White Rock Science has adapted a policy of not including printed paper copies of manuals with the software distribution. An electronic version of the manual, in PDF format, is provided on the distribution CD.

Adobe Acrobat Reader software to read (and print) the PDF manuals is freely available.

Printed Sabrina and BodyBuilder manuals may be purchased at additional cost.

The electronic manuals offer many advantages over paper manuals:

• Extensive hyperlinks permit jumping to references within the manual, from entries in the Table of Contents, and from references in the index.
• White Rock Science manuals are prepared with Adobe FrameMaker that is designed to work with Adobe Acrobat in producing quality PDF documents.
• Color figures are presented in their true colors. Areas of solid color do not suffer from degradation often seen in the printed version.
• The shipping weight for Sabrina and Moritz is significantly reduced, as is the shipping charge.
• International shipments can be sent as a letter, rather than a package, possibly resulting in less scrutiny by border officials.
• Preparation of a printed manual adds 2 to 5 days to the time required by White Rock Science to ship an order.
• Letter sized packages may be delivered more quickly than larger packages.
• The PDF docuemnt may be freely copied, permitting each user to have a copy.
• Sections of the manual may be printed as desired.
• Institutions with in house printing capability will most likely be able to produce better hardcopy than from White Rock Science's printer.
  
• Fewer resources are used.
