I read a bunch of other blogs. One of my favorites is “The Ancestry Insider.” He used to work at Ancestry.com but now works at Family Search. The ‘Insider’ has been running a series of postings about Citations; ie. recording the sources that you have for your information. He is planning a few more postings in the series but these are what he has written so far:

• Forward.
• Citations Have Two Purposes: locate the Source and communicate its strength.
• Is Mills Style Necessary?
• Cite the Source You See.
• Citation Principles: What is a Derivative?
• To characterize the strength of a derivative source, Specify the Source of the Source.
• Citing Quoted Sources.
• Emphasize the Source You Used Over the Source of the Source.
