Many of us who have been doing genealogical research for a while are very familiar with the various Research Outlines published by the Church of Jesus Christ of Latter-day Saints. These are no longer being published in print form but there is good news. You can turn to the new Family Search wiki to find a lot of that same information and new updated information as well. To get to the wiki click on this link. Family Search Wiki
While much of the information found on the wiki is good and sound, please remember that all information found on the site is user-contributed. That means it is only as good as those people who contributed it. I think you will find a lot of helpful information here to help you in your research. Many of the employees of the Family History Library in Salt Lake contribute articles that will help you in finding sources and knowing where to look.
Good luck with your research!!
