Book Guidelines

Listed Page Count

Use the page number printed on the last page of the book.

This might not be the same as the physical number of pages, which might include unnumbered pages at the beginning or end of the book.


Dates should be added in the format YYYY, YYYY-MM, or YYYY-MM-DD.

Try to be as precise as possible. If the exact date is unknown just the year is sufficient.

If more than one date appears on the book, please include them all.

If you add only one, please ensure it is the latest copyright date.


This information can often be found on the book's copyright page, or the back cover.


Enter the physical dimensions of the book. Select your preferred unit of measurement from the dropdown menu on the right.

Please link a Discogs artist, release, or label page where there is a commonality with the data or it makes sense to do so.

Adding a YouTube link here will display the video in the right-column (this could be an audio recording or other video related to the book).

We don't accept links to review pages, email addresses, shops or online stores, poor quality fan pages, or pages that are not directly accessible (e.g. require a log in or payment to view).


This describes the physical form of the book (e.g. paperback, hardback, journal)
