Hello All... I have never heard of any library that has a membership to Ancestry.Com that they have available to the public...LDS does not have this in their libraries either... LDS has access to all the microfilm tapes that you can arrange to rent for a period of time and have it sent to the LDS Library of your choice for a fee...they have reader machines available to use as well as machines that will make copies of the pages that your information is on... On the Internet you can gain access to the LDS Genealogical Website called Family Search and alot of images to census reports and other information is availble there for research...but for the most part you need to go to the LDS Family History Centers, (FHC) are located at the LDS Churches...they can be used by anyone... Some of the larger FHC do have a large amount of microfilm tapes that they maintain on site of the Census reports and Soundexs, one of the best ones that I have been to is the one located in Los Angeles out on Santa Monica Blvd.... Of course the most famous is the Genealogical Library in Salt Lake City, UT...I had an opportunity to spend 9 - 8 hr days there a few years ago and it was fabulous...but I can say, except for the books, that have not been microfilmed, you can order everyone of those tapes to come to your local FHC through out the year... Good luck in your research and may all your Ancestors turn up in the near future... LINDA...Oregon
