Hello @Dimity , @Appleblossom , @Bunniekins , @eth , @Shaz51
and other readers of this thread
I hope the following sources of information may be useful.
I entered the following search statements into PDFDrive.com which returned results on the titles available on the respective sites. It may be a good starting point for your own search for information available freely on the web. There is no cost for downloads from PDFDrive.com, and no limit on downloads. Another site, zlibrary.com, does have a download limit of 5 titles per day (from memory) and 10 with registration. I often use zlibrary if I cannot find a title on PDFDrive. I do a lot of research on these two sites and find them both very useful and the range of material, comprehensive.
If you have any queries about using either site, I would be happy to assist, if I can.
While it is not personal experience information and reflections, I hope that this information may be helpful for searches in these and other topics. Clicking on the links, on this page, will take you directly to the returned searches. When on the respective web pages, searches can be worded and structured to narrow or expand the available results. As you can see they are all "https".

I wholeheartedly agree with many of the sentiments about the cost of what is offered by many entities. Even to the point where, I believe, that there is, in many cases, an inverse relationship between the price charged and the value of what is offered by many so-called practitioners. At least we have the option to offer, what we believe may be, an appropriate contribution, where the services are provided on a foundation of principle rather than price.
By researching the various styles and methods, through the avenues above, one can seek out and approach potential providers with a reasonable foundation of understanding. Similar in some ways to comparing relative and relevant information, on a type of motor vehicle, before considering approaching the sales team.
Hoping the information will be useful,
With Best Wishes
