While "noodling" around the Brooklyn NY Library site I came across the Brooklyn Jewish History Project. No library care is needed to access.
There are many pages of family photos and documents. As an example there was a 1905 passport for Josel Silin.
Some of the documents and photos are labeled, some are not. However, if the photo or document is clicked-on, there is a complete explanation with name, date, etc.
Perhaps those who are looking for Brooklyn family will find something here.
