Is this a valid source? U.S. and International Marriage Records, 1560-1900

Question

Source Information Yates Publishing. U.S. and International Marriage Records, 1560-1900 [database on-line]. Provo, UT, USA: Ancestry.com Operations Inc, 20

Would this be a valid source? It is from Ancestry. 

Just saw the answer I think, so thank you

Answer 1

As you probably saw in previous questions, it is not a Primary source, but it can be a source that might give you information to find the primary source.  The source name is very deceiving, but it is not much more than what was gathered from people's family trees that are not sourced.

Thank you

Answer 2

It sounds like a published book that takes you to transcribed information rather than the actual marriage document. It therefor would be a repository of secondary sourced information. Secondary sources are valuable to your research. Not all of your sources would be of primary quality. The marriage certificate itself would be a primary source.
