Tales of Blackwood

I have a four volume set of "Tales of Blackwood" no author listed. From what I can tell, this was published in 1905, but don't know for sure. On the last page of each volume is "printed by William Blackwood and Sons, Edinburg" I don't know the value of these, but would like to sell them. Is anyone interested? Respond to stgardn1@msn.com
