Why is so hard to find a print version of ASV bible? I started to study the bible recently, and I wanted to buy a print copy of the American Standard Version. The bible is available online but I wanted a print version as a backup. To my surprise the bible is out of print. I looked online for print copies and only found one or two sellers. Why is this bible not widely available in print form? Is it because of the expired copyright? The KJV is in the public domain outside of the U.K and is available in print form. It is difficult to find a second hand copy as well, even though I understand that millions of copies were printed in the past.
The primary reasons that this translation is relatively difficult to find in hard copy are:

It was never especially popular to begin with
It was superseded many years ago by much more popular translations

Initial popularity
The ASV is based on the English Revision (1881–85), a version meant to revise the King James Version for use in the Church of England. However, people continued to prefer the King James, and so the English Revision was not particularly popular, and neither was its cousin the ASV (1901).  H. L. Wilmington writes:

Although it enjoyed better permanent reception than the [English Revision], it still has not seriously cut into the lead of the King James Version. (Guide to the Bible, 809)

Interestingly, in part because of its use of the word &quot;Jehovah,&quot; the ASV did achieve popularity with one group, the Jehovah's Witnesses.
Subsequent translations
The ASV's popularity declined even further as new translations appeared.  The Revised Standard Version (1952) dropped the Elizabethan style of the ASV, making it more accessible.  It was the first serious challenger to the KJV, and was used by Protestants and Catholics alike.
Not long after, other translations appeared based on the ASV.  The New American Standard Bible (1971), for example, quickly displaced the RSV in conservative circles due to perceived textual issues, and it is still a top-ten Bible translation.  Similarly, the Jehovah's Witnesses largely moved on to the New World Translation (1961).
Concluding thoughts
One of the main reasons people today use the ASV is due to its public domain status: it is freely available in many Bible software packages and online.
However, this popularity does not carry over to print copies.  Relatively few used copies exist because the ASV failed to supplant the KJV early on, and it was largely replaced by more modern translations over 40 years ago.
Michael C. Armour, in A Newcomer's Guide to the Bible, describes how the ASV simply didn't find a niche—it is too different from the KJV for purists, but too similar to it for most modern readers:

Due to the great popularity of the King James Version, with its Elizabethan English, the translators of the ERV and the ASV felt they needed to retain the Elizabethan style.  This decision, unfortunately, limited the period of time in which these two versions would be influential.  Even though both were quite popular prior to the Second World War, neither is widely read any more.  There style is too antiquated for most modern readers, and those who like the Elizabethan style have shown a preference to continue using the King James Version. (240)
