Guidelines for Information Providers

Select items (35 mm slides, prints, flat art, video, sound) that have exceptional value in illustrating or developing a concept, principle, phenomenon, or process in your field. While you may think your image is common place, a student or an instructor at another school may be delighted to be able to use the image in lecture, lab presentations, projects, or handouts. Consider how the material can be used in lecture and lab presentations, or for student use via a computer when choosing your images.

Once the material has been selected, it should be organized into sections. We recommend no more than ten to twenty images per section so as to provide ample material to illustrate a concept without overwhelming the learner. A section may also include audio or video material as well. Unless self explanatory, each image must be accompanied by a short description. Due to staffing considerations, we would prefer to receive your submittals in the digital formats described below. However, we understand you may not have access to equipment or the technical expertise to convert original material to a digital format. We can provide assistance in the conversion process with the understanding that there may be a delay in the time your material is available to the Global Campus. When possible, submit duplicates of digitized material to safeguard against loss or damage. We are not responsible for loss or damage of material

Formats

The following guidelines represent how material is distributed in the Global Campus database. Distribution of materials to the Global Campus will be expediated when provided to us in the following formats:

Textual Descriptions

Provided in plain ASCII (text only, no formatting codes) files, one for each media item submitted. Here is an example of a description accompanying an electron micrograph of renal tissue:

	Thorium in Cellular Vacuoles (d)

	Micrographs showing numerous vacuoles containing accumulations of
	thoriumdioxide particles. The vacuoles occur in the cytoplasmic extensions
	of the cells in the renal epithelium and can contain either fluids or a
	ground matrix of moderate electron density.

As you can see the text is informative yet concise.

Still Images

Submit both a full size JPEG image and a thumbnail sized GIF image.

JPEG: The Joint Photographic Experts Group format is used to display the full image. JPEG images should be between 640 and 800 pixels in the longest dimension.
GIF: Since JPEG images cannot be viewed in-line, files in the Graphics Interchange Format are used to provide in-line thumbnail imagtes for WWW browsers such as Mosaic or Netscape. A recommended size is between 80 and 100 pixels in the longest dimension

Sound

Sound files should be provided in AIFF or AU format. Contact us if your sound files are in a different format.

Video

Video files should be provided in Quicktime or MPEG format.

Quicktime: Format available both on Mac and Windows machines. We recommend using Cinepak compression on your Quicktime videos.
MPEG: Moving Pictures Expert Group standard for video compression.

Digitized Media

We accept digitized material delivered via anonymous ftp, Syquest Cartridge ( 51/4 inch,44,88,or 200 MB), 3.5 inch diskettes, DAT tape (4 mm., formatted as Retrospect (from DOS or MAC) or tar (from Unix)), CD-rom, audio CD, Photo CD, HFS, or ISO 9660 (Uni x orDOS).

If you are unable to provide your information in a digitized form, please contact us for assistance.

Filename Conventions

Each media item should be assigned a unique sequence number that should be part of the Filename. Use extensions to identify the filetype. Examples follow:

For images:

Amoeba01.txt	descriptive text
Amoeba01.gif	thunbnail picture of amoeba
Amoeba01.jpg	full size image of the amoeba

For audio:

Dog01.au or Dog01.aiff	audio file of dog barking
