PDF files are okay for an alternative to mailing paper. If a family member cares about helping with the family history or editing data to print an updated book they will need to use the same genealogy program, data files and pictures. PDF files usually default to very small print that is further reduced in size by a page-turning printer or fax. If you are saving reports with a mix of color pictures, check the cost of printing. Nearest copy service charges about ten times the amount of a BW copy if a file is printed in color. Grouping of color pages can be planned but a family book might have a color picture on nearly every page. My best research contact with a Mac didn't want to deal with PDF files so I printed 30 pages of pictures for her showing our combined 90 photos and source documents.

I "saved to file" to PDF printer, then copied to CD.
