This ASL word/sign is general, but you can adapt the classifier to be more specific for a type of a bookmark, such as a paperclip-like version.
Meaning: A marker for finding a place in a book.
Pronunciation (sign description): The palms of two-handed flat hands hold together, then they open while the bottom edges of the hands remain together. Then, dominant "H" with palm up moves toward between the thumb and forefinger the non-dominant palm-up flat hand.
Variation: To be more specific, you can use some different classifier for a bookmark, such as the one that is more similar to a paperclip.
Vocabulary

Alphabetical letters: It's useful for 1) a single-letter word (such as A, B, etc.) and 2) very short words (e.g. "to", "he", etc.) to narrow down the words and pages in the list.
For best result, enter a short word in the search box, then select the alphetical letter (and page number if needed), and click on the blue link.

Don't forget to click "All" back when you search another word with a different initial letter.
If you cannot find (perhaps overlook) a word but you can still see a list of links, then keep looking until the links disappear! Sharpening your eye or maybe refine your alphabetical index skill. :)
Add a Word: This dictionary is not exhaustive; ASL signs are constantly added to the dictionary. If you don't find a word/sign, you can send your request (only if a single link doesn't show in the result).
Videos: The first video may be NOT the answer you're looking for. There are several signs for different meanings, contexts, and/or variations. Browsing all the way down to the next search box is highly recommended.
Video speed: Signing too fast in the videos? See HELP in the footer.
ASL has its own grammar and structure in sentences that works differently from English. For plurals, verb inflections, word order, etc., learn grammar in the "ASL Learn" section. For search in the dictionary, use the present-time verbs and base words. If you look for "said", look up the word "say". Likewise, if you look for an adjective word, try the noun or vice versa. E.g. The ASL signs for French and France are the same. If you look for a plural word, use a singular word.
