    My home page has nothing in it except links to other pages of mine dealing with different aspects of international auxiliary languages, which are an interest of mine. This home page exists just to satisfy the server on which these pages reside and may not always be up to date. Some of the scans, PDFs, and other files may be somewhat large, so I have given some approximate sizes, in kilo/megabytes, in parentheses. Some of the scans are photo-image type PDFs in "rough" form, meaning that they may show fingertips holding the documents down, portions of the scanning bed, and so on. I do not have the software (or the time and energy) to crop and re-orient some of the documents. In the format in which I have some of them, they are not searchable. Some of them were printed on paper which is now badly yellowing.

    Note that it is possible that some of these works may still be in copyright, or that they are "orphaned" works whose copyright status is unknown to me. Therefore the legal status of copying and/or distributing some of them is undetermined. There may be legal implications in using some of these files.
