Book lovers enjoy lots of things, especially if they are related to books or reading. I've compiled a list of stuff directly and indirectly related to books and book series. Not all of these may apply to every reader you know, but I think there's a wide enough variety to get you away from books that you may find something new and unique that other friends might not have thought of. Most of these apply to a wide range of books, but some only have pieces for major book series. I hope you have lots of fun shopping for yourself and others and that gift giving becomes a little bit less stressful!
1. Bookmarks
Bookmarks are always a good choice for the average book lover. If they like to read, chances are they'll need one. Not to mention there are tons of fun varieties of bookmarks!
2. Book duct tape
Duct Tape has a lot of types. There's an almost guarantee that there will be something in there your friend will like and they could use it to fix and repair book spines, make water proof book sleeves, decorate their bookshelf, and more.
3. Bookends
Bookends may be useful for those who have room on their shelves or will make room so the can use these awesome pieces. Bookends come in many shapes and forms and are a great piece to fancy up those bookshelves in the living room.
4. Posters
Posters are a nice gift and most books have them. They come in a range of sizes and styles, and the artwork can range from the book's cover art to fan-made artwork, depending on the stores you look at.
5. Fandom Jewelry
Lots of popular books often have inspired pieces of jewelry. These come in a variety of forms: earrings, necklaces, bracelets, rings. If you know your friend is interested in a popular book series, that'd be a good place to start looking for fandom jewelry.
6. Fandom Subscription Boxes/Magazines
If your friend likes a wide range of books, you might want to look into buying them a short term subscription to a magazine or subscription box dedicated to books of their type of fandoms. Personally, I like the Fandom of the Month subscription box.
7. Collages
If you're feeling creative, you could make a collage of their favorite books, book quotes, book art, and add other more personal friend stuff. It's a nice creative way and cheap. All you need is a computer, printer, cardboard, glue, and some time.
8. Fandom Clothes and Scarves
If you know or are good at estimating sizes, you might want to look towards the clothing section of book items. Ranging from quotes to art, there are plenty of choices in t-shirts, dresses, scarves, and socks.
9. Fandom Inspired Food
Nothing says love more than delicious food! Cakes or cookies could be decorated with some type of book icon or spell out some type of quote.
10. Fandom Inspired Party
If you are a good organizer, this may be a good gift idea. Throw your friend an awesome party with the theme of his favorite book. Go as big or small in the details as you like.
11. Book to Movie/TV Adaptations
If one of you friend's favorite books has been adapted into a movie or TV series (and your friend enjoys it), then buying her the DVD of whichever provides her another way to enjoy the book series she so loves.
12. Funko Pops
Funko Pops are a fun little gift to give a friend. There is a wide variety of these guys, spanning most of the popular books, TV series, and movies.
13. Gift cards
There is really no way to go wrong with buying a gift card for readers. You can get them from online or local bookstores or book-inspired stores like Red Bubble that sells book-ish style pieces.
14. Bags
Bags are always helpful, especially when lugging around piles of books to read. This is a great gift that will be useful and cute.
15. Signs
Signs can be placed pretty much everywhere, and are a nice simple gift that comes in a variety of styles and fonts. They are pretty easy to make yourself or get customized.
16. Mugs
Everyone loves hot chocolate, tea, coffee, or other hot drinks that mugs would be perfect for. Provide a nice mug for your friend to drink out of as he reads his favorite book.
17. Candles
This may sound odd, but there are candles that are themed by books. The scents are wonderful and will hopefully remind your friend of her favorite book.
18. Book Lights
Helpful to all readers as they read one more chapter before bed that inevitably results in a night long binge -reading session.
19. Earphones
Some readers love to listen to audio books; others like to listen to music while reading a book in their lap. Regardless of which, a set of earphones would not go amiss to help them keep listening to their favorite stuff!
20. Pencils
These are nice for the readers still in school, especially. Nothing more inspiring during a test than pencils telling you your favorite book quotes!
21. Notebooks
Especially nice for students in school, but are usable by pretty much everyone. Notebooks are a fun way to express your love of reading while still being useful for everyday things.
22. Calendars
Calendars are a good bet for alternative presents. Big or small, calendars help readers keep track of how many books they read a month.
23. Ornaments
Ornaments are a good holiday present. They're fun, small, and a nice addition to everyone's holiday spirit.
24. Magnets
You can get magnets pretty cheaply either pre-made or customized.
25. Lip Balm
These lip balms do double duty for your lips: helping them and bring a smile to them. This is a fun little gift that lots of people may like, not just readers.
26. Make-up and Nail Polish
If your reader is into make-up or nail polish, then she might appreciate colors inspired and named after a character or place or whatever else related to her favorite book series. Or if you also like it, maybe do make-up or nails for each other with a book theme.
27. Pillow
Pillows are nice for when readers curl up with a good book. You can buy one yourself or make your own pillow cover.
28. E-Reader Cases
If your friend enjoys e-books, then they probably have a nook or kindle that would love a new cover.
29. Transparent Book Weight
If your reader likes reading outside or with food (and has the knack for spilling), this is a good gift option.
30. Clock
Readers often get lost in fictional worlds for hours, so it'd be good to give them a clock to at least pretend they are aware of time.
31. Fandom Themed Board Games
If the book series is big enough, chances are there will be some type of board game made with the book theme. This is a good way to encourage a reader to socialize but still have the comfort of books.
