Thank you, it was a nice project, partially walking down the memory lane, but also checking how many features in that version of Delphi are still core today -- not just for the product but for the industry

Which Delphi version(s) can the book be used with?

I like Delphi and FreePascal and Lazarus and have used all of them a little, now and then, to create some small personal and paid business apps, Delphi in multiple versions with gaps between versions, from 2 onwards until the 'Berlin' version, IIRC.

And yes, thanks, Marco, for making this book available. I had bought a copy of one of your Delphi books around the 3 to 5 version timeframe, cannot remember which version right now.

Also, I had downloaded your Object Pascal Handbook a few years ago, which is a great resource, because we devs need to know our programming language well too, not just the IDE or the libraries, which is what some book authors focus on. Thanks for that too.

Need to set aside some time to do some more Pascal work for fun and profit.

Memory lane, indeed! For me, as well - 25 years ago, I translated the Delphi 4 version of this book to Polish - I'm happy to see that both you and Delphi are still going strong!
