Hello, SPGraham1957, and welcome to the ISFDB Wiki! I hope you like the place and decide to stay. Here are some pages that you might find helpful:

Note: Image uploading isn't entirely automated. You're uploading the files to the wiki which will then have to be linked to the database by editing the publication record.

Please be careful in editing publications that have been primary verified by other editors. See Help:How to verify data#Making changes to verified pubs. But if you have a copy of an unverified publication, verifying it can be quite helpful. See Help:How to verify data for detailed information.

I hope you enjoy editing here! Please sign your name on talk pages using four tildes (~~~~); this will insert your name and the date. If you need help, check out the community portal, or ask me on my talk page. Again, welcome!.--Dirk P Broer 21:06, 8 March 2020 (EDT)

Copyright Ddates

Hi, It has been brought to my attention that the copyright dates you look up in the Catalog of Copyright Entries are not the same as the actual publication date -which is the date we are after. When was it in the bookstore and could it actually be bought? I'm afraid we have to revert your edits.--Dirk P Broer 07:10, 24 March 2020 (EDT)

In your defense I have however found that "if the book is a first edition, the copyright date will be the same as the date published.", so we'd best check SF magazines of those days to verify the actual availability. With "The Door Into Summer" there is a big discrepancy between the date we had [1956-06-00] and the date you supplied [1957-02-07].--Dirk P Broer 11:14, 24 March 2020 (EDT)
Sorry for breaking in, we do not record the copyright registration date, the date field is for the publication date. Your edits for the seven Heinlein publications should not have been accepted. I'll revert them to their original dates, and move the copyright dates to the notefield. --Willem 15:38, 24 March 2020 (EDT)

Hi, I think there's been some confusion about the dates from the Catalog of Copyright Entries. In the online copyright database (, which includes entries from 1978, both the registration date and date of publication are given. But this wasn't always the case. In the pre-1978 volumes I've been using, only one date is given. An explanation of what this date represents is given in the volumes themselves. For example, the volume that includes the entry for "Double Star" is Jan-Jun 1956 (it can be found here: Page vii details the information that can be present for each entry. Item 13 is the "Date of publication as given in the application", no mention is made of the registration date!

Also some of the dates in the Catalog of Copyright Entries can be cross-checked against other sources to confirm that they are publication dates. Two examples are:

Heinlein - Rocket Ship Galileo: Heinlein's biography by William Paterson contains the statement (Vol. 1, page 437): "Rocket Ship Galileo came out on October 13", which checks with the date of 13 Oct 47 in the Jan-Jun 1948 Catalog of Copyright Entries.

Asimov - Pebble in the Sky: Asimov's autobiography "In Memory Yet Green" contains the statement (page 580): "On January 19, when Pebble in the Sky was first published...", which checks with the date of 19 Jan 50 in the Jan-Jun 1950 Catalog of Copyright Entries.

Based on this information, could you please re-consider your decision to undo my edits?

regards, Steve
