Mark Goodacre has just updated his page of New Testament Bibliographies on his NT Gateway site. In addition to the links he provides there, I frequently consult the following as I am doing research. These are not all strictly NT bibliographies.
The Review of Biblical Literature site now has over 5000 books reviewed.
I also find that I often check the Logos Product Guides on such topics as: Cultural and Historical Background of the Bible, Comments on Commentaries, and Multi-Volume Commentaries. This last is particularly helpful in providing a brief summary of each commentary series and noting which commentaries are oriented to scholarly, pastoral, or lay interests.
Here is a helpful post by Phil Gons on commentaries which includes a pointer to the excellent BestCommentaries site. The BestCommentaries site provides rankings and reviews, and indicates whether the book is more technical, pastoral, devotional, or a specialized study. With a free registration/login, you can also note which books you already have in your collection and keep an online record.
Though it’s a bit dated (2001) and only available via web archive, Ralph Martin compiled an extensive bibliography posted HERE.
The Yale University Divinity School Library has an excellent collection of Reference Tools and Bibliographies related to the Bible HERE. Also note the Brief Bibliographic Introduction to New Testament Study.
