Time for a comment.
(a) caveat - I don't have any background on the Airbus so I am only able to talk generically.
(b) document provenance is extremely important - the internet is a useful place .. but has a lot of garbage interspersed amongst the useful stuff .. are these manuals purported to be downloaded traceable back to the OEM or not ?
(c) copyright is a consideration of note. Take care lest the OEM smite thee via legal sanction. The OEMs charge a hefty price for manuals so there is a real risk that the OEM may pursue folk who do the wrong thing.
(d) most civil manuals cover a range of serials and it takes some care to sort the wheat from the chaff when using them. Just part of the routine workload in the Industry.
(e) tailoring a generic manual to specific serials is not difficult - just a matter of dollars
(f) avoiding confusion is why the militaries tend to prefer tailored manuals
