I am new to leather working and joined this group find out how it is  
done. Thanks to everyone who has contributed to this site. It has only  
been two days since I have signed up but I have learned a ton. I can't  
wait to get started. I thought I would share some online books that I  
found on Google Books. These are free to download since their copyrights  
have expired. If you want to do you own research on older books, use the  
advanced search feature on Google Books. Specify a date range where the  
ending date is Jan, 1923. Books published before that date are generally  
not subject to copyright protection in the US. Here are some of the  
books and journals I found.
