Gents you have very impresive libraries, plenty of new books ideas.
I was very fortunate to stumble upon this thread.
I took advantage of your pics and show them to my wife, so I prove her that mine is very small (some +260 including ebooks and PDFs by the incomplete Excel I started to avoid buying duplicates).
Her answer was that I lack quite a bit of them, so I guess that is a kind of encouragement to get some more, when budget allows.
BTW, last time I was able to go to my parents house (due to the f.ck.ing corona and associated mobility restrictions I'm unable to go for some time) I took those photos to start the aforementioned Excel, so they could be considered my library. Some of them aren't pictured but I know that I have them, somewhere.
It could be seem strange to have the books at my parents house yet, but since I lived here and there for some years in rentes homes I kept them there as a safe measure and, since I manage to "lost" some books (not aviation related), I think it isn't a bad idea so far.
