I am little confused on usage of "by", so below sentence is grammatically correct ?

Notes by Ajay.

I am going to start a blog, the website name I came up as notesbyajay.com, However my friend suggested that this was incorrect and it should be "Notes from Ajay".

Here, Notes - Pages/Blogs on technical articles created by me.

    I've answered, but can you explain why you doubt this to be incorrect? Why are you confused by "by"? What has confused you?

  • Blogs are usually in the first person so I would not use that tag for your blog.

  • As an aside "Notes by Ajay" is not a sentence. A sentence is something that has at least a subject and a main verb.

    Also, correct question structure is Is "Notes by Ajay" grammatically correct?

It is not a "sentence" because there is no verb. But the implied meaning "These are notes by Ajay" has no errors. "Notes from Ajay" has exactly the same grammatical structure and is equally correct (but with the meaning of "from" instead of "by".)


"By" is probably the most typical preposition to indicate authorship. "Notes by Ajay" suggests that Ajay wrote the notes. "By" can also be used for other forms of creative work, and many business names follow the pattern "PRODUCT by NAME" ("Cakes by Ajay" for a bakery, "Hair by Ajay" for a hair salon, etc.).
