What is the correct punctuation for: The book had some nice features, such as: a hard-bound cover, a ribbon for a bookmark, and the author's signatures.

How about "Among the nice book's features were a hard-bound cover, a ribbon bookmark, and the author's signature."

OR... reverse it... A hard-bound cover, a ribbon bookmark, and the author's signature were among the nice book's features.

Now.... if you have further problems with sentences of this sort... see if you can do it and post it. Then we will make any corrections or suggestions. Hope this helps.

The correct punctuation for the first sentence would be:

"The book had some nice features, such as a hard-bound cover, a ribbon for a bookmark, and the author's signatures."

In this case, the colon ":" is not necessary since the list of features follows directly after the introductory phrase "such as." The use of a comma after "features" sets off the list.

For the second sentence, if you want to reorder the sentence structure, you can write:

"Among the nice book's features were a hard-bound cover, a ribbon bookmark, and the author's signature."

or

"A hard-bound cover, a ribbon bookmark, and the author's signature were among the nice book's features."

Both versions are correct, and the choice depends on the emphasis you want to give to the features or the book itself.
