For those who have not yet noticed, I have fairly quietly launched a new
web site for sharing manuals and other books related to HP calculators
at https://literature.hpcalc.org
As of this writing, after more than 2 years of work, I am hosting well
over 1,500 PDF documents totaling about 212,000 pages, taking over 37 GB
of space.
So far, I have personally scanned more than 750 books totaling over
94,000 pages. I scanned and processed all of these at 600 dpi and, with
few exceptions, produced 400 dpi OCR'd PDFs out of them.
Another 543 PDFs came directly from HP, with over 87,000 pages. For the
most part, these were at one point on their web site, but due to various
reorganizations, many of them have since vanished.
About 60 PDFs are original documents provided by the community, and not
scans. Finally, the remaining 160 or so PDFs were based on scans made
by others in the community, and cleaned up and turned into OCR'd PDFs by
me.
I now consider the collection to be substantially complete, with nearly
every English-language manual from HP scanned, and most of the popular
third-party books scanned as well. Over the next few months I expect to
finish scanning all the books already offered to me by others in the
community. My future goals for the site are to continue scanning new
books as I can obtain them, as well as to rescan some of those that were
scanned by others to produce higher quality PDFs. Manuals translated to
other languages have not been a priority for me to seek out, but I have
welcomed them when they have been made available to me.
A big thanks should go to Richard Nelson for lending me most of the
books I scanned, and to Adam Jones who coordinated with me as Richard's
collection was sent to him for resale. Secondarily, another big thanks
should go to Bob Prosperi who lent dozens of additional books to me to
scan. Finally, there are many others who have donated or lent books to
me to scan, ensuring my scanner has stayed warm the last couple years!
