Hi, I have used at least five numbers for numbering when I know I will eventually have a huge database of something such as Marriages. I use marr00005, News00010, Cem00102. It will not take long to have more than 100 or 1000 records of some events. For census records I took an idea someone on the list suggested and it has worked great so far: state year, hyphen, number for example TN1850-0001 and then I have a census notebook for each state. Right now it is one big notebook with dividers for each state (states I have census records for) and as I add census records it will develop into a note book for each state (probably about 12-15 states for me). This has been simple to find in the index- just go right to TN rather than having to look through census records 0001, etc.- cuts to the chase. I think I will go back and adopt Cathy's idea for Marriage records, etc. and list the event out rather than birth, death, etc. Seems like a great idea and will also be able to know at a glance if I have the record I'm looking for and then can go straight to the notebook for the document. For those of you who haven't started using Clooz just jump on in. I'm a very disorganized individual and have 17 years of accumulated "stuff" all over my house and Clooz has been a tremendous help in organizing. I do a little bit several times a wk and I have manually added individuals as I've needed them. I have not gotten overwhelmed. In fact, I've enjoyed having control over my mounds of paper- still a major work in progress- but I see there will be daylight at the end of the tunnel. Happy Hunting and Organizing, Margaret
