I haven't been a member of this site but for a short time, but I really enjoy this bottle site as being a collector, digger, book contributor and researcher for more years than I willing to say. I came across this very informative general knowledge site that will help with new-comers to the fascinating world of bottles. Many people just starting out in this hobby will really benefit from the more in depth information they can acquire at this site. This link is for educational purposes only and not intended to replace or lessen the importance of this site which is the most friendly and socially interactive site I've became a member of. http://www.sodasandbeers.com/SABBottleClosuresSoda.htm
