Introduction

Beginning in May 1986 the North American AstroPhysical Observatory (NAAPO) began publication of a newsletter which was mailed to a list of persons selected by the NAAPO Coordinator, Dr. Philip E. Barnhart, with suggestions from other members of the group.

The name of the newsletter was "NAAPO News". This name was used from Volume 1, Number 1 (May 1986) through Volume 3, Number 9 (April 1988). Starting with Volume 3, Number 10 (May 1988) the name of the newsletter was changed to "Signals".

Beginning with Volume 18, Number 1 (February 2002) "Signals" was no longer mailed to a list of subscribers. Instead, that and subsequent issues of "Signals" were written for the public and placed in our publicly accessible website www.naapo.org (where you are now located).

In addition, most issues within Volumes 1 through 17 were scanned, converted to browser-readable text and images, and put onto this website.

Thus, this website contains two kinds of newsletters:
Group 1: Those prior to Volume 18, Number 1 (February 2002); and
Group 2: Those starting with Volume 18, Number 1 (February 2002) and continuing to the present.

Below is a description of each of the two groups.

Group 1 Newsletters

These newsletters were originally available only as printed documents; no electronic versions were available. We believe 106 newsletters were published but we could locate only 103 of them (i.e., 3 are missing or otherwise unavailable). These printed newsletters were edited by a number of different editors and printed using several computers, word processors, and printers. For each newsletter a master black & white copy was printed and then photocopied ("Xeroxed") onto colored paper (the color of the paper was changed from one issue to the next).

I (Jerry Ehman) volunteered to convert the printed issues into electronic versions. After scanning in each page and each photograph, illustration or other graphic, I used OCR (optical character recognition) software to convert the text within the scanned images into editable text, which was proofread and reformatted in several stages. The photographs, illustrations and graphics were typically resized (sometimes resized twice to obtain both small and large versions). From these operations an HTML (HyperText Markup Language = browser readable) document was prepared. Then, a PDF (Portable Document Format) version was also created.

Note. On occasion, particularly when there was a spelling error or some other error in the original printed newsletter, I did correct that error. On other occasions, a correction to or an explanation of a statement in the newsletter may have been necessary. Using a red font I inserted such correction or explanation within square brackets. However, ordinary spelling errors were typically changed without notification.

Group 2 Newsletters

These newsletters were designed to be immediately placed in this website, without the need to be converted from printed versions. I (Jerry Ehman) received from Phil Barnhart (our NAAPO Coordinator) typically a Microsoft Word document in electronic form. I then reformatted it and put it into HTML format. I used various color backgrounds to distinguish one article from another. I then also created a printer friendly document that eliminated the color backgrounds so that a reader who desired to print out the document would not use up much color ink or toner. I also decided not to prepare PDF versions because modern web browsers can achieve most operations of the PDF viewers without having to go through an extra step of invoking such a viewer.

To View the Newsletters

The two groups are accessed separately. Below are two links, one for each group. Each link takes you to an introduction and volume menu for each group. Once a volume is chosen by clicking on the appropriate link, you will be presented with links for the list of all issues in that volume. In Group 1, for each issue, you will choose whether you want to view an HTML document or a PDF document. For Group 2, only an HTML documnt is available (although after you are in the document with the color backgrounds, you may then choose the printer friendly version.
