I'm looking for a simple database program I can use to index individual series in comics, so I can easily check when a particular series ran, what issues it appeared in, and also link it to sequels, if any.

My expertise with such things is limited, so I wondered if anyone could suggest something.

I've never used it but comicbase was the one that used to be talked about (on the odd occasion that it has been).

Collectorz is the other. No idea how well they work for Brit comics.

Thanks, but I don't think programs designed for American comics are going to be a good fit, since they don't really have a tradition of serial anthology titles. I was thinking more of a simple, customisable, general database I could adapt to the task, rather than something optimised for the wrong sort of comics.

I would have thought a spreadsheet might be the easiest.

Although spreadsheets can be used to create databases, but you'd be better off using proper database software. I don't know which computer operating system you're using, but on Windows a program like Microsoft Access would be suitable. You could use it, or similar software, to create the appropriate fields and then add the data you want to include - also, you can search or query the data a lot more easily than in a spreadsheet program like Excel. I hope this helps.
