Steve, If you are sending them to a stock house or publication for spec then label them with all pertinent data including copyright and your personal info such as email and phone number. I would leave off the date unless they ask. If there is subjects such as wildlife, the Latin name is very professional. If you are sending the slides to a customer, such as a wedding or function, then just copyright with your personal info. Make sure to always add your email address. There are over 8 million emails sent everyday and that number continues to grow. Take care, Gregory david Stempel FIREFRAMEi m a g i n g www.americanphotojournalist.com
