If you're hunting for Connie Sheeran Griffin books or ebooks, I usually start with the big storefronts and work inward from there. I check the Kindle store, Apple Books, Kobo, and Barnes & Noble first because if the title exists in ebook form it's often listed there. I also run the author's name through Google Books and WorldCat to see library holdings or alternate editions — WorldCat will tell me which local or university libraries have a copy, and that makes interlibrary loan an easy next step if the book is rare.
When a direct vendor search comes up empty, my next stops are the author's website or social channels, plus small-press and indie bookstore sites. Lots of authors sell ebooks directly via platforms like Smashwords, Draft2Digital, BookFunnel, or even Bandcamp-style storefronts. If a book is out of print, I look for print-on-demand options through Lulu or Blurb, or used copies on AbeBooks, Alibris, and eBay. For free or archival copies I respect legality and check the Internet Archive and library apps like Libby or Hoopla — sometimes a title is available there through library licensing.
A few practical notes from my own experience: note ISBNs when you find a listing so you can cross-check editions, watch for DRM differences (mobi vs epub vs PDF), and if you need to convert formats I use Calibre for personal convenience. If nothing turns up, sending a polite message to the publisher or the author via their contact form often yields a quick answer about availability or upcoming reprints. I usually end up bookmarking whatever lead I get and signing up for the author newsletter so I don’t miss announcements — it’s saved me from missing limited runs and signed copies more than once.
