Thanks for the sympathetic shoulder, Sherry. I have Verizon Broadband, which uses Internet Explorer. I got to keep my AOL account for free when I switched to Verizon.
I've had AOL for about 15 years with no problem, but they've been dicking around with things lately, like the basic appearance of e-mail messages, which I'm not too crazy about. I don't think it would be possible to delete a whole address book without knowing, because in order to edit any entry you have to click on each name individually and hit "Edit" first. Unless my memory has truly failed me, I think I would have remembered editing 9 pages of names. Personally, I think they've taken my contacts captive for ransom.
I have a lot of saved mail with lots of addresses, but the sad part is I had some of my Mom's relatives' addresses that I entered, and threw away the envelopes.

If the list is truly gone, (I'm going back to peek now

) I'll retrieve what I can from saved mail and phone calls, and accept the fact that it was time to separate the wheat from the chaff and scale down my contacts.
I'm also going to see if I had printed out the list. You're right about having important things in more than one place.

Earlier this year, I went to my cell phone dealer's and had them print out a list of all my cell phone numbers. My sister-in-law lost her phone (she drowned it, don't ask

), and she was truly lost. I learned from her problem. Hopefully, people will learn from this.
Again thanks for your suggestions.
