The Federation of Swedish Genealogical Societies maintains an excellent web site that offers a multitude of information on researching Swedish ancestry. Some of the items of information include photos, provinces, emigration and birth and death records to name a few. There's even an English-Swedish dictionary to assist researchers. A site that is very much worth utilizing for anyone with ancestors from Sweden!
Hint: When you land on a page in the site that contains information in the Swedish language, be sure to hit the 'flag' button in the upper right hand corner of any page. This allows the viewer the ability to read the page in Swedish or English.
