While no other text can claim this same unique authority, 
Apocryphal and Pseudepigraphal literature such as contained in the first
 volume of The Researchers Library of Ancient Texts (Volume One—The 
Apocrypha: Includes the Books of Enoch, Jasher, and Jubilees; also 
available on Kindle), provides literature that often precedes or follows
 the chronology of biblical texts, which frequently are used or assigned
 as supplemental works within academic settings to help students and 
scholars discover or better understand cultural and historical context 
within the Word of God. Whether or not the information contained in the 
apocryphal literature is entirely precise—as is the canon of 
Scripture—these ancient texts provide commentators’ valuable insight 
into what many ancient Jews and early Christians believed when, “God, 
who at sundry times and in divers manners spake in time past unto the 
fathers by the prophets” (Heb. 1:1). "First Esdras contains the 
whole of Ezra with the addition of one section; its verses are numbered 
differently. Just as Ezra begins with the last two verses of 2 
Chronicles, 1 Esdras begins with the last two chapters; this suggests 
that Chronicles and Esdras may have been read as one book at sometime in
 the past. Ezra 4:6 includes a reference to a King Ahasuerus. 
Etymologicaly, Ahasuerus is the same as Xerxes, who reigned between 
Darius and Artaxerxes...in 1 Esdras, Cyrus the Great, Darius the Great, 
and Artaxerxes I appear in their historical order." --Wikipedia The
