I need a dataset of books by title with their respective authors. I have tried the library of congress, but it seems as though you need a subscription to access its data? Are there any other website that would offer a dataset similar to this? I do not need every book, only a large sample.
There are lots of options, though Project Gutenberg is probably not one of them because of the time range. You could try using LibraryThing, Google Books (orderBy=newest), Goodreads or Amazon APIs to run search queries. Or try to get access to OCLC WorldCat or Ingram OASIS - talk to your friendly local librarian.
