Otto Penzler's Sherlock Holmes Library

Anyone know anything about this? Bought one of the books from my favorite local used shop today and interested in any info I can find on it.

9 books (unless if I had missed the announcement for another one - and I doubt it) published in the 90s ('93, '94):

221B: Studies in Sherlock Holmes - orig. published 1940
Baker Street By-Ways- 1959?
Baker Street Studies - 1934
Holmes & Watson: A Miscellany - 1953?
My Dear Holmes: A study in Sherlock Holmes - 1951
The Private Life of Sherlock Holmes - orig. published 1933
R. Holmes & Co. -?
Seventeen Steps to 221B ?
Sherlock Holmes: Fact or Fiction? - 1932

The order is alphabetical -- don't have the publishing one here - just remembered that I have a list when I saw the question and decided to post it.

I believe that all of them were reissues of older books that are not exactly easy to be found - but I am not sure how accurate the dates I found back then were...

PS: And I believe all of them were fictional non-fiction (now that's a term I do not get to use every day) -- they would have been non-fiction IF Sherlock had been a real historical figure but they are technically written as non-fiction...
