Add books source other than Amazon and Library of Congress

Could you add cph.org as an add book source to help with adding the correct edition and format of an item. Also, add https://online.nph.net as another source. These two publishers publish books and different editions of books that are not always on Amazon or the Library of Congress.

Thank you!

There are almost 5,000 sources available. In order to be added as a source, the database has to use the standard access protocol. The people who add the source also need information about access.

If you can't find a source for your book, you can add the book manually. The link for this is at the bottom left of the add book page.

As noted on the Book Sources page, any data source (library or bookseller) that would be added needs to provide their data in a standard format that LibraryThing can ingest. This is basically called Z39.50 or SRU. Publishers don't tend to supply their data in this form.

If Library of Congress and Amazon are not good data sources for you, another one to try is LT's own OverCat. This contains data from any data source that has been imported to a catalog by another LT member. It can include individual libraries, including specialty ones that might focus on religious materials (the topic for the two publishers you mention).

If you were specific about a book you can't find, someone could probably identify a data source that has it.

And, yes, manual entry is another option for the very uncommon items.

Both would need to have Z39.50 connections to be used as sources. Do you know if either publisher is attached to a university or seminary? The library might be a source for these publishers if there is a connection. Even if the seminaries or university libraries aren't connected, you may have luck using them for book data. Also, have you tried Bowker Books in Print as a source?
