Is there any significance to the different series of ISBN numbers?  





They seem to run mostly in series tied to the copyright date.  Does a change in the series simply mean the previous series was out of numbers or does it signify a change in the company/printer/copyright holder/etc?

It means exactly that, the numbers ran out.  Companies buy batches of ISBN's depending on their needs.  The first allotment of TSR ISBN's was only 100 numbers, now it's somewhere around 10,000. In order from oldest number set to newest it goes like this.





Sometimes a change in ISBN will signify a company change, but that isn't the case for the D&D products.

Bumping this since I'm curious about something.

Did TSR put out products in numerical order for the last #'s of the ISBN, or did they skip around?

I've checked about 50, and while mods seem to not skip (i.e. B1 has a lower # then B2, etc unless a printing changes the code), some seem out of print order (unless again 1st prints had an earlier set from those I've checked.)

Shall have to see about kicking this idea around (and checking more ISBN's with the list of product lists etc.)

Any ideas though?

Typically when you decide to publish something you circulate the data (Title, stats, ISBN) well in advance. Sales/Marketing typically handles that, simply taking the next ISBN 'on the stack' for that series and assigning it to something. Stripped/sequential ISBNs are typically assigned to a specific group, e.g. novels, modules in sequence, etc.

Again typically, this all occurs before production even begins, before something is even written. Obviously production delays, marketing decisions to postpone items, etc. can thus result in a shuffling of ISBNs.

I was also interested in the ISBN's and wondered if there was any significance to the numbers.

The answer I got from our library personnel was "not really".
