While I was aware that the American Philatelic Society's Library (APRL) has a collection of stamp albums, I was unaware of any details as these are not listed in their online catalog. Fortunately, a recent entry in the Philatelic Literature & Research Blog gives more information. The collection, which is growing, at the moment consists of over 80 albums housed on 24 shelves. According to the blog post, "albums can be viewed in person, borrowed or pages can be copied or scanned from them as requested."
