might be very interesting for you. It is in two volumes and dates from summer 1918.
The second volume deals completely with the different Bauaufsichte 1-45.
A last one, as you have difficulty reading German, it might be a good move to turn first to the brilliant study of John H. Morrow Jr. German Air Power in world war 1, ISBN 0-8032-3076-1 which is very heavily based on German original archive documents. This study is mostly about the economics, organizational study, politics (!) and far less on the actual aircraft.
Appendix 6 The Construction Inspectorates (Bauaufsichten - BAs) and Their Factories, Summer 1918 gives a comple list of these (probably based on the second volume of the IdFlieg historical work).
Incidentally BA 28 is given as the Euler-Werke, Frankfurt am Main
Have a fine day
