Q: I have enclosed 2 pictures of the book in question (Julius Caesar). There is no ISBN or publishing date. I found you by looking up the publishing company. Any information you can give me about this book would be GREATLY appreciated.
A: Your book is part of the 39 volume Shakespeare’s Plays Series.
See http://henryaltemus.com/series/series164.htm
This particular volume was published sometime after 1900. There is nothing that distinguishes a 1900 book from a later book.
The books of this series are very common. Frequently in lots of 10-30 they sell for less than a dollar a copy if they sell at all.
