Digital Reaearch Library

Here, in one place, are all the manuals we have for Digital Research software products. These manuals have been produced by scanning, and ocr'ing, the originals. Where possible, the look and feel of the original has been preserved as much as possible. The manuals presented here have been through an extensive clean-up process. OCR is not an exact art, at least not in the affordable software available for the PC, so a seperate cleanup process is necessary to produce a pretty manual.

At the bottom of this page you will see a link to some manuals that have been scanned, and ocr'd, but not cleaned up. You can also participate in getting these manuals cleaned up.


Caldera owns the software, but I consider these manuals to be public domain. They should not be sold; only given away. Note that Caldera still owns the software. It may be used freely for individuals, and non-profit use. If the software is used for commercial use, you must contact Caldera for a license. The manuals are still free.

NOTE : Due to space restrictions, this site will no longer present manuals in PDF format, or HTML viewable on-line. Any available HTML manuals will be backaged for download, and use on a local hard drive only. Sorry! The space for this site is donated by our hosts, and we must be careful of the amount of disk space we use.

I am sponsering a user program to get manuals prepared for distribution. I will scan, and OCR, them, and post the results here. I will then work with anyone who will volunteer to clean them up, and make them presentable.

If you would be willing to help, please check out what I have scanned, download it, and go to it. If you do, PLEASE co-ordinate with me so we don't have several people working on the same manual.

If you are desperate for a manual, you can take one from this page and try to use it. Just understand that it won't be pretty.

Most of the problems introduced by the OCR process are pretty straightforward. For those that aren't, there are several ways to address them. If you have another copy of the manual you are working on, you can refer to it to fill in the blanks in problem areas. If not, you can contact me, and I will re-scan the problem pages, then email them to you in TIFF format You can then either view them on-screen, or print them out. You will then have a copy of the page in question to refer to. I will only do this on selected pages as the TIFF files are huge.

This will be a community effort. When you get something done, send it back to me, and I will post it. Some have already been done this way, and are now available for use. :=)


Here's a list of what I have in-stock in the way of manuals. This list may be incomplete, but it will be close. If there is something on this list that you especialy want, and the scanned data is not present below, drop me a line, and I will try to get it scanned next.
