When I use a source such as will or intestate probate records, etc. I try to always include where the original record can be found giving the address of the county courthouse and the office where the record is located, such Probate court, etc., and if the record has been transferred to an archive the location of the archive. I also include the on-line site where microfilm of the record can be viewed. This way if the microfilm record is ever pulled from the on-line site, or the on-line site ceases to exist, a person can then travel, and/or contact the site where the original record is located to either view the record or obtain copies.
